note 129489 added to function.gettype

Since ReflectionParameter::getType() and gettype() do not return the same type name, you can leverage the strpos() function. use DateTime; use ReflectionClass; $myVar = 45; # get the type of your variable $varType = gettype($myVar); $cls = new ReflectionClass(DateTime::class); $mth = $cls->getMethod('setDate'); $params = $mth->getParameters(); foreach($params as $param) {     $paramTypes = $param instanceof ReflectionUnionType     ? $param->getTypes()     : [$param];     foreach($paramTypes as $paramType) {         if (strpos($paramType, $varType) >= 0) {             echo "Parameter '". $paramType->getName() ."' has type '". $paramType->getType() ."' which matches the variable's type of '$varType'.\n";         }     } } ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.13.131 (proxied: 109.165.232.194) ---- Manual Page -- https://php.net/manual/en/function.gettype.php Edit -- https://main.php.net/note/edit/129489 Del: integrated -- https://main.php.net/note/delete/129489/integrated Del: useless -- https://main.php.net/note/delete/129489/useless Del: bad code -- https://main.php.net/note/delete/129489/bad+code Del: spam -- https://main.php.net/note/delete/129489/spam Del: non-english -- https://main.php.net/note/delete/129489/non-english Del: in docs -- https://main.php.net/note/delete/129489/in+docs Del: other reasons-- https://main.php.net/note/delete/129489 Reject -- https://main.php.net/note/reject/129489 Search -- https://main.php.net/manage/user-notes.php
