Finfo Moved Away From Resource¶
Finfo functions have moved from resource to objects in PHP 8.1. Instead of returning a resource, it now returns a finfo object. Checks based on is_resource() must be upgraded, and are now dead code.
PHP code¶
<?php
var_dump(finfo_open());
?>
Before¶
resource(4) of type (file_info)
After¶
object(finfo)#1 (0) {
}
PHP version change¶
This behavior changed in 8.1
