strtolower

[etsted]

$haystack = array("gif");$fileParts = array("extension" =>"GIF", nr2 => "JPG");$fileParts = $fileParts['extension'];$fileParts = strtolower($fileParts[0]);if(in_array($fileParts, $haystack)){ echo "right";} else { echo "false";}

 

this returns false, how can i make it return true?

 

in real life, the $fileParts array is acctaully $_FILES['fileName']['name'], where i try to make the extension into lower case before the array check

$fileParts is a string, so if you put [0] on it you'll only get the first letter of the string when passing it to strtolower()
