PHP - Create An Array Based On Array Key
Hi,
I am working on a betting API, The data comes from an XML Feed. I am using a PHPPhar file to iterate the XML data, Seems to work really well. What I need to do now is iterate each "outcome" type and order it by the highest decimal to lowest decimal value (Best odds) My current array of data from the XML looks like this (See pastebin for full version) :
SimpleXMLElement Object

Is it possible build an array of outcomes, Then sort by the best decimal price. (I have a function built that can convert the "currentPrice" to decimal.
Thnak You!
Similar TutorialsLooking for tutorials, but maybe the forum's quicker. Can anybody give me a loose idea how to do this? I have a sequence of pages that the user goes through to enter information. I need to move a page up to pull data before inputting to the database - to prevent some dropped entries and errors. Before, it was using info in the database to loop through and generate data. I want to do it just based on the info in an array: I want array(217 => 1, 215 => 2); to loop generate a form that loops through to create something like: Code: [Select] <form> Student one, Class 217<br> First name: <input type="text" name="fname[]" id="fname" onfocus="this.className='reg_live';" onblur="this.className='reg_off';" /> Last name: <input type="text" name="fname[]" id="fname" onfocus="this.className='reg_live';" onblur="this.className='reg_off';" /> <br><hr><br> Student one, Class 215<br> First name: <input type="text" name="fname[]" id="fname" onfocus="this.className='reg_live';" onblur="this.className='reg_off';" /> Last name: <input type="text" name="fname[]" id="fname" onfocus="this.className='reg_live';" onblur="this.className='reg_off';" /> <br><br> Student one, Class 215<br> First name: <input type="text" name="fname[]" id="fname" onfocus="this.className='reg_live';" onblur="this.className='reg_off';" /> Last name: <input type="text" name="fname[]" id="fname" onfocus="this.className='reg_live';" onblur="this.className='reg_off';" /> <br><hr><br> and so on. <input type="submit" value="Register" /></form> NOTE - Please read the information first as it contains important information to understand the problem.

PROBLEM : I am unable to understand what should possibly be the logic & loop used here for creating a MATRIX ALLOCATION MAP as shown above I have tried while, foreach & for but unable determine the perfect combination which would meet the conditions. (Tried all of the above with Nested Loops also) Edited May 1, 2020 by AlphaMikeTags Hello can anyone help me out with code to create a 2 dimension array from 2 single dimension array. for example $path = array('base', 'category', 'subcategory', 'item'); $location=array('india','USA','UK','RUSSIA',); now i need to have a @D array which have the following structure $final[0]=array('base','india'); $final[1]=array('category','USA'); $final[2]=array('subcategory','UK'); $final[3]=array('item','RUSSIA'); I'm creating a tool for building project proposals for clients, with pricing. I have a database with two tables: services and clients. The services table looks like this: Code: [Select] | code | name | cost | +-------------+-------------+------+ | logo_design | Logo design | 10 | | web_design | Web design | 20 | The clients table looks like this: Code: [Select] | id | client | logo_design | web_design | +----+---------+-------------+------------+ | 1 | Walrus | yes | yes | | 2 | Narwhal | no | yes | How would I link the results from these two tables so that I only pull out the services each person wants from the database? Here is what I have so far: Code: [Select] <? $sql = "SELECT * FROM services"; $result = mysql_query($sql); while ($row = mysql_fetch_array($result,MYSQL_ASSOC)) { echo $row{'name'} . ': $' . $row{'cost'} . '<br />'; } ?> This, of course, displays all the services, with all the prices, like so: Logo design: $10 Web design: $20 I want to add something here so that based on the selected client, we see only the services/prices they selected (ol' Narwhal's page would not show the "Logo Design" line). I've got the data from "clients" pulled in to this page as well, but don't know how to relate it to "services." Thanks in advance! Let me know if I've left out any info that would help you to point me in the right direction. Hi, Here is simple question. I have this array: array([0]=>name [1]=>Tony); How can i change into array(name=>Tony); ? Thank you, ayok First off, what are the names for the types of arrays? What do you call an array that uses integers for the key? I think when the key is text it is called an associative array? Anyways...
Is there a way to create an array where they keys are integers, but you are defining the first entry? I would like my array to either start with a "1" or maybe "1001". How do I do that?

What i want to do is: make an array with two keys. 'id' and 'distance'. I want to sort the results by distance, displaying the id's... im looking at ksort() as the solution, however i don't think im implementing it properly as i dont think i have set the array up properly!! what i have is not good... Code: [Select] <?php while ($row = mysql_fetch_array($result)) { //get the photographers postcode and split it into 2 pieces $p_postcode = explode(' ',$row['address_post_code']); //get the photographers postcode and split it into 2 pieces $u_postcode_a = explode(' ',$u_postcode); //run the two postcodes throught the function to determin the deistance $final_distance = return_distance($u_postcode_a[0], $p_postcode[0]); //start the variable so we can add to it later on $photographers_inrange = ""; //declare this variable to help with the comma spacing too EDIT LOOK TO LINE 46 //$i2 = 1; $photographers_inrange = array(); //if the distance is smaller or equal to the distance the photographer covers if($final_distance <= $row['cover_distance']){ //get their id $photographers_inrange['id'] = $row['ID'].','; $photographers_inrange['distance'] = ''.$final_distance; //echo $photographers_inrange; //EDIT: this method does not work when just one result is returned. now i use substr -1. //if this isnt the last result //if($i++ <= $i2++){ //then add a comma for the sql statement //$photographers_inrange .= ','; //} } ksort($photographers_inrange); foreach ($photographers_inrange as $key => $val) { echo "togs[" . $key .

What I have, is this: <?php $data = array( 1 => array( "name" => "Jordan Smith", "age" => "16 Years 0 Months" ), 2 => array( "name" => "Olivia Smith", "age" => "13 Years 12 Months" ) ); Now, what I did, is I constructed this: while($result=$data[1]) { echo $result['name']; } But it echoed "Jordan Smith" for infinity down the page. If anyone can help be do this, it will be great. Thanks Hi I was just wondering would it be possible to create a database from a input statement and array, if so would it be also possible to create a table with fields the same way? Friends, I have a PHP script that populates a calendar based on an array as follows: $days = array(2=>array('javascript:showWhatsOnText(2);','linked-day'), 3=>array('javascript:showWhatsOnText(3);','linked-day'), 4=>array('javascript:showWhatsOnText(4);','linked-day')); echo generate_calendar(2011, 4, $days, 1, '#'); where, for instance, the 2, 3 4 are the days of the month, By extracting a series values from a MySQL database how would I generate this array dynamically. E.g I have startday, startmonth, name and text fields in the database and would need to loop through them all to create the array. I tried playing around with something like this without any luck: $queryCat1 = "SELECT * FROM $dbCalendarEvents ORDER BY id ASC"; // WHERE visible = '1' $result1 = mysql_query($queryCat1) or die (mysql_error()); $num1 = mysql_num_rows($result1); $i=0; $daysArray = array(); while ($i < $num1) { $startday=mysql_result($result1,$i,"startday"); $startmonth=mysql_result($result1,$i,"startmonth"); $name=mysql_result($result1,$i,"name"); $name=mysql_result($result1,$i,"name"); $copy=mysql_result($result1,$i,"copy"); $daysArray[$i] = $startday=>array('/weblog/archive/2004/Jan/02','linked-day'); $i++; } Your help is appreciated. Here is my code:
//Grab all the monster in Monster zone 1
$q = $db->query('SELECT * from rpg_monsters where monster_zone = 1');
while ($monsterdata = $db->fetch_assoc($q))
{
$monster_chance[] = $monsterdata;
}

$max = 1 / $rate; // 100
if (mt_rand(0, $max) === 0) {
// chance < $rate
echo "Only 3% probability, holy cow!";
}
My problem is, I'm a bit lost as how to get my probability code inside a loop and having the dynamic $rate correspond to my "chance" row.
Although, I could just use ORDER BY rand() in mysql, it wouldn't let me use any probability and chances... hmmm
Edited by Monkuar, 12 October 2014 - 11:12 AM. Hi, I have an array filled with values like this: Code: [Select] string(1) "Acer 1" string(2) "Acer 2" string(3) "Dell 1" string(4) "Dell 2" string(5) "Dell 3" string(6) "Dell 4" string(7) "Acer 3" string(8) "Acer 4" Is there a way to successfully remove all array strings that starts with a given value like "Acer"? I tried with this snippet, does not work: Code: [Select] foreach($array as &$value) { if(preg_match("/^Acer/", $value)) { unset($value); } } Any ideas will be appreciated! Hello Guys This is the first time i ask a question at php freaks. Hope i could find the answer. I want to create something similar to the image now the problem is that i want to get groups and their users in the same array. Notice something like Array => Group1 [1] => user1 [2] => user2 [3] => Group2 and so on. How could i do that. Thanks in advance. Hello to everyone,
I have a strange problem and I'm not able to solve it by myself and I need your help!
I have three simple checkboxes that process via POST their value. But with PHP I cannot have an array with the three indexes (if everyone checked) but only an array with the first checkbox checked. The code is very simple:
<?php
$scelta = isset($_POST['user_rights']) ? $_POST['user_rights'] : array();
if
(isset($_POST["user_rights"])){ print_r($scelta);}else{
?>
<form method="post"><input type="checkbox" name="user_rights[]"
value="0"> 0<br><input type="checkbox" name="user_rights[]"
value="1"> 1<br><input type="checkbox" name="user_rights[]"
value="2"> 2
<input type="submit"></form>
<?php}
?>
The output if I check all the checkboxes is:
Array ( [0] => 0 )
If I try this code on another server it works (it returns the complete array), but if i run it on my web server, it doesn't (it returns only the first item). Do you have any experience with this error? Do you know if there is some configuration to change?
Thanks in advance.

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; } Hi, I have attached sql script for table structure and sample data. When I run following sql query ,I get result set. Code: [Select] select * from tablename order by col10 desc I want to create array using result set. Following is the require structure of array. Code: [Select] <?php $resultSet[]=array ( ('0') =>array ( ('col10value1') => array ( ('0') => array ( ('col1') => 'col1', ('col2') => 'col2', ('col3') => 'col3', ('col4') => 'col4', ('col5') => 'col5', ('col6') => 'col6', ('col7') => 'col7', ('col8') => 'col8', ), ('1') => array ( ('col1') => 'col1', ('col2') => 'col2', ('col3') => 'col3', ('col4') => 'col4', ('col5') => 'col5', ('col6') => 'col6', ('col7') => 'col7', ('col8') => 'col8', ), ), ), ('1') => array ( ('col10value2') => array ( ('0') => array ( ('col1') => 'col1', ('col2') => 'col2', ('col3') => 'col3', ('col4') => 'col4', ('col5') => 'col5', ('col6') => 'col6', ('col7') => 'col7', ('col8') => 'col8', ), ), ), ); ?> Hi there, I'd be ever so greatful if someone could help me please. I'm really trying to get my head around working with arrays and could really do with an example in a context i fully understand. I have made a test page for this and made a query that will search for appropriate records in my database: Code: [Select] <?php $colname_Class = "3"; $colname_Ships = "-1"; if (isset($_SESSION['MM_Username'])) { $colname_Ships = (get_magic_quotes_gpc()) ? $_SESSION['MM_Username'] : addslashes($_SESSION['MM_Username']); } mysql_select_db($database_swb, $swb); $query_Ships = sprintf("SELECT * FROM ships WHERE PlayerName = %s AND Class=%s AND Template='1'", GetSQLValueString($colname_Ships, "text"), GetSQLValueString($colname_Class, "int")); $Ships = mysql_query($query_Ships, $swb) or die(mysql_error()); $row_Ships = mysql_fetch_assoc($Ships); $totalRows_Ships = mysql_num_rows($Ships); echo $row_Ships['ShipID']; echo ' '; echo $row_Ships['ShipName']; echo ' '; echo $row_Ships['Class']; echo ' '; echo ' '; echo $totalRows_Ships = mysql_num_rows($Ships); ?> After i made the query i echo out the ShipID, ShipName and Class from the queey which displays: 5 New Ship 3 1 So you can see the ShipID = 5, the name of the Ship is New Ship, its Class is 3 and there is only 1 record found in the database that matches the search criteria. Lets say there are 10 records in my database... What i really need to do is make an array of the outputted results, determine the number of records and then to randomly choose 1 of the results from the array. Can you help me please?? If i can see an example in this context i feel i'd really learn something here. If you can help, please do because im well stuck. Thank you Tom |
