Been searching the PHP documentation and this doesn't seem possible but wanted to check.
Say I have a function like this:
class Utils {
static function doSomething( Array $input ){
...
}
}
Is is possible to use a inbuilt PHP function like is_callable
to check if both the function exists and if the variable I have will be accepted by the type definition in the function.
So:
$varA = array( 'a', 'b', 'c' );
$varB = 'some string';
$functionToCall = array( 'Utils', 'doSomething' );
is_callable( $functionToCall, $varA ) => true;
is_callable( $functionToCall, $varB ) => false;
Of course is_callable
cannot be used like this. But can it be done without using a Try Catch?
If not would this be the best way around it?
try {
Utils::doSomething( 10 )
} catch (TypeError $e) {
// react here
}
Thanks!
