The below is an example for removing the first element from an associative array $a.
<html> <body> <?php $a=array("color1"=>"red","color2"=>"green","color3"=>"blue","color4"=>"yellow"); array_pop($a); print_r($a); ?> </body> </html>
Output: Array ( [color1] => red [color2] => green [color3] => blue )
This program is using an associative array $a, which is containing 4 elements firstly. After the deletion of the first element using the function array_pop(), the associative array $a is containing 3 elements and print the associative array $a using the predefined function print_r().
