Be careful comparing ReflectionParameter::getType() and gettype() as they will not return the same results for a given type.
string - string // OK
int - integer // Type mismatch
bool - boolean // Type mismatch
array - array // OK
(PHP 4, PHP 5, PHP 7, PHP 8)
gettype — Get the type of a variable
Returns the type of the PHP variable value
. For
type checking, use is_*
functions.
value
The variable being type checked.
Possible values for the returned string are:
"boolean"
"integer"
"double"
(for historical reasons "double"
is
returned in case of a float, and not simply
"float"
)
"string"
"array"
"object"
"resource"
"resource (closed)"
as of PHP 7.2.0
"NULL"
"unknown type"
Version | Description |

Previously the returned value for closed resources were 'unknown type' .

Example #1 gettype() example
<?php
$data = array(1, 1., NULL, new stdClass, 'foo');
foreach ($data as $value) {
echo gettype($value), "\n";
}
?>
The above example will output something similar to:
integer double NULL object string
