I don't know if this is by design or not, but in_array() does not work with associative hashes:
<?php
$Test = Array("my_var" => 2);
print_r($Test);
echo "\n";
var_dump(in_array("my_var", $Test));
?>
Outputs:
Array
(
[my_var] => 2
)
bool(false)
The workaround is to use array_key_exists() instead:
<?php
$Test = Array("my_var" => 2);
print_r($Test);
echo "\n";
var_dump(array_key_exists("my_var", $Test));
?>
Outputs:
Array
(
[my_var] => 2
)
bool(true)
