Many times we store our data in array and need to perform some additional function to the array like strtolower, strtoupper, and etc. Before i get to know this handy function, I’ve been searching for the shortest code to perform strtolower to an array in php. Thank god, finally i found array_map function and it solved my many years problem.
To strtolower an array in php, use the code below:-
Advertisements
$myarray = array('XyZ', 'AbC', 'EFG');
$myarray = array_map('strtolower', $myarray);
