Global replace throughout folder

[cmhunt]

Hi

I would like to replace all occurences of one string with another throughout all the files in a folder. There are about 14000 files in this folder averaging about 2kb each. The obvious way I can think of doing this is looping through the directory listing, opening each file, reading each line and replacing contents then writing back.

I can't believe this would be the most efficient way of doing this. Has anyone else got any other ideas?

Not sure if it would have been any quicker but I notice the function file_put_contents() is available in version 5 CVS. I am running version 4.3.2.

Thanks for any help.

Chris

You will probably have to open each individual file and make the substitution using regular expressions.
I would not read each line, read in the entire file and apply the preg_replace() function. Write out the new file after renaming the original (for back out purposes).

Just write a function that opens, reads, replace, renames, writes.

With 14,000 files you might run into a time-out when the script processes longer than the maximum allowed processing time.
