Synopsis:

$strip(<chars> <text>)
$pass(<chars> <text>)

Technical:

  • The <chars> argument is a dword. This is different than most functions.
  • If the <text> argument is omitted the empty string is returned.
  • The return value for $strip() is a copy of <text> from which every instance of any character in <chars> has been removed.
  • The return value for $pass() is a copy of <text> from which every instance of any character not in <chars> has been removed.

Practical:

These functions can be useful to remove dangerous or unwanted characters from a text string.

Returns:

$strip(): <text> with all of the characters in <chars> removed.
$pass(): <text> with all of the characters not in <chars> removed.

Examples:

$strip(aeoiu hello there)            returns "hll thr"
$pass(aeoiu hello there)             returns "eoee"

History:

This function originally appeared in ircII-2.1.5
