PHP Syntax: Iterate over an Associative Array

Posted December 27, 2003 by Quinn McHenry in PHP programming

An associative array stores an arbitrary index in addition to the values. This is useful for storing configuration information such as in the $_SERVER array.


An individual element of this array can be retrieved with the following:

$_SERVER['SITE_HTMLROOT']

To loop through all of the elements in $_SERVER and display the values and their corresponding indexes, use the following:

foreach ( $_SERVER as $ind=>$val )
echo "$ind : $val
";
