PHP - Query And Alter Data In An Associative Array
Hi and thanks for taking the time to read this and to help if you can
I have a flex app that is sending data to a php script that will then perform tasks based on the data found inthe array, my problem is that there are over 270 items in the array and I need to alter many of them BEFORE the script performs its task, what I need is a way to alter the data in the array without having to do it one at a time which I will have to do, below is some exxamples of what I am looking to do for example the array will have data on aprox 35 colors and I need to check and these values and change them if needed, my current system is as follows $color1 = $skin['color1']; if (preg_match("/0x/i", $color1)) { $color1 = str_replace("0x", "", $color1); } else { $color1 = str_pad(dechex($color1), 6, '0', STR_PAD_LEFT); } if($color1=="" || $color1=="000000"){$color1="100000";} now currently I would have to do this individualy for $skin['color1'], $skin['color2'], $skin['color3'] etc etc so is there a way I can do it without such bloated code, for example a while or a foreach statement etc? im not great at php so I am not sure how I would go about this if its possible another thing is that the rest of the values in the array are for image values and I need to fillter through them to find out which are the default images and which are not (no tasks are performed on default images) the following are example values from the array for the arrar item $clockface = $skin['clockface'] /home/thesite/public_html/flex_app/assets/default/clockface.png /home/thesite/public_html/flex_app/gallery/clock/clockface_3.png /home/thesite/public_html/flex_app/uploads/uploaded_file.jpg now depending on the value of the array I would wat the following for the 3 values above $clockface = ""; // if its the first value $clockface = "/home/thesite/public_html/flex_app/gallery/clock/pack3/clockface.svg" // if its the second value $clockface = "/home/thesite/public_html/flex_app/uploads/uploaded_file.jpg" // if its the third value now the above is easy to do on an individual basis but I want to streamline my code and not have an if statement with str_replace etc for each and every value which means I would have to do the code over 200 times for the images now as you can see from the first set of values there are certain things that give clues as to what and where the image is ("assests/default", "gallery/clock/clockface_3.png" and "uploads/uploaded_file.jpg") and I would use these to produce the final values above but again I would have to do it on an individual basis for each array value so is there any way I can streamline the process with again a while or a foreach statement or another way of doing this? your help is very much appriciated regards wayne Similar TutorialsHi, I'm trying to query my database using codeigniter's active record class. I have a number of blog posts stored in a table. The query is for a search function, which will pull out all the posts that have certain categories assigned to them. So the 'category' column of the table will have a list of all the categories for that post in no particular order, separated by commas, like so: Politics,History,Sociology.. etc. If a user selects, say, Politics and History, The titles of all the posts that have BOTH these categories should be returned. Right? So, the list of categories queried will be the array $cats. I thought this would work- foreach ($cats as $cat){ $this->db->like('categories',$cat); } By Producing this- $this->db->like('categories','Politics'); $this->db->like('categories','History'); (Which would produce- 'WHERE categories LIKE '%Politics%' AND categories LIKE '%History%') But it doesn't work, it seems to only produce the first statement. The problem I guess is that the column name is the same for each of the chained queries. There doesn't seem to be anything in the CI user guide about this (http://codeigniter.com/user_guide/database/active_record.html) as they seem to assume that each chained statement is going to be for a different column name. Of course it is not possible to use an associative array in one statement as it would have to contain duplicate keys- in this case every key would have to be 'categories'... Does anyone know how I could do this? Thanks! Hi there, Basic question, but I can't seem to find a page in the PHP docs that answers (though I'm sure such a one exists, I just can't seem to think up the right search terms - anyway) My question is: is there a short-hand way to use a value from an associative array as the key in another associative array? So for example, given this array: $the_array = array(0 => array('name': 'the_name', 'value' : 'the_value'), 1 => etc....); then this kind of foreach loop doesn't work Code: [Select] $new_data = array(); foreach($the_array as $element){ $new_data[$element['name']] = $element['value']; } Obviously I can just save out the values, like $name = $element['name'] --- but I was just wondering if there was a more efficient way to do it? Cheers, PS. I tried encapsulating with {} - i.e. $new_data[{$element['name']}] --- but that also fails. Hi, I want to develop array like following Code: [Select] $BCD=array('type' =>'TYPE1', array( 0=>array('column1'=>'value1','column2'=>'value1','column3'=>'value1','column4'=>'value1','column5'=>'value1','column6'=>'value1','column7'=>0), 1=>array('column1'=>'value1','column2'=>'value1','column3'=>'value1','column4'=>'value1','column5'=>'value1','column6'=>'value1','column7'=>0), 2=>array('column1'=>'value1','column2'=>'value1','column3'=>'value1','column4'=>'value1','column5'=>'value1','column6'=>'value1','column7'=>0), 3=>array('column1'=>'value1','column2'=>'value1','column3'=>'value1','column4'=>'value1','column5'=>'value1','column6'=>'value1','column7'=>0), ) )); I have written following code to achieve the same but not getting result. Code: [Select] $sql = "select * from tablename "; $result = mysql_query($sql); $k=0; while ($row = $db->mysql_fetch_array($result)) { // array_push($BCD['type'],$row['type']); $BCD1=array('type' =>$row['type'], array( $k=>array('column1'=>$row['column1'],'column2'=>$row['column2'],'column3'=>$row['column3'],'column4'=>$row['column4'], 'column5'=>$row['column5'],'column6'=>$row['column6'],'column7'=>$row['column7']) )); $k++; } I have a associative array and I need to compare it to a normal array. Code: [Select] associative will have anywhere from 2-8 of these ['name'] ['color'] ['uid'] Code: [Select] normal array will have anywhere from 1-8 names ['name'] What I need to do is get the name of the people that are in the associative array that are not in the normal array. I've tried all sorts of different loops and what not and I cant seam to get anything to work in every case. I have these two tables...
schedule (gameid, homeid, awayid, weekno, seasonno)
teams (teamid, location, nickname)
This mysql query below gets me schedule info for ALL 32 teams in an array...
$sql = "SELECT
h.nickname AS home,
a.nickname AS away,
h.teamid AS homeid,
a.teamid AS awayid,
s.weekno
FROM schedule s
INNER JOIN teams h ON s.homeid = h.teamid
LEFT JOIN teams a ON s.awayid = a.teamid
WHERE s.seasonno =2014";
$schedule= mysqli_query($connection, $sql);
if (!$schedule) {
die("Database query failed: " . mysqli_error($connection));
} else {
// Placeholder for data
$data = array();
while($row = mysqli_fetch_assoc($schedule)) {
if ($row['away'] == "") {$row['away']="BYE";}
$data[$row['homeid']][$row['weekno']] = $row['away'];
$data[$row['awayid']][$row['weekno']] = '@ '.$row['home'];
}
}
However, I only want to get info for one specific team, which is stored in the $teamid variable. This should be very easy, right? I have tried multiple things, including this one below (where I added an AND statement of "AND (h.teamid=$teamid OR a.teamid=$teamid)"), but this one still outputs too much...
$sql = "SELECT
h.nickname AS home,
a.nickname AS away,
h.teamid AS homeid,
a.teamid AS awayid,
s.weekno
FROM schedule s
INNER JOIN teams h ON s.homeid = h.teamid
LEFT JOIN teams a ON s.awayid = a.teamid
WHERE s.seasonno =2014
AND (h.teamid=$teamid OR a.teamid=$teamid)";
$schedule= mysqli_query($connection, $sql);
if (!$schedule) {
die("Database query failed: " . mysqli_error($connection));
} else {
// Placeholder for data
$data = array();
while($row = mysqli_fetch_assoc($schedule)) {
if ($row['away'] == "") {$row['away']="BYE";}
$data[$row['homeid']][$row['weekno']] = $row['away'];
$data[$row['awayid']][$row['weekno']] = '@ '.$row['home'];
}
}
Below is the array that the above outputs. In a nutshell, all I want is that 1st array ([1]) which has, in this example, the Eagles full schedule. It's not giving me too much else and I guess I could live with it and just ignore the other stuff, but I'd rather be as efficient as possible and only get what I need...
Array ( [1] => Array ( [1] => Jaguars [2] => @ Colts [3] => Redskins [4] => @ 49ers [5] => Rams [6] => Giants [7] => BYE [8] => @ Cardinals [9] => @ Texans [10] => Panthers [11] => @ Packers [12] => Titans [13] => @ Cowboys [14] => Seahawks [15] => Cowboys [16] => @ Redskins [17] => @ Giants ) [27] => Array ( [1] => @ Eagles ) [28] => Array ( [2] => Eagles ) [4] => Array ( [3] => @ Eagles [16] => Eagles ) [14] => Array ( [4] => Eagles ) [15] => Array ( [5] => @ Eagles ) [3] => Array ( [6] => @ Eagles [17] => Eagles ) [] => Array ( [7] => @ Eagles ) [16] => Array ( [8] => Eagles ) [25] => Array ( [9] => Eagles ) [11] => Array ( [10] => @ Eagles ) [7] => Array ( [11] => Eagles ) [26] => Array ( [12] => @ Eagles ) [2] => Array ( [13] => Eagles [15] => @ Eagles ) [13] => Array ( [14] => @ Eagles ) ) Hi guys. I have an associative array called $VisitorCountryID $VisitorCountryID = filter_countries(array('Country' => $_SESSION['UserCountryName'])); and the function filter_countries() returns all the information relating to the visitors country from the database. To find out what we have in the array, we do: print_r($VisitorCountryID); and it gives us: Array ( [14] => Array ( [CountryId] => 14 [Country] => Australia [FIPS104] => AS [ISO2] => AU [ISO3] => AUS [ISON] => 36 [Internet] => AU [Capital] => Canberra [Comment] => ISO includes Ashmore and Cartier Islands,Coral Sea Islands [sortOrder] => 1 ) ) Which is OK. Now i just want the CountryId which you can see in the array is 14 therefore I write: print_r($VisitorCountryID['CountryId']); Which should give me 14 but it return blank no output. I am surprised. What do you think is missing here. Any response / feedback always welcomed! Cheers! I WANT HELP WITH ASSOCIATIVE ARRAY THERE IS ARRAY LIKE THIS $ARRAY= array( 'dd'=>1, 'dde'=>233, 'qww'=2231 ) i want to store this array in database which data type i should i use want to use mixed data mixed string-numeric type which data type is suitable and i want to print indexes only but values only what should i do Hello all!! I need help with an associative array I've been working on. I'm not sure if I should have typed the weekday in the index because I'm supposed to use the getdate() function to pull the day of the week into the array. I'm also supposed to use string functions to pull apart the value where it's connected with the colon ":". I've tried using explode() and strtok but I don't quite understand how they work...just like the getdate()..I don't understand. Thanks for any 'nudge' in the right direction you can offer.

I am running linux and php5.3.6 I am having problems that I did not experience on my Windows box and it has to do with arrays if ($answer['correct']) { (which contains 1 or 0) is throwing Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING removing the quotes works but just curious why it is not working and if there is a setting i can change Also $answers[] = $answer[id]; is throwing Parse error: syntax error, unexpected ']', expecting T_STRING or T_VARIABLE or T_NUM_STRING Thank you to anyone who might be able to help. I'm scraping a housing website with html source: Code: [Select] <tr><td> </td><td> Bedrooms </td><td> </td><td >3</td><td> </td></tr> <tr><td> </td><td> Full Baths </td><td> </td><td >1</td><td> </td></tr> <tr><td> </td><td> Partial Baths </td><td> </td><td >1</td><td> </td></tr> <tr><td> </td><td> Interior Sq Ft </td><td> </td><td >1,356</td><td> </td></tr> <tr><td> </td><td> Acres </td><td> </td><td >0.16</td><td> </td></tr> What i'm trying to do is create an associative array with only the details I want from the above. I've already got a function that steps through the HTML and creates an array element for each row with the contents of each <td> statement as follows: Code: [Select] $repl = array(" ", "(", ")"); $repl_with = array("", "", ""); foreach ($rows_feat as $id2 => $row2){ $features_raw = $scrape->fetchAllBetween('<td','</td>',$row2,true); //$features_data[str_replace($repl,$repl_with,strtolower(trim($features_raw[1])))] = trim($features_raw[3]); $countid=$countid+1; } The array produced by this would look like: features_raw[1] = Bedrooms features_raw[3] = 1 Basically, I want to take data like this: Beds 1 Baths 1 Garage Yes and create an array on the fly: House[beds]=1 House[baths]=1 House[garage]="yes" The problem is that the order of Beds, Baths and Garage changes. So on some house pages the order would be Baths, Garage, Beds.. etc. Any pointers out there? Thanks, Brett Hello I have been taking a look at associative arrays. I 'sort' of get the key/value idea, but I'm not quite sure if they appropriate for use with 3 items (as opposed to the 2 key/value items.) In the code below, I can incorporate the 'company' and 'table' values - but I'm not sure how to add the 'id' value (from the query). I would very much appreciate some guidance here. Thank you. Code: [Select] $a = array(); // 'A' table array $b = array(); // 'B' table array $c = array(); // 'C' table array $query = "SELECT id, company, `table` FROM EXHIBITORS WHERE year = $year ORDER BY company ASC"; $result = mysql_query($query) or die("There was a problem with the SQL query: " . mysql_error()); if (mysql_num_rows($result) > 0) { while($row = mysql_fetch_array($result)) { $testCol = substr($row['table'], 0, 1); if ($testCol == 'A') { $a[$row['company']] = $row['table']; } else if ($testCol == 'B') { $b[$row['company']] = $row['table']; } else if ($testCol == 'C') { $c[$row['company']] = $row['table']; } } echo "<table>"; foreach($a as $key => $value){ echo "<tr><td>company: $key</td><td>Table: $value </td></tr>"; } echo "</table>"; echo "<table>"; foreach($b as $key => $value){ echo "<tr><td>company: $key</td><td'>Table: $value </td></tr>"; } echo "</table>"; echo "<table>"; foreach($c as $key => $value){ echo "<tr>"<td>company: $key</td><td>Table: $value </td></tr>"; } echo "</table>"; } else { echo "No Exhibitor data for the year $_POST[selectByYear]"; } <HTML> <?php $arr = array("sue" => "betsy", "frank" => "marge"); ?> </HTML> This produces the following HTML page: "betsy", "frank" => "marge"); Its like when I use the => to make my associative array, the code thinks I'm closing the php codeblock and then just prints the rest of it to the screen... Hi there! Ok I've a very simple code he $character = array (name=>"Joe", occupation=>"Programmer", age=>30, "Learned language "=>"Java" ); print_r($character); echo "<br/>"; foreach ( $character as $key=>$val ){ print "$key = $val <br>"; } The output is: Code: [Select] Array ( [name] => Joe [occupation] => Programmer [age] => 30 [Learned language ] => Java ) name = Joe occupation = Programmer age = 30 Learned language = Java Now instead of returning all the other elements, I just need to display only the first element in the array that is the value 'Joe'. I tried $val[name]; Output I get is not what I want: Code: [Select] J P J All responses/feedbacks is always welcomed Thank you! i have problem to get the sum from the associative array. i have to get sum for the 3 result that being display from the array

Hi guys, I'm really struggling trying toremove duplicates from an associative array. I've tried array_unique but it doesn't work. Can you point me in the right direction please? I'm populating my array using the following code Code: [Select] foreach($category['manufacturers'] as $manufacturer) { list($name, $id) = explode("|", $manufacturer); $brands[] = array("id" => $id, "name" => $name); } If the array contains: id = 1, name = brandA id = 2, name = brandB id = 1, name = brandA I'd like to remove either the first or third entry. I always struggle with associative arrays i need some help sorting my arrays. i have a class that selects data from database, and holds it inside a class to be used multiple times. rather then executing multiple queries. i know how to sort an array. but i am sorting arrays inside an array $data = arrray( array( 'id'=>1, '_name'=>'Server A', '_date_added'=>1298207645.5424, ); array( 'id'=>2, '_name'=>'Server B', '_date_added'=>1298247384.4839, ); array( 'id'=>3, '_name'=>'Server C', '_date_added'=>1298218493.0493, ); ); i want to sort my array descending by key _date_added hope you understand... I am trying to write a shopping cart script, that once they have confirmed their order it will insert into the database their order information. Basically as a product can have a number of different quanitities that they wish to purchase, I want to create an associative array that has a product, linked to the quantity. I want to do this so that the order information stays in one row in the database, so in the 'product' row, it has values like (cow -> 2) cow being the product and 2 being the quantity. Here is the code I am developing, and I have commented in the array which I am trying to create just the show my idea of thinking. any help, will be greatly appreciated! function updateCart($product_id,$id){ if($_SESSION['cart']) { foreach($_SESSION['cart'] as $product_id => $quantity) { $total = 0; $sql = sprintf("SELECT title, price, shipping FROM product WHERE pkID = %d;",$product_id); $result = query($sql); if(numRows($result) > 0 ){ $row = getResult($result); $price = $row['price']; $shipping = $row['ship']; $line_cost = ($price + $shipping) * $quantity; $total = $total + $line_cost; $product[] = $row['title'] -> $quantity; //unsure of how to code $sql2 = "INSERT INTO cart (userID, products, total, date) VALUES ('$id', '$product', '$total' '$date')"; $query = query($sql2); } } }else{ $alert = 'No items in shopping cart.'; } return $total; } I am an ASP.NET developer and I have to call a soap methed written in PBP that takes an argument required an associative array such as $prices = array( 'Tires'=>'test1', 'Spark Plugs'=>'test2' ); can yoiu tell me what the internal representation is of the above Hi guys
A mobile application send data in Json format, so I want to insert the data into Mysql table, when I try to insert I have gotten the error "PHP Warning: mysqli::prepare() expects exactly 1 parameter, 3 given", my table only has 2 columns, "id" and "name" column.
The array has this data
(
[0] => ('id', '2')
[1] => ('name', 'Jhon')
)
The function to parse and insert data ...
function redeem() {
// Check for required parameters
$json = file_get_contents('php://input');
$obj = json_decode($json,true);
// Assumes $obj == array(0 => $assocArray, 1 => $assocArray)
foreach($obj as $index => $assocArray) {
// Assumes $assocArray == array(0 => array('id' => '2'), 1 => array('name' => 'John'))
$stmt = $this->db->prepare('INSERT INTO prueba (id,nombre) VALUES (%d,%s)',$assocArray[0]['id'],$assocArray[1]['name']) or die(mysqli_error($this->db));
$stmt->execute();
}
}
Edited by Maq, 06 June 2014 - 03:54 PM. I came up with this but it outputs the value 3 times... (because there are 3 variables) ie mathsmathsmaths How do I fix this or do it the correct way? Thanks Code: [Select] $subject = "maths"; $phone = "1235"; $colour = "red"; $all_vars = compact("subject", "phone", "colour"); get_value($subject); function get_value($variable){ global $all_vars; foreach($all_vars as $key=>$value){ if ($key = $variable) { echo $key; } } } |
