Array with meta data, or false when the meta table is not installed.

Performance profile

How much work a call to has_term_meta() 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_results().

Scaling
Constant

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

Instructions
8–22

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 23.

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 it touches

  • sqldatabase query->get_results()called directly
  • optionoption read or writeget_option()one call below has_term_meta()

Further down the call graph this can also reach hook, 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 · 2 distinct outcomes

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

WhenInstructionsCalls it makes
$check !== null8wp_check_term_meta_support_prefilter()
$check === null22wp_check_term_meta_support_prefilter(), ->prepare(), ->get_results()

Across PHP versions

Compiles the same on PHP 7.4, 8.1, 8.2, 8.3, 8.4, 8.5 and 8.6-dev: 23 instructions, 8–22 executed per call, 1 branch. 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.

Generated from the wordpress-develop 6.9.7 tag, from src/wp-includes/taxonomy.php, and regenerated for each WordPress release so it tracks the code rather than a snapshot of it.
