Question

Here is my array:

print_r($mCOneC);

=> Array ( [0] => start [1] => Trial [2] => Refusal [3] => Expel [4] => Mouth Clean )

If I do:

$length = count( array_keys( $mCOneC, 'start' ));

echo $length;

I get: 1

If I do:

$length = count( array_keys( $mCOneC, 'Trial' ));

echo $length;

I get: 0

Any reason why this is not working?

Answer 1

Simple you are dealing with space

$mCOneC = Array(
        0 => "start",
        1 => "Trial ",
        2 => "Refusal",
        3 => "Expel",
        4 => "Mouth Clean");


$mCOneC = array_map("trim", $mCOneC); <------------- Fix Spaces
$length = count( array_keys( $mCOneC, 'start' ));
var_dump($length);


$length = count( array_keys( $mCOneC, 'Trial' ));
var_dump($length);
