Dear readers, I present some of the most useful functions to operate on arrays.
Please, comment :)
Finding all keys of an array
<?php
$myArray=array(1=>"em"),6=>"value";
array_keys($myArray); //returns array(1,6)
?>
Running through all values of an array
<?php
$myFriends=array('Mike','Jake','Helen');
foreach($myFriends as $friend){
echo $friend . ' is my friend <br>';
}
?>
Some of the more obvious ones.
Checking if an array is empty
<?php
$Arr = array('value');
