How to save extracted zip file with specific filename - php

Question

I have zip files with only one file inside it, but it has new name every time. I need to extract file and save it with specific file name, not extracted one.
$zip = new ZipArchive;
$res = $zip->open($tmp_name);
if ($res === TRUE) {
$path = _PATH."/files/";
$zip->extractTo($path);
$zip->close();
echo 'Unzip!';
}
Abowe code works, but I need to have specific filename. For example anyfile located under zip (eg. pricelist025.xml should be named temp.xml

Answer 1

Rename your specific file before you extract it.
$zip = new ZipArchive;
$res = $zip->open($tmp_name);
if ($res === TRUE) {
$zip->renameName('pricelist025.xml','temp.xml');
$path = _PATH."/files/";
$zip->extractTo($path);
$zip->close();
echo 'Unzip!';
} else {
echo 'failed, code:' . $res;
}
I hope this works.
UPDATE 1
There is two options if you want to change the file names.
1. change the file names before extracting -This way zip files will be modified
2. change the file names after extracting -Zip files will remain as they were before
Changing file names before extracting
We have to define a pattern for filenames. Here, Files will be in this patter : myfile0.xml, myfile1.html, adn so on..
Note: extension will be preserved.
$zip = new ZipArchive;
$res = $zip->open('hello.zip');
$newfilename = 'myfile';
for($i=0;$i<$zip->count();$i++)
{
$extension = pathinfo($zip->getNameIndex($i))['extension'];
$zip->renameName($zip->getNameIndex($i), $newfilename.$i.'.'.$extension);
}
Chaning file names after extracting
File names will in the same pattern as above.
$directory = 'hello/'; //your extracted directory
$newfilename = 'myfile';
foreach (glob($directory."*.*") as $index=>$filename) {
$basename = pathinfo($filename)['basename'];
if(!preg_match('/myfile\d\./', $basename)) {
$extension = pathinfo($filename)['extension'];
rename($filename,$newfilename.$index.'.'.$extension);
}
}
What we are here scanning the all the files from the extracted directory for which doesn't have a filename in the patter myfile[num]. and then we are changing it's name.
UPDATE 2
I just noticed you have updated your question.
As you have just one file and you want to extract it every time with different name. You should rename it every time you extract.
$zip = new ZipArchive;
$newfilename = "myfile".rand(1,999); //you can define any safe pattern here that suites you
if($zip->open('help.zip')===TRUE)
{
$path = '/your/path/to/directory';
$filename = $zip->getNameIndex(0);
if($zip->extractTo($path))
{
echo "Extracted";
}else{
echo "Extraction Failed";
exit();
}
$extension = pathinfo($filename)['extension'];
rename($path."/$filename",$path."/$newfilename".'.'.$extension);
echo "Extracted with different name successfully!";
} else {
echo "Failed";
}
