As previously noted this program did not work for me. The above people who had success may have been using unix - it would be interesting to know if that was the case.
For Windows users (i'm presuming this is the point of difference) there is a minor change needed. Where ever the forward slash is used it needs to be replaced with a backslash and of course escaped.
So there are two lines of code that need to be modified as shown below:
$zip->addEmptyDir(str_replace($source . '\', '', $file . '\'));
$zip->addFromString(str_replace($source . '\', '', $file), file_get_contents($file));
it worked for me ,i only assigned value to source variable i.e $source="upload"; then did the escaping for windows. thanks sirgentcode from nigeria
It works, but one problem is that it resets the date/time to the moment the backup was made, not when the original file/folder was made. I rely on these rather crude numbers to find out modifications.
Good
It did not work for me
For windows use this code
function zipData($source, $destination) {
if (extension_loaded('zip')) {
if (file_exists($source)) {
$zip = new ZipArchive();
if ($zip->open($destination, ZIPARCHIVE::CREATE)) {
$source = realpath($source);
if (is_dir($source)) {
$iterator = new RecursiveDirectoryIterator($source);
// skip dot files while iterating
$iterator->setFlags(RecursiveDirectoryIterator::SKIP_DOTS);
$files = new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file) {
$file = realpath($file);
if (is_dir($file)) {
$zip->addEmptyDir(str_replace($source . '', '', $file . ''));
} else if (is_file($file)) {
$zip->addFromString(str_replace($source . '', '', $file), file_get_contents($file));
}
}
} else if (is_file($source)) {
$zip->addFromString(basename($source), file_get_contents($source));
}
}
return $zip->close();
}
}
return false;
}
worked for me
Thanks It works. A note for beginners:
You should change this code:
zipData('myfolder', 'backup.zip');
The first line is a folder the is beside backup.php. So "myfolder" and backup.php are in one folder.
when the files are extracted, their permissions is not the same. i'm using php version 5.6.23
I added a check for empty dir, so that downloading the zip file doesn't throw an error
`<?php function zipData($source, $destination) {
//Added check for empty dir, so that downloading the zip file doesn't throw an error
if (extension_loaded('zip') && file_exists($source) && count(glob($source . DS . '*')) !== 0) {
$zip = new \ZipArchive();
if ($zip->open($destination, \ZIPARCHIVE::CREATE)) {
$source = realpath($source);
if (is_dir($source)) {
$iterator = new \RecursiveDirectoryIterator($source);
// skip dot files while iterating
$iterator->setFlags(RecursiveDirectoryIterator::SKIP_DOTS);
$files = new \RecursiveIteratorIterator($iterator, \RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file) {
$file = realpath($file);
if (is_dir($file)) {
$zip->addEmptyDir(str_replace($source . '', '', $file . ''));
} else if (is_file($file)) {
$zip->addFromString(str_replace($source . '', '', $file), file_get_contents($file));
}
}
} else if (is_file($source)) {
$zip->addFromString(basename($source), file_get_contents($source));
}
}
return $zip->close();
}
return false;
}
?>`
My backup folder is within the root directory. How do I exclude the backup folder?
//kjin uploads file backup
function zipData($source, $destination) {
if (extension_loaded('zip')) {
if (file_exists($source)) {
$zip = new ZipArchive();
if ($zip->open($destination, ZIPARCHIVE::CREATE)) {
$source = realpath($source);
echo $source;
if (is_dir($source)) {
$iterator = new RecursiveDirectoryIterator($source);
// skip dot files while iterating
$iterator->setFlags(RecursiveDirectoryIterator::SKIP_DOTS);
$files = new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file) {
$file = realpath($file);
if (is_dir($file)) {
$zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
} else if (is_file($file)) {
$zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
}
}
} else if (is_file($source)) {
$zip->addFromString(basename($source), file_get_contents($source));
}
}
return $zip->close();
}
}
return false;
}
ini_set('max_execution_time', 600);
ini_set('memory_limit','1024M');
zipData($upload_dir['basedir'], content_url().'/backup.zip');
It is not working

Hello, everyone.
How are you?
I am facing allowed memory error about zip file creation of 10gbyte directory with 3gbyte zip file.
so i googled.
There says that i should removing file_get_contents and use addFile function.
But it is now working.
I hope you help me and i get backup any file size by this github
Thanks.
Nice script. But i use addFile instead addFromString in my backup script:
// ...code
if (is_dir($source) === true) {
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file) {
$file = realpath($file);
if (is_dir($file) === true) {
$zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
} else if (is_file($file) === true) {
$zip->addFile($file, str_replace($source . '/', '', $file));
}
}
} else if (is_file($source) === true) {
$zip->addFile($source, basename($source));
}
// ...code
it's working fine thank u
how can i change dir and file name for each loop through data ??????
Hello Everyone,
Thanks for providing such a nice script to create an archive using php.
I have used this code to create backups of my website.
The code is working perfectly fine but I have an issue i.e. when I run this script at very first, it creates an archive - that is good but if I run the script again it creates an archive which overrides the previous one and includes that old archive into new one.
I want to exclude .zip files from compression.
Can you please help me in this matter?
I want to create an archive which should not contain any archive or .zip file into it.
I will be waiting for kind and positive response.
Thanks & Regards,
Mayank
@toddsby Thanks!
I use this both on Linux and Windows:
$source = <absolute pathname to directory/file to be zipped> . DIRECTORY_SEPARATOR;
$fileName = "myfiles.zip";
$destination = <absolute pathname to destination directory> . DIRECTORY_SEPARATOR . $fileName;
function zip_files( $source, $destination )
{
$zip = new ZipArchive();
if($zip->open($destination, ZIPARCHIVE::CREATE) === true) {
$source = realpath($source);
if(is_dir($source)) {
$iterator = new RecursiveDirectoryIterator($source);
$iterator->setFlags(RecursiveDirectoryIterator::SKIP_DOTS);
$files = new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::SELF_FIRST);
foreach($files as $file) {
$file = realpath($file);
if(is_dir($file)) {
$zip->addEmptyDir(str_replace($source . DIRECTORY_SEPARATOR, '', $file . DIRECTORY_SEPARATOR));
}elseif(is_file($file)) {
$zip->addFile($file,str_replace($source . DIRECTORY_SEPARATOR, '', $file));
}
}
}elseif(is_file($source)) {
$zip->addFile($source,basename($source));
}
}
return $zip->close();
}

Just replace few line and this issue will solve, everytime it will create a new zip
$dest=time()."backup.zip";
zipData('screenshots', $dest);
echo 'Finished.';
Hi,
@prashantkumarabhishek
You are right, But make sure to do not keep backups in site root. Keep it in Hosting root.
Thank you.
Maybe include "exclude folder/file" option now ?
Add ignored list (Array) and directory separator compatibility
`function zipData($source, $destination, $ignores = []) {
if (extension_loaded('zip')) {
if (file_exists($source)) {
$zip = new ZipArchive();
if ($zip->open($destination, ZIPARCHIVE::CREATE)) {
if (is_dir($source)) {
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source, RecursiveDirectoryIterator::SKIP_DOTS), \RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file) {
$ignored = false;
foreach ($ignores as $ignore) {
if(strpos($file, $ignore)){
$ignored = true;
break;
}
}
if($ignored){
continue;
}
if (is_dir($file)) {
$zip->addEmptyDir(str_replace($source . DIRECTORY_SEPARATOR, '', $file . DIRECTORY_SEPARATOR));
} else if (is_file($file)) {
echo(str_replace($source . DIRECTORY_SEPARATOR, '', $file . DIRECTORY_SEPARATOR).'<br>');
$zip->addFromString(str_replace($source . DIRECTORY_SEPARATOR, '', $file), file_get_contents($file));
}
}
} else if (is_file($source)) {
$zip->addFromString(basename($source), file_get_contents($source));
}
}
return $zip->close();
}
}
return false;
}`
In the same lane.
What about a backup program which takes files from a dir and all subdirs newer than a specific date and zips it.
I cant get it to work. is this not working with newer PHP versions? 7.2?
is this code can create zip up 10 GB files into backup of any sites ?
It does not appear to be working for me.
Have made the change mentioned above:
function zipData($folder, $zipTo)
to:
function zipData($source, $destination)
Not sure what chmod is.
Any suggestions?
