WP_CLI::runcommand │ public static │ WP-CLI 1.0

Run a WP-CLI command.

Launches a new child process to run a specified WP-CLI command. Optionally:

• Run the command in an existing process.
• Prevent halting script execution on error.
• Capture and return STDOUT, or full details about command execution.
• Parse JSON output if the command rendered it.
• Include additional arguments that are passed to the command.

$options = array(
  'return'       => true,                // Return 'STDOUT'; use 'all' for full object.
  'parse'        => 'json',              // Parse captured STDOUT to JSON array.
  'launch'       => false,               // Reuse the current process.
  'exit_error'   => true,                // Halt script execution on error.
  'command_args' => [ '--skip-themes' ], // Additional arguments to be passed to the $command.
);
$plugins = WP_CLI::runcommand( 'plugin list --format=json', $options );
