PHP Functions

Function: array2vars
By dave

Note! This function is not a built-in PHP function. To use it, you will need to copy the source code (located at the bottom of this page) into your script.

array2vars -- Converts an array into a set of variables, where the keys become the variables' names.

Description

void array2vars ( array KeysWithValues )

This function can be useful in converting your $_POST values into distinct variables. This way, you can just type $keyName instead of $_POST['keyName']. Other similar arrays include $_GET, $_REQUEST, $_SESSION, $_COOKIE; and an array (or row) fetched from your mySQL database, as exemplified in example 2.

Note! It was pointed out by a visitor that the function extract (see related functions) does the exact same thing.

Example 1. array2vars() example

<?php
$icemelon = Array('ice' => 'melon', 'foo' => 'fighters');
array2vars($icemelon);
echo "$ice, $foo "; // outputs: melon, fighters
?>

Example 2.

<?php
$q = mysql_query($query);
while($row = mysql_fetch_array($q)) {
    array2vars($row);
    // use variables
    // ....
}
?>

Source Code

<?php
function array2vars($arr) {
    foreach($arr AS $key=>$var) {
        global $$key;
        $$key = $var;
    }
}
?>
