php preg_replace problem

[sven]

im having a problem, it seems that when i do a preg replace for ".", it changes all the letters in the string, anyone know of a way to change the period to a sertain text without this problem?

thanks, any code will work

simply add a \ before the . so it looks like "\." . equals any character so it needs to be escaped
