Code Inspection: Parameter type

Reports the parameters passed to a function call, whose types do not match the ones specified in the function definition via type declaration or the PHPDoc @param tag.

See Type declarations (php.net) and @param (phpdoc.org) for details.

In the following example, the expectArray() function has the parameter of the array type but is called with a string argument.

/**
 * @param array $arr
 * @return array
 */
function expectArray(array $arr) {
    return $arr;
}
expectArray("Foo");
