I think that this sentence in documentation is too short. I found excerpt in PCRE documentation (http://www.pcre.org/pcre.txt) that extends above sentence. "In other words, the parentheses that are referenced need not be to the left of the reference for numbers less than 10. A "forward back reference" of this type can make sense when a repetition is involved and the subpattern to the right has participated in an earlier iteration. It is not possible to have a numerical "forward back reference" to a subpattern whose number is 10 or more using this syntax because a sequence such as \50 is interpreted as a character defined in octal." In my opinion the extended sentence is better to understand. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52066&edit=1
