WP_List_Table::get_primary_column_aria_label( object|array $item ): string

Since
7.1.0
Source
wp-admin/includes/class-wp-list-table.php:1792
Returns a clean, human-readable label for the primary column's row header.

Description

Used as the aria-label attribute value on the <th scope="row"> element, giving screen readers a concise cell name instead of computing it from the full cell content (which may include row action links, excerpts, etc.).

Subclasses should override this method to return the item's primary identifier (e.g. post title, plugin name, username). Return an empty string to omit the attribute.

Performance profile

How much work a call to WP_List_Table::get_primary_column_aria_label() 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
Trivial

Touches nothing outside its own arguments.

Scaling
Constant

No loop in the body: the same number of instructions runs whatever you pass in.

Instructions
2

Executed per call on PHP 8.5. The body compiles to 2.

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 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_List_Table::get_primary_column_aria_label() can have, taken from its control-flow graph on PHP 8.5.

WhenInstructionsCalls it makes
always2none

Across PHP versions

Compiles the same on PHP 7.4, 8.1, 8.2, 8.3, 8.4, 8.5 and 8.6-dev: 2 instructions, 2 executed per call, 0 branches. The work does not change between versions.

An instruction is not a fixed amount of time, so a matching count is not necessarily the same speed; what it rules out is a difference in the work itself.
