Read from file and replace

[Anon]

Hi,
I want to read a file, say 'template', replace some strings with 'ereg_replace' and then write the COMPLETE file with these changes to an OTHER file. Any hints?

Do an fopen():

http://www.php.net/fopen

then fread():

http://www.php.net/fread

Then fclose():

http://www.php.net/fclose

then do your regular expression replacements, rinse, lather, and repeat (changing fread to fwrite).

oops, didn't mention that i need lots of replacements ... i actually managed to to only ONE replacement, as fwrite takes only ONE string for writing into that file, does it? is there a simple way to do more than one replacement and then write it back to the file?

Yes, all you need to do is work with the same string that you were using.

$fp = fopen("myfile", "r");
$file = fread($fp, filesize("myfile"));
fclose($fp);

// Please, call me chris
$file = str_replace("God", "Chris", $file);

// Replace all w's with u's
$file = str_replace("w", "u", $file);

// Now write it out.
$fp = fopen("myfile2", "w");
fwrite($fp, $file);
fclose($fp);

All done! You can do a replace on the string as many times as you want before you write the file back out.
