I`m using $_POST array with results of checkbox's selected from a form.
I'm thinking of using php in_array
function but how could I extract only values that start with chk Given the following array:
Array (
[chk0] => 23934567622639616
[chk3] => 23934567622639618
[chk4] => 23934567622639619
[select-all] => on
[process] => Process
)
Simple and fast
$result=array();
foreach($_POST as $key => $value){
if(substr($key, 0, 2) == 'chk'){
$result[$key] = $value;
}
}
