1.2.618. Is_A() With String¶
When using is_a() with a string as first argument, the third argument is compulsory. The third argument is
$allow_string, and is necessary to work on strings.
<?php
// is_a() works with string as first argument, when the third argument is 'true'
if (is_a('A', 'B', true)) {}
// is_a() works with object as first argument
if (is_a(new A, 'A')) {}
?>
See also is_a.
