Question

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

Parses the plugin contents to retrieve plugin’s metadata.

---

description

The metadata of the plugin’s data searches for the following in the plugin’s header. All plugin data must be on its own line. For plugin description, it must not have any newlines or only parts of the description will be displayed and the same goes for the plugin data. The below is formatted for printing.

/*
Plugin Name: Name of Plugin
Plugin URI: Link to plugin information
description: Plugin description
Author: Plugin author's name
Author URI: Link to the author's web site
Version: Must be set in the plugin for WordPress 2.3+
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.
 * /

Some users have issues with opening large files and manipulating the contents for want is usually the first 1kiB or 2kiB. This function stops pulling in the plugin contents when it has all of the required plugin data.

The first 8kiB of the file will be pulled in and if the plugin data is not within that first 8kiB, 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.

   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.
