Syntax Syntax

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

Description Description

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.
