WP_Posts_List_Table::column_title( WP_Post $post )

Compatibility

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

Parameters

$postWP_Post

The current WP_Post object.

Performance profile

How much work a call to WP_Posts_List_Table::column_title() 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

Scales with input

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

Instructions

46–169

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 198.

Plugin surface

2 hooks

Third-party callbacks on 'the_title', 'quick_edit_enabled_for_post_type' 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

• querycontent queryget_post()called directly
• hookthird-party callbacksapply_filters()called directly
• optionoption read or writeget_option()one call below WP_Posts_List_Table::column_title()
• cacheobject cachewp_cache_add()one call below WP_Posts_List_Table::column_title()

Further down the call graph this can also reach 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 · 192 distinct outcomes

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