get_plugin_data( string $plugin_file, bool $markup = true, bool $translate = true ): array
Parses the plugin contents to retrieve plugin’s metadata.
Contents
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
load_plugin_textdomain().
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.
* / # Remove the space to close comment.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.

Feedback
Another alternative (depending on circumstances) could be to use
get_file_data()instead. It’s the same function as used byget_plugin_data(), but without the ‘bells and whistles’. And becauseget_file_data()lives inwp-includes/functions.php, there is no need to includewp-admin/includes/plugin.phpon non-admin screens. — By Bart Kuijper —Warning:
get_plugin_data(..)is NOT available by default (not even in the admin). The pattern proposed by Aamer Shahzad withif ( ! function_exists( 'get_plugin_data' ) ) { require_once ... }seems to be mandatory before usingget_plugin_data(..)(although not documented).Otherwise, the whole site may crash with a fatal PHP error “call to undefined function”.
