replacing backslash string in php

Question

I need to replace \\b with \\\\b in php in order to insert into mysql table.

Therefore \\bhello\\b becomes \\\\bhello\\\\b then inserted into mysql where it is converted back to \\bhello\\b.

But I can't seem to figure out how. Tried preg_replace and str_replace and I always end up with an error or what I started with.

Sounds like you need to use the correct escaping mechanism for your database.

For the record, this is definitely not addslashes() .

If using mysql_*() , then use mysql_real_escape_string() .

If using PDO , use bound parameters with prepared statements.
