If you need the first or last entry of an array, then this could help you.
<?php
function array_last_entry($arr){
if(!is_array($arr))
return;
if(empty($arr))
return;
return end($arr);
}
function array_first_entry($arr){
if(!is_array($arr))
return;
if(empty($arr))
return;
reset($arr);
return current($arr);
}
$arr = array( '5' => 'five', '3' => 'three', '8' => 'eight',);
echo 'last entry: '.array_last_entry($arr).'<br>';
echo 'first entry: '.array_first_entry($arr).'<br>';
echo 'alternative output:<br>';
echo 'last entry: '.$arr[count($arr)-1];
echo '<br>first entry: '.$arr[0];
?>
The output will look like:
last entry: eight
first entry: five
alternative output:
last entry:
first entry:
As you can see, if you have to handle arrays with non-continuous indexes, these functions may be very helpful.
