wp_get_original_image_path( int $attachment_id, bool $unfiltered = false ): string|false

Since
5.3.0, 5.4.0
Source
wp-includes/post.php:8683
Retrieves the path to an uploaded image file.

Description

Similar to get_attached_file() however some images may have been processed after uploading to make them suitable for web use. In this case the attached "full" size file is usually replaced with a scaled down version of the original image. This function always returns the path to the originally uploaded image file.

Performance profile

How much work a call to wp_get_original_image_path() 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

Reaches the database via get_post().

Scaling
Constant

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

Instructions
7–31

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 34.

Plugin surface
1 hook

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

7

7 places in core call this, so the cost is paid more often than your own code shows.

What it touches

  • hookthird-party callbacksapply_filters()called directly
  • querycontent queryget_post()one call below wp_get_original_image_path()

Further down the call graph this can also reach cache, serialize, option 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 · 3 distinct outcomes

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

An instruction is not a fixed amount of time, so a matching count is not necessarily the same speed; what it rules out is a difference in the work itself.
