[SOLVED] array strtolower

[homer.favenir]

hi,

can anyone please help me how to change the case of an array to lower.

 

my script is

<?php
$a = array(cot01,COT02,cot03);
$b = array(cot01,COT02,COT03);
$diff = array_diff($a, $b);
$diff2 = array_diff($b, $a);
$union =  array_merge($diff,$diff2);
print_r($union);

?>

 

i want to strtolower the $a and $b, when i compare them the uppercase is different

from lowercase eventhough they have the same word

 

thanks

$a = array_map('strtolower', $a);
$b = array_map('strtolower', $b);

<?php

$a = array(cot01,COT02,cot03);
$b = array(cot01,COT02,COT03);
$a = array_map('strtolower', $a);
$b = array_map('strtolower', $b);
$a=array_diff($a,$b);
$union = array_merge($a,$b);
print_r($union);

?>

 

 

array array_map  ( callback $callback  , array $arr1  [, array $...  ] )

 

array_map() returns an array containing all the elements of arr1 after applying the callback function to each one. The number of parameters that the callback function accepts should match the number of arrays passed to the array_map()

 

 

Array

(

    [0] => cot01

    [1] => cot02

    [2] => cot03

)
