Quick way to write to a file?

jjfletch

I know I can use fopen to open a file and write to it, but I have hundreds of files within a directory and I want to open each one and add the same few lines at the beginning of a file. Is there a way to create a script that will open each file and do this? As far as I can tell, with fopen, you have to specify the filename. Can anyone help?

Look up the directory functions.

You can loop through the files in a directory and apply fopen() to them.

well you can use directory functions with PHP too,

here is a link to file and directory tutorial

i would have to set a loop maybe to open all the files in a folder and all the text.

to get the files names you can use a directory function.

Well, I tried this:

<?php

$dir=opendir("/usr/local/apache/htdocs/D/jtest/");
while($file=readdir($dir)){
if ($file!="." and $file!="..") {
$fp = fopen("$file","r+");
if(!$fp) {
print "error! The file could not be opened";
exit;
}}

$stringtowrite="some text";

fwrite($fp, $stringtowrite);
}
closedir($dir);

But, I get this:

Warning: fwrite(): supplied argument is not a valid stream resource in /usr/local/apache/htdocs/D/txtad.php on line 14

Warning: fopen(1.php): failed to open stream: No such file or directory in /usr/local/apache/htdocs/D/txtad.php on line 6
error! The file could not be opened

Any suggestions?
