How can PHP remove all instances of the above snippet in a page without requiring escaping the above string. Or, how can I easily get the escape-string of the above in order to plug into a preg_replace to remove it.

I need to run PHP on the server against a bunch of htm files. It must be done on the server-side in one operation.

Answer 1

You could escape your search string with preg_quote :

 string preg_quote ( string $str [, string $delimiter = NULL ] ) 

preg_quote() takes str and puts a backslash in front of every character that is part of the regular expression syntax. This is useful if you have a run-time string that you need to match in some text and the string may contain special regex characters.

The special regular expression characters are: . \\ + * ? [ ^ ] $ ( ) { } = ! < > | : - . \\ + * ? [ ^ ] $ ( ) { } = ! < > | : -
