WP_Plugins_List_Table::single_row( array $item )

Compatibility

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

Parameters

$itemarray

Performance profile

How much work a call to WP_Plugins_List_Table::single_row() 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 what you pass in.

Instructions

192–255

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 1296.

Plugin surface

10 hooks

Third-party callbacks on 'network_admin_plugin_action_links', 'network_admin_plugin_action_links_{$plugin_file}', 'plugin_action_links' run inside this call, and their cost is not bounded by anything here.

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()called directly
• optionnetwork optionget_site_option()called directly

Further down the call graph this can also reach cache, serialize, query 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 · 24 distinct outcomes

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