The escapeshellcmd function is a built-in PHP function that is enabled by default in most PHP installations. This function is used to escape special characters in a string that is going to be passed to a shell command. It is an important security function that helps prevent shell injection attacks.

However, if you don't have access to the server configuration and you cannot enable this function, there are other ways to prevent shell injection attacks. One way is to use the escapeshellarg function instead, which is also a built-in PHP function and is generally available on most servers. This function can be used to escape arguments passed to a shell command.

Another approach is to use a shell command wrapper library such as Symfony Process or Symfony Console, which provide a more secure way to execute shell commands by handling the escaping and parameterization of command arguments automatically.
