attachment_submitbox_metadata()

Compatibility

Present in every tracked release (6.7.7 to 7.1.0), and compiles on PHP 7.4 through 8.6-dev.

Performance profile

How much work a call to attachment_submitbox_metadata() 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

Heavy

Reads or writes the filesystem via file_exists().

Scaling

Scales with input

The body loops, so the work grows with how much data it finds.

Instructions

128–232

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 402.

Plugin surface

3 hooks

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

Called by

0

Nothing in core calls this; the cost is only what you spend yourself.

What it touches

• querycontent queryget_post()called directly
• hookthird-party callbacksapply_filters()called directly
• filesystemfilesystem accessfile_exists()called directly

Further down the call graph this can also reach option, cache, serialize and transient. Those are the worst case, several calls deep and usually down an error path, not what a normal call pays.

What one call costs · 144 distinct outcomes

One number would be a lie: the work depends on which branch runs. These are every distinct cost attachment_submitbox_metadata() can have, taken from its control-flow graph on PHP 8.5.

This body has more branch combinations than are worth enumerating, so the table covers the outcomes found first rather than every one that exists.
