preg_quote
PREG_QUOTE(3) 1 PREG_QUOTE(3)preg_quote - Quote regular expression charactersSYNOPSIS
string preg_quote NULL (string $str, [string $delimiter])
DESCRIPTION preg_quote(3) 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: . + * ? [ ^ ] $ ( ) { } = ! < > | : -
PARAMETERS
o $str
- The input string.
o $delimiter
- If the optional $delimiter is specified, it will also be escaped. This is useful for escaping the delimiter that is required by
the PCRE functions. The / is the most commonly used delimiter.
RETURN VALUES
Returns the quoted (escaped) string.
