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

## 説明

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: . \ + * ? [ ^ ] $ ( ) { } = ! <`` > | : -

## 戻り値

Returns the quoted string.
