WP_Debug_Data::get_wp_media(): array<string,

Compatibility

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

Return value

array<string,

string|array> The media handling debug data.

Performance profile

How much work a call to WP_Debug_Data::get_wp_media() 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

Moderate

Only touches the object cache, via wp_cache_get().

Scaling

Scales with input

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

Instructions

194–213

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 487.

Plugin surface

None

Nothing here hands control to plugin code.

Called by

1

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

What it touches

• hookthird-party callbacksapply_filters()one call below WP_Debug_Data::get_wp_media()
• cacheobject cachewp_cache_get()one call below WP_Debug_Data::get_wp_media()

Further down the call graph this can also reach query, option, 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 · 8 distinct outcomes

One number would be a lie: the work depends on which branch runs. These are every distinct cost WP_Debug_Data::get_wp_media() 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.
