get_editable_roles(): array[]

Since
2.8.0
Source
wp-admin/includes/user.php:274
Fetch a filtered list of user roles that the current user is allowed to edit.

Description

Simple function whose main purpose is to allow filtering of the list of roles in the $wp_roles object so that plugins can remove inappropriate ones depending on the situation or user making edits.
Specifically because without filtering anyone with the edit_users capability can edit others to be administrators, even if they are only editors or authors. This filter allows admins to delegate user management.

Return value

array[]
Array of arrays containing role information.

Performance profile

How much work a call to get_editable_roles() 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
9

Executed per call on PHP 8.5. The body compiles to 9.

Plugin surface
1 hook

Third-party callbacks on 'editable_roles' run inside this call, and their cost is not bounded by anything here.

Called by
5

5 places 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 get_editable_roles() can have, taken from its control-flow graph on PHP 8.5.

WhenInstructionsCalls it makes
always9wp_roles(), apply_filters()

Across PHP versions

Compiles the same on PHP 7.4, 8.1, 8.2, 8.3, 8.4, 8.5 and 8.6-dev: 9 instructions, 9 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.

Hooks and filters fired · 1

One hook fires while get_editable_roles() runs, in this order:

  1. apply_filters( editable_roles )filterline 284 (+10 into the body)
