How to rename a batch of files in a directory? - php

Question

I have a bunch of files in a directory that I would like to rename. I have a complete list of existing file names and in the column next to the old name, I have a new name (desired) filename, like below: (the list is in excel so I can apply some syntax to all the rows very easily)
OLD NAME NEW NAME
-------- --------
aslkdjal.pdf asdlkjkl.pdf
adkjlkjk.pdf asdlkjdj.pdf
I would like to keep the old name and old files in their current directory and not disturb them, but just create a copy of the file, with the new filename instead.
Not sure what language to use and how to go about doing this.

Answer 1

http://php.net/manual/en/function.rename.php
<?php
rename("/tmp/tmp_file.txt", "/home/user/login/docs/my_file.txt");
?>
EDIT: in case of copy -
<?php
$file = 'example.txt';
$newfile = 'example.txt.bak';
if (!copy($file, $newfile)) {
echo "failed to copy $file...\n";
}
?>

Something like this should work:
$source = '/files/folder';
$target = '/files/newFolder';
$newnames= array(
"oldfilename" => "newfilename",
"oldfilename1" => "newfilename1",
);
// Copy all files to a new dir
if (!copy($source, $target)) {
echo "failed to copy $source...\n";
}
// Iterate through this dir, rename all files.
$i = new RecursiveDirectoryIterator($target);
foreach (new RecursiveIteratorIterator($i) as $filename => $file) {
rename($filename, $newnames[$filename]);
// You might need to use $file as first parameter, here. Haven't tested the code.
}
RecursiveDirectoryIterator documentation.

Just try with the following example :
<?php
$source = '../_documents/fees';
$target = '../_documents/aifs';
$newnames= array(
"1276.aif.pdf" => "aif.10001.pdf",
"64.aif.20091127.pdf" => "aif.10002.pdf",
);
function recurse_copy($src,$dst) {
$dir = opendir($src);
#mkdir($dst);
while(false !== ( $file = readdir($dir)) ) {
if (( $file != '.' ) && ( $file != '..' )) {
if ( is_dir($src . '/' . $file) ) {
recurse_copy($src . '/' . $file,$dst . '/' . $file);
}
else {
copy($src . '/' . $file,$dst . '/' . $file);
}
}
}
closedir($dir);
}
// Copy all files to a new dir
recurse_copy($source, $target);
// Iterate through this dir, rename all files.
$i = new RecursiveDirectoryIterator($target);
foreach (new RecursiveIteratorIterator($i) as $filename => $file) {
#rename($filename, $target.'/'.$newnames[''.$i.'']);
}
?>

This is pretty easy to do with a shell script. Start with the file list as you presented in files.txt.
#!/bin/sh
# Set the 'line' delimiter to a newline
IFS="
"
# Go through each line of files.txt and use it to call the copy command
for line in `cat files.txt`; do
cp `echo $line | awk '{print $1;}'` `echo $line | awk '{print $2};'`;
done
