string_confine_length

By Daniel · January 7, 2009

Trims characters from the end of a string until it is no longer than max_length. If trimming is necessary, the suffix (typically "...") will be appended on to the end of the string.

 * Trims characters from the end of a string until it is no longer than
 * max_length. If trimming is necessary, the suffix (typically "...") will
 * be appended on to the end of the string.
 *
 * If count_suffix is true, the suffix will be counted toward the length of
 * the string.

if (string_length(argument0) <= argument1)
  return argument0;

return string_copy(argument0, 1, argument1 - argument3 * string_length(argument2)) + argument2;
