Return value

array

Performance profile

How much work a call to WP_Plugin_Install_List_Table::get_installed_plugins() 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 stored settings via get_site_option(), cached per request but not free on a cold cache.

Scaling

Scales with input

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

Instructions

10–18

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

Plugin surface

None

Nothing here hands control to plugin code.

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

What one call costs · 1 distinct outcome

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