Performance profile

How much work a call to WP_Dependencies::all_deps() 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

Light

Touches nothing outside its own arguments.

Scaling

Scales with input

The body loops, so the work grows with what you pass in.

Instructions

7–87

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 117.

Plugin surface

None

Nothing here hands control to plugin code.

Called by

4

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

What it touches

• hookthird-party callbacksdo_action()one call below WP_Dependencies::all_deps()

Further down the call graph this can also reach query, 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 · 7 distinct outcomes

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