Tips and Notes
Note: If the keys are numeric, all elements will get new keys, starting from 0 and increases by 1. (See example 2)
Example 1

$a=array("a"=>"Dog","b"=>"Cat","c"=>"Horse");
echo array_shift($a);
print_r ($a);
?>
$a=array("a"=>"Dog","b"=>"Cat","c"=>"Horse");
echo array_shift($a);
print_r ($a);
?>
The output of the code above will be:
Dog
Array ( [b] => Cat [c] => Horse )
Array ( [b] => Cat [c] => Horse )
Example 2
With numeric keys:
<?php
$a=array(0=>"Dog",1=>"Cat",2=>"Horse");
echo array_shift($a);
print_r ($a);
?>
$a=array(0=>"Dog",1=>"Cat",2=>"Horse");
echo array_shift($a);
print_r ($a);
?>
The output of the code above will be:
Dog
Array ( [0] => Cat [1] => Horse )
Array ( [0] => Cat [1] => Horse )
