Performance profile

How much work a call to WP_Fatal_Error_Handler::should_handle_error() does, and what it touches: the algorithmic scaling, the Zend instruction count per call across PHP versions, the hooks it hands control to, and the core code that calls it. Measured from the compiled opcodes, not a stopwatch, so every number is identical on any machine running the same PHP version, and every function in core is ranked by cost.

Cost class

Trivial

Touches nothing outside its own arguments.

Scaling

Constant

No loop in the body: the same number of instructions runs whatever you pass in.

Instructions

7–13

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 14.

Plugin surface

1 hook

Third-party callbacks on 'wp_should_handle_php_error' run inside this call, and their cost is not bounded by anything here.

Called by
