Pretty straightforward; I can\'t seem to find anything definitive regarding PHP\'s preg_replace() supporting named backreferences:
I want to add a character to the end of each file extension found in a body of text usi开发者_如何学编程ng preg_replace().
I\'m trying to open a file, match a particular line, and then wrap HTML tags around that line. Seems terribly simple but apparently I\'m missing something and don\'t understand the Perl matched patter

I have strings in the form \\d+_开发者_如何学C\\d+ and I want to add 1 to the second number. Since my explanation is so very clear, let me give you a few examples:
MySQL manual is not very detailed about what expressions it supports, so I am not sure if the following is possible with MySQL at all.
string.replace(/([\\开发者_如何学Pythont])/g,\"\\\\$1\") is working fine where string.replace(/([\\n])/g,\"\\\\$1\")
Is there a way to modify the value of a backreference? Example: In the following Text \"this is a test\"
I have a string, say r\"a\". I want to replace every r\"a\" with the string r\"\\1\", but my regex engine does not understand this.
In Java, and it seems in a few other languages, backreferences in the pattern are preceded by a backslash (e.g. \\1, \\2, \\3, etc), but in a replacement string they preceded by a dollar sign (e.g. $1
