escapeshellcmd() & escapeshellarg():
These functions will escape any characters in a string that might be used to trick a shell command into executing arbitrary commands. These functions shall be used to make sure that any data coming from user input is escaped before this data is passed to the exec() or system() functions, or to the backtick operator.
Example:
system('ls '.escapeshellarg($dir));
