Fix: Switch to Linux 😃 sorry, couldn't resist
I suspect these articles are stored in a database? Sometimes, I've found the best bet is to replace them on storage, and replace them coming out...
//on insert, do a str_replace to put a holder for them
<?
$string = "C:\Program Files\Somewhere\Someplace";
$newString = str_replace("\\(actually two slashes here)","[slash]",$string);
//should return "C:[slash]Program Files[slash]Somewhere[slash]Someplace"
//Now on the way out....
$string = "C:[slash]Program Files[slash]Somewhere[slash]Someplace";
$newString = str_replace("[string]","\\(actually two slashes here)",$string);
?>
Kinda a workaround...but effective...
