array_change_key_case () is an another PHP prebuilt / default array function, This function is basically allows user to do the array keys lower or uppercase. It will rturn null and will Throw E_WARNING if array is not an array.
Syntax of array_change_key_case () :
array_change_key_case(array, case)
array (required) : It is the array for which we need to change the case.
case (optional) : this needs to be passed like CASE_UPPER or CASE_LOWER, if not pass any ‘case’ it will return CASE_LOWER.
Example 1 :
<?php
$salary = array("MonI" =>"10000", "SoNu"=>"15000", "PrAkHar"=>"45000");
print_r(array_change_key_case($salary,CASE_UPPER));
?>
Output will be :
Array ( [MONI] => 10000 [SONU] => 15000 [PRAKHAR] => 45000 )
Example 2 :
<?php
// PHP code to describe array_change_key_case()
function change_case($array_value){
return(array_change_key_case($array_value, CASE_LOWER));
}
$array_change = array("RoHIT" => 45, "RaHuL" => 30, "SaRITA" => 29, "RaKUL" => 55, "KaNAV" => 10);
print_r(change_case($array_change));
?>
Output will be :
Array ( [rohit] => 45 [rahul] => 30 [sarita] => 29 [rakul] => 55 [kanav] => 10 )
