示例1: wfShellExec

/**
 * Execute a shell command, with time and memory limits mirrored from the PHP
 * configuration if supported.
 *
 * @param string|string[] $cmd If string, a properly shell-escaped command line,
 *   or an array of unescaped arguments, in which case each value will be escaped
 *   Example:   [ 'convert', '-font', 'font name' ] would produce "'convert' '-font' 'font name'"
 * @param null|mixed &$retval Optional, will receive the program's exit code.
 *   (non-zero is usually failure). If there is an error from
 *   read, select, or proc_open(), this will be set to -1.
 * @param array $environ Optional environment variables which should be
 *   added to the executed command environment.
 * @param array $limits Optional array with limits(filesize, memory, time, walltime)
 *   this overwrites the global wgMaxShell* limits.
 * @param array $options Array of options:
 *   - duplicateStderr: Set this to true to duplicate stderr to stdout,
 *     including errors from limit.sh
 *   - profileMethod: By default this function will profile based on the calling
 *     method. Set this to a string for an alternative method to profile from
 *
 * @return string Collected stdout as a string
