get_plugin_data( string $plugin_file, bool $markup = true, bool $translate = true ): array

Parses the plugin contents to retrieve plugin’s metadata.


All plugin headers must be on their own line. Plugin description must not have any newlines, otherwise only parts of the description will be displayed.
The below is formatted for printing.

Plugin Name: Name of the plugin.
Plugin URI: The home page of the plugin.
Description: Plugin description.
Author: Plugin author's name.
Author URI: Link to the author's website.
Version: Plugin version.
Text Domain: Optional. Unique identifier, should be same as the one used in
Domain Path: Optional. Only useful if the translations are located in a
     folder above the plugin's base path. For example, if .mo files are
     located in the locale folder then Domain Path will be "/locale/" and
     must have the first slash. Defaults to the base folder the plugin is
     located in.
Network: Optional. Specify "Network: true" to require that a plugin is activated
     across all sites in an installation. This will prevent a plugin from being
     activated on a single site when Multisite is enabled.
Requires at least: Optional. Specify the minimum required WordPress version.
Requires PHP: Optional. Specify the minimum required PHP version.

The first 8 KB of the file will be pulled in and if the plugin data is not within that first 8 KB, then the plugin author should correct their plugin and move the plugin data headers to the top.

The plugin file is assumed to have permissions to allow for scripts to read the file. This is not checked however and the file is only opened for reading.


Absolute path to the main plugin file.

User Contributed Notes

  1. Skip to note 5 content

    If $markup or $translate are set to true (as they are by default), the function indirectly calls wptexturize, potentially breaking other plugins if this happens before the init hook.

  2. Skip to note 6 content

    Warning: get_plugin_data(..) is NOT available by default (not even in the admin). The pattern proposed by Aamer Shahzad with if ( ! function_exists( 'get_plugin_data' ) ) { require_once ... } seems to be mandatory before using get_plugin_data(..) (although not documented).

    Otherwise, the whole site may crash with a fatal PHP error “call to undefined function”.
