So I have this MySQL database and a table and in the rows there a lot of \",\" in them, and I wish when they are output on the screen with PHP to be switched to \"\" inste
Assuming there are no CSV quoting issues:
$newStr = str_replace( ',', '', $string );
EDIT:
After seeing your rollback, i see that you actually want to replace the , with a newline character such as \r, \n or \r\n:
,
newline
\r
\n
\r\n
$newStr = str_replace( ',', "\n", $string );
