Find and replace every instance, everywhere... how to?

[lupus6x9]

I'm renaming my site. I didn't think it was necessary to, so I didn't go through and name everything with $variables. I also have a forum, which links everything with http://myOLDdomain.com/... and I need it to be http://myNEWdomain.com/... . Everywhere.

Is there a relatively simple way to write a PHP script so that I can go to a directory, open EVERY SINGLE FILE, and replace EVERY SINGLE INSTANCE of one string with another?

It might be slow and it might hog my bandwidth/server load, but I'm OK with that. It's a one-time run, so efficiency doesn't matter, and neither does clean code, really.

I'll also need to update my database, but that's not relevant, so I'm just asking for this part here. It would be very helpful if someone could help me write this with at least a segment of code here, because I'm extremely new to PHP still.

NOTE: I'm sorry, but unfortunately my host has disabled the glob() function. I don't know if chmod() works, but I suppose I'll need to CHMOD everything to have write permissions. I can do that in FTP though, so no big deal if that doesn't work.

THanks in advance for your help!

well here's a perl script that will do this for you. If you have perl installed on your system it should be pretty easy to run. If not this isn't terribly hard to convert to php provided you know regex's:

###########################

###########################

use strict;
use warnings;
use File::Slurp;

#Global variables
my $dirPath = undef;
my $tab = "\t";
my $newline = "\n";

# Get the directory to trim files in, then change and open to it
print "Please enter the directory you would like to change the name in: \n";
chomp($dirPath = <STDIN>);
unless(-d $dirPath){ die "The directory path '$dirPath' is not a valid directory, $!"; }
chdir($dirPath) or die "Cannot change to $dirPath, $!";
opendir(BIN, $dirPath) or die "Cannot open $dirPath, $!";

# Go through all php files in the directory
while (defined(my $file = readdir(BIN)))
{
	# If file has a php extension
	if($file =~ /.*\.php/)
	{
		my $stringFile = read_file($file);
                # Replace var1 with what you want to replace, and var2 with what you
                # want to replace it with
		$stringFile =~ s/var1/var2/g;
		# Open the file, and replace it with the string we have
		open(FILE, ">", $file) or die("Cannot open $file, $!");
		print FILE $stringFile;
	}
}

Here's a slightly tweaked version of a script I run to make certain changes in all files with a certain file extension. Should be easy enough to adapt. It traverses the entire directory tree.

chdir($argv[1]) or die('No such directory as '.$argv[1]);
$dirs = array(realpath('.'));
$files = array();
while(count($dirs))
{
	chdir(array_shift($dirs));
	foreach(scandir('.') as $file)
	{
		if($file=='.' || $file=='..') continue;
		if(is_dir($file))
		{
			echo realpath($file),"\n";
			$dirs[] = realpath($file);
			continue;
		}
// this checks the file extension - don't want to alter binaries that might just possibly contain the string.
		if(substr($file,-3)!='.php')
		{
			continue;
		}
		$files[] = realpath($file);
	}
}
echo "\n\n\n";
$files = array_unique($files);

$sr = array(
	"http://olddomain/" => "http://newdomain/",
//... etc., etc., which is why it's an array
);
$s = array_keys($sr);
$r = array_values($sr);
foreach($files as $file)
{
	echo $file,"\n";
	file_put_contents($file, str_replace($s, $r, file_get_contents($file)));
}

It's written to be run from the command line, passing the name of the root of the directory tree to search.

EDIT: Sorry, I was posting a message before your post was displayed.

Thank you, I will try this script.
