The values are concatenated from left to right, in the | | order that they were specified. | | NOTE: The first argument for push() must be a variable and not a | | literal value. All other arguments may be literal values. | | | | USAGE EXAMPLE: | | $string = "Humpty Dumpty sat on a wall.\n"; | | $string_2 = "Humpty Dumpty had a great fall.\n"; | | $length = str::push ($string, $string_2); | | print $length; // Contains 61 | | print $string; // Contains $string . $string_2 | | | | str::shift() method | | ------------------- | | Strip the leftmost character from a scalar variable and return the | | character. | | NOTE: shift() must be used on a variable and not a literal value. | | | | USAGE EXAMPLE: | | $string = "Humpty Dumpty sat on a wall."; | | $chr = str::shift ($string); | | print $chr; // Contains "H" | | print $string; // Contains "umpty Dumpty sat on a wall." | | | | str::unshift() method | | ------------------ | | Join one or more scalar values onto the left end of a scalar | | variable. The values are concatenated from right to left, in the | | order that they were specified. | | NOTE: The first argument for unshift() must be a variable and not a | | literal value. All other arguments may be literal values. | | | | USAGE EXAMPLE: | | $string = 'fe'; | | $length = str::unshift ($string, 'fi', 'fo', 'foo'); | | print $length; // Contains 9 | | print $string; // Contains "foofofife" | +----------------------------------------------------------------------+ +----------------------------------------------------------------------+ | CVS LOG INFO | +----------------------------------------------------------------------+ $Log: str.pkg,v $ Revision 1.3 2001/01/02 03:56:14 zak Added tests to handle empty strings for pop and shift. $Log: str.pkg,v $ Revision 1.2 2000/11/24 02:08:04 zak Simplified code for push and unshift.
