+ | ======Synopsis:====== | ||
+ | $__strlen__(<string>) | ||
+ | |||
+ | ======Technical:====== | ||
+ | This function is used to determine the length, in characters, of a given | ||

+ | This function is effectively the same as the $@var notation, except that | ||

+ | |||
+ | ======Returns:====== | ||
+ | | >0 | number of characters in string | | ||
+ | | 0 | no string given | | ||
+ | |||
+ | ======Examples:====== | ||
+ | <file> | ||
+ | $strlen($1-3) returns length of args $1 to $3 | ||
+ | $strlen(epic is cool) returns "12" | ||
+ | </file> | ||
