In PHP use preg_replace (http://php.net/preg_replace for details)

In PostgreSQL use replace(string text, from text, to text)

(http://www.postgresql.org/docs/
view.php?version=7.3&idoc=1&file=functions-string.html)

To update a column in a table, you could do something like:

UPDATE table SET column = REPLACE( column, ' ', '_' );

For something like this str_replace is easier to use and generally faster.
