PHP - Auto Replace Array Values ?
Hello, I am a newbie PHP hobbyist. I mess with php strictly for my own amusement. Up until now I have been able to Google my way to a answer to my questions but I'm lost on this one. I'm not really sure what to even search for.
I have a few different mysql queries that returns the following arrays. qid15=37,37,37,37,37,37,37,37,37,37,37,38,38,39,39,41 qid17=47,47,47,47,47,48,49,49,49,50,50,50,51,51 qid18=52,52,52,52,52,52,52,52,54,54,55,55,55,56,56,56 qid19=57,57,57,57,58,59,59,61,61 What I would like to do is replace or create a new array for each result with the lowest value as 1 the next lowest as 2 then 3 and 4. My new array would look something like this oldqid15=37,37,37,37,37,37,38,38,39,39,41 newqid15=1,1,1,1,1,1,2,2,3,3,4 I sure would appreciate any ideas on this. I'm thinking there is probably a simple solution and before I waste anymore time I'll stop and ask for directions(as my wife would suggest). Similar TutorialsHi, If i had the following array: $test = array('key1'=>'test1', 'key2'=>'value2', 'key3'=>array('test','test1','test2')); Is there a way i could change all the values that have the word "test" to "hello"? So basically end up with the following array: $test = array('key1'=>'hello1', 'key2'=>'value2', 'key3'=>array('hello','hello1','hello2')); Is this possible? Thanks I know you can use str_replace to replace a value with another value, or an array of values with an array of other values. What I'd like to do is replace each instance of a single value with an array of values which get iterated through for each instance found. Think prepared statements that you don't have to call setString or setInt on. Here's a made up example. Code: [Select] $db->query = 'SELECT * FROM users WHERE user_name = ? AND user_role = ?; $db->params = array('hopelessX','admin'); $db->executeQuery(); //this contains a call to a private function that does the replace I have everything else working except this. It works if I specify an array of values to replace and do something like below, but I was hoping to not have to support that method of replace if I didn't need to. Code: [Select] $db->query = 'SELECT * FROM users WHERE user_name = :name AND user_role = :role; $db->replace = array(':name',':role'); $db->params = array('hopelessX','admin'); $db->executeQuery(); //this contains a call to a private function that does the replace I can do it that way if I need to or I could make some overly complicated thing that finds each instance of the question mark, replaces it with a unique value and then adds that unique value to a replace array similarly to the method in code block two but that defeats to the purpose of making this simple database adapter in the first place (although it was mostly just for fun anyway). Anyway, if anyone has any advice and knows of a simple means to achieve this goal that would be much appreciated. Thanks in advance hi is there a way of doing a str replace to look twice like at moment i have if find space replace with "-" PHP Code: Code: [Select] .str_replace(' ','-',($row['model'])) is there a way i can do if find twice $row['model if find space " " replace with "-" also if find "i30" replace with "10" is there a way i can try find another like if find " " replace with "-" also if find "130" replace with hello world?? thanks in advance Short question: How can I get a string of HTML code and replace all the <input> tags with their values? Long question: I have a web page with a purchase order on it in HTML format and one or more of the columns is editable via input boxes. So the user can change the quantity/length of the material before submitting it. Once they choose to save it, it sends the string of HTML to a PDF generator (DOMPDF) which converts the HTML to a PDF file and saves it to the server. The user then has a hard copy of the purchase order PDF saved for each job. The problem is DOMPDF doesn't do well with <input> tags, it just leaves them as a blank space. So I want to take that string of HTML and replace all input boxes with their values before sending it to DOMPDF. Currently I'm using Javascript to do just that when the user clicks to save the modified purchase order. The problem with this is it only works for when the user modifies the purchase order and saves a new modified copy. I need to save a base unmodified copy of it when the page loads so this would strip all the input boxes from the page as soon as it loads and the user would no longer be able to edit anything. So I need something to send the string to DOMPDF when the page loads but not modify what's on the page. Any ideas? Thanks. ok, how do I add an auto incremented value to another table at the same time the value is created. so I will do a query to insert into db, and it creates auto incremented value of 1, then I need this value to also be put into another table just as text. how do I go about doing this? I need this all in one query. Hi all, I'm a first time poster here and I would really appreciate some guidance with my latest php challenge! I've spent the entire day googling and reading and to be honest I think I'm really over my head and need the assistance of someone experienced to advise the best way to go! I have a multi dimensional array that looks like (see below); the array is created by CodeIgniter's database library (the rows returned from a select query) but I think this is a generic PHP question as opposed to having anything to do with CI because it related to working with arrays. I'm wondering how I might go about searching the array below for the key problem_id and a value equal to a variable which I would provide. Then, when it finds an array with a the matching key and variable, it outputs the other values in that part of the array too. For example, using the sample data below. How would you recommend that I search the array for all the arrays that have the key problem_id and the value 3 and then have it output the value of the key problem_update_date and the value of the key problem_update_text. Then keep searching to find the next occurrence? Thanks in advance, as above, I've been searching really hard for the answer and believe i'm over my head! Output of print_r($updates); CI_DB_mysql_result Object ( [conn_id] => Resource id #30 [result_id] => Resource id #35 [result_array] => Array ( ) [result_object] => Array ( ) [current_row] => 0 [num_rows] => 5 [row_data] => ) Output of print_r($updates->result_array()); Array ( [0] => Array ( [problem_update_id] => 1 [problem_id] => 3 [problem_update_date] => 2010-10-01 [problem_update_text] => Some details about a paricular issue [problem_update_active] => 1 ) [1] => Array ( [problem_update_id] => 4 [problem_id] => 3 [problem_update_date] => 2010-10-01 [problem_update_text] => Another update about the problem with an ID of 3 [problem_update_active] => 1 ) [2] => Array ( [problem_update_id] => 5 [problem_id] => 4 [problem_update_date] => 2010-10-12 [problem_update_text] => An update about the problem with an ID of four [problem_update_active] => 1 ) [3] => Array ( [problem_update_id] => 6 [problem_id] => 4 [problem_update_date] => 2010-10-12 [problem_update_text] => An update about the problem with an ID of 6 [problem_update_active] => 1 ) [4] => Array ( [problem_update_id] => 7 [problem_id] => 3 [problem_update_date] => 2010-10-12 [problem_update_text] => Some new update about the problem with the ID of 3 [problem_update_active] => 1 ) ) Here is my code Code: [Select] if (isset($_GET['hide'])){ $id = intval($_GET['hide']); $explode = explode(",", $_COOKIE['hide']); if (in_array($id, $explode)) { } setcookie('hide', ''.$id.'',time()+32000000); header('Location: index.php'); exit; } My Explanation: If somone clicks ?hide=2 It will add the cookie hide, and the value to 2. Now, if somone clicks ?hide=1, I need it to add 2,1 how is that possible? Then if the in_array is correct, (Means if the value of the cookie is 2 and they clicked ?hide=2) how do I take that number "2" out of the it (Remove it) and make a new array that will be inserted to my $id variable?

Thanks Hello, how could I do a replace using one array? Example: Code: [Select] $changes = array( "{NAME}" => $name, "{CHANGED_PART}" => $desc, "{CHANGE_D}" => date("j"), "{CHANGE_M}" => date("n") ); And then I would want to replace all parts in the left with parts in the right inside a string.Is that possible ? thank you.. Hi everyone,
I have an application that makes use of a transaction, inserting and updating values in different tables. One of the first tables it inserts into has an auto increment ID field. This ID values is used / updated in some other tables. Everything works fine. If however the transaction fails then the auto_increment values are upset - meaning that the sequence is jumped.
For ex. if I had auto_increment values from 1 to 6 in this table and then the insert query fails for an auto_increment value of ID=7, then this value of ID = 7 is lost because the next time the query is run the auto_increment ID value will be equal to 8 and accordingly updated in the tables. ID value = 7 is lost. Is there any way to prevent this ? Please know that this is a multi - user application.
Thanks.
Hey i hope the title explains it enough. I'm just trying to get into classes. I am making a function to make making mysql querys easier. I pass the class the first string $db->inputstring("INSERT INTO ? (?,?) VALUES ('?','?')"); $db->format('mytable','id','name','1','ben'); Can someone tell me how the format fuction would look? Im not sure how to swap arrays. hi, i am trying to visualize a table by replacing the fixed values with images. For example, i have a visitor statistics table on mysql. Values on the config_os table are always in three letters. WI7 for Windows7, MAC for Macintosh. I hope I can tell this correctly. I have a display page which retrieves the values from database and displays them website statistics. But in order to make it more cool, i am telling to PHP that When you echo to divtable WI7, replace them with specified Windows7 icon image which has identical name as WI7.gif. Here is the code: Code: [Select] include("conn.php"); $sql="SELECT *, INET_NTOA(location_ip) AS location_ip FROM xx_log_visit AS location_ip ORDER BY idvisit DESC LIMIT 10"; // I am selecting all so you can't see config_os but it is there . I cropped unnecessary code for keeping it easy to read. $result=mysql_query($sql); $numofrows = @mysql_num_rows($result); while($row = mysql_fetch_array($result)) { $system = $row['config_os']; $SysName = array ("AND", "IPH", "LIN", "MAC", "UNK", "W2K", "W95", "W98", "WI7", "WME", "WNT", "WOS", "WS3", "WVI", "WXP"); $SysRename = array ("<img src='images/os/AND.gif'>","<img src='images/os/IPH.gif'>","<img src='images/os/LIN.gif'>","<img src='images/os/MAC.gif'>","<img src='images/os/UNK.gif'>","<img src='images/os/W2K.gif'>","<img src='images/os/W95.gif'>","<img src='images/os/W98.gif'>","<img src='images/os/wi7.gif'>","<img src='images/os/WME.gif'>","<img src='images/os/WNT.gif'>","<img src='images/os/WOS.gif'>","<img src='images/os/WS3.gif'>","<img src='images/os/WVI.gif'>","<img src='images/os/WXP.gif'>"); $showsystem= str_replace($SysName, $SysRename, $system); What I do here is simply use strreplace function. $showsystem = str_replace($SysName, $SysRename, $system); and in the display table, continue from code: Code: [Select] echo (" <div class='sub15'>$showsystem</div> " ); } So for example instead of writing WI7 as visitors os, it shows WI7.gif, cool hmm How can i automate this instead of writing each of them separately? Thanks for any help.. I have mysql select query shown below retrieving data from a database:
$sql = "
SELECT
student, sum( test_score ) as score
FROM
test
INNER JOIN
level
ON
test.level_id = level.level_id
GROUP BY
student"
$result = $mysqli->query($sql, MYSQLI_STORE_RESULT);
if($result)
{
while ($row = $result->fetch_array(MYSQLI_ASSOC))
{
var_dump($row);
}
}
On inspection of the retrieved array with var_dump(), i have these result below:
array (size=2) 'John' => string 'English' (length=2) 'Score' => string '20' (length=3) array (size=2) 'Mary' => string 'Math' (length=3) 'Score' => string '35' (length=3) array (size=2) 'Samuel' => string 'Physics' (length=3) 'Score' => string '5' (length=3)How do I get at and print out the highest score from this set of array values within this context. I tried this echo max($row['count']) but i understandably got this feedback: Warning: max(): When only one parameter is given, it must be an array Thanks. Hello all, I have yet again trouble finding a logical solution to my problem. I'm fetching an array which can hold 1 or more values. The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values. I can't explain it further, so here's the code so far: Code: (php) [Select] $files = mysql_fetch_array($get_files); $a = count($files); $i = 1; while ($files) { $variablename = 'fileName' . $i; $$variablename = $files['fileName']; $i++; } $output = array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are? This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works? Thank you. 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. I need to some how pull comma separated images $data[23] from this $data array and then put them into there own array so I can insert them into separate rows in a database. This is the provided array: $data[0] => VIN $data[1] => StockNumber ...(all the other number here) $data[23] => Image_URLs (comma seperated) $data[24] => Equipment // I need something like this (obviously doesn't work?!@#) $delimiter = ","; $img = explode($delimiter, $data[23]); foreach($img as $pic){ $sqlPic = "insert into class_prodimages (pid image rank) values('".$LastId['id']."', '$pic', '".rand(1,20)."')"; } Any help here? I have an array created to control the down states of the my buttons in my navigation. Which is working well. This array will have quite a few strings in it before I'm done. I then want to conditionally load a CSS file for all the files in that array with the exception of two, is this possible? In plain in english I want to say If in array apart from these values then load my css file. My array (will have more values when complete) Code: [Select] $otherTitles = array('Product Selector', 'Avon Range', 'Knightsbridge Range', 'Kingston Range' ); My code to load a css file Code: [Select] <?php if (in_array($title, $otherTitles)) { ?> <link rel="stylesheet" type="text/css" href="homepage.css"/> <?php } ?> I want all titles in the otherTitles array to get this CSS file apart from two Product Selector and Avon Range. Thanks Richard I have the following array structu Code: [Select] [0] => Array ( [id] => Array ( [$t] => http://www.google.com/mate/ ) [updated] => Array ( [$t] => 2011-08-31T11:43:05.942Z ) [category] => Array ( [0] => Array ( [scheme] => http://schemas.google.com/g/ [term] => http://schemas.google.com/contact/ ) ) [title] => Array ( [type] => text [$t] => Name ) [link] => Array ( [0] => Array ( [rel] => http://schemas.google.com/contacts/2008/rel#edit-photo [type] => image/* [href] => https://www.google.com/mate/feeds/photos/media/ ) [1] => Array ( [rel] => self [type] => application/atom+xml [href] => https://www.google.com/mate/feeds/contacts ) [2] => Array ( [rel] => edit [type] => application/atom+xml [href] => https://www.google.com/mate/feeds/ ) ) [gd$email] => Array ( [0] => Array ( [rel] => http://schemas.google.com/g/2005#other [address] => email_address@gmail.com [primary] => true ) ) ) I am tried to display name and email address.
