.\"replace all instances of a string within a string .DT replace_string Discworld driver help replace_string Name .SI 5 replace_string() - replace all instances of a string within a string .EI Synopsis .SI 5 string replace_string( string str, string pattern, string replace ); .EI Description .SP 5 5 replace_string() returns str with all instances of pattern replaced with replace. If pattern has zero length then str is returned unmodified. If the resultant string would exceed the maximum string length then replace_string() returns an undefinedp(), non-stringp() value. replace_string() can be used to remove characters from a string by specifying a pattern and a zero-length replace parameter. For example, replace_string(" 1 2 3 ", " ", "") would return "123". replace_string() executes faster this way then explode()/implode(). .EP See also .SI 5 extract(3), sscanf(3), explode(3) .EI
