Question

It seems to be simple, but I have problem.

ereg_replace("\n","\\n",$row)

into preg_replace.

Anyone could give me a hand?

Answer 1

The only thing you need to change (except function name) is to add delimiters to the pattern (slashes in this case):

preg_replace("/\n/", "\\n", $row);

However, in this particular case you do not need to use regexes (which are slow enough), simple str_replace would be fine:

str_replace("\n", "\\n", $row);
