Can I bulk fix PHP require/include references?
A pal of mine asks: "Ugh.. I'm facing server-move Hades.. am moving my site dadsrights.org to a hosted solution, and I have dozens and dozens of files with PHP require_once() includes like "/www/dadsrights/XX". They all need to be changed to "/nfs/www/dadsrights.org/XX". Help!!"
Annie, I am sure we can solve this by having you log in to their Unix server and running a simple script. This is, in fact, a perfect job for the Unix stream editor sed, which accepts patterns of the form s/old/new/g to replace all occurrences of "old" with "new". (the trailing 'g' applies it globally, meaning more than once in a single line, if applicable)
But before we do this, it's always smart to back up all the files we're about to tweak. Just in case. :-) To do that, run this command:
$ tar czvf php-file-backup.tgz ./*.phpThis will create a new file called "php-file-backup.tgz" that's a compressed 'tar' archive of all the files. If something goes south and things don't work, you can always unpack and restore all the PHP files with tar xzf php-file-backup.tgz).
Now, ready for some shell script programming? Open up an editor (vi, pico, emacs, whatever) with the new name "fixphp.sh", and type in the following:
#!/bin/sh cd the directory that contains the files you want to fix for fixme in *php do sed 's|/www/dadsrights/|/nfs/www/dadsrights.org/|g' $fixme > new mv new $fixme echo fixed $fixme done exit 0That's it. Now, save this out and execute it by feeding it to a subshell:
$ sh fixphp.shYou will want to make sure that you've specified the correct directory in the script as you've typed it in, of course.
Once you run the script, you should see a list of 'fixed xx, fixed yy' and when it completes, all your PHP include_once() directives should be working fine.
