PHP - 在zip存档中编辑文件，并在关闭之前另存为另一个存档名称

I have a Microsoft Word file that I am using as a template. (testingsample.docx) The plan is to use form input values to create a lease agreement. The code I found below works very well for opening up the .docx file and finding and replacing the required strings. The problem is it only works once. The first time it is ran, it overwrites my template. I am trying to find a way to open testingsample.docx, make the required string changes, and save the archive as testingsamplecopy.docx without altering testingsample.docx.

Thanks in advance for any help!

// Create the Object.
$zip = new ZipArchive();

$inputFilename = 'testingsample.docx';

// Open the Microsoft Word .docx file as if it were a zip file... because it is.
if ($zip->open($inputFilename, ZipArchive::CREATE)!==TRUE) {
    echo "Cannot open $inputFilename :( "; die;
}

// Fetch the document.xml file from the word subdirectory in the archive.
$xml = $zip->getFromName('word/document.xml');

// Replace the strings
$xml = str_replace("1111","Tenant Name Here",$xml);
$xml = str_replace("2222","Address Here",$xml);

// Write back to the document and close the object
if ($zip->addFromString('word/document.xml', $xml)) { echo 'File written!'; }
else { echo 'File not written.  Go back and add write permissions to this folder!l'; }

$zip->close();

header("Location: testingsample.docx");

?>

Just copy from the template file to the target file, then open the target file and not the template.

Also, I changed the code at the header line to use the variable of the name of the file and not a static one.

<?php

// Create the Object.
$zip = new ZipArchive();

$templateFilename = 'testingsample.docx';
$inputFilename = 'testingsamplecopy.docx';

if(!copy($templateFilename, $inputFilename)) {
    die("Could not copy '$templateFilename' to '$inputFilename');
}

// Open the Microsoft Word .docx file as if it were a zip file... because it is.
if ($zip->open($inputFilename, ZipArchive::CREATE)!==TRUE) {
    echo "Cannot open $inputFilename :( "; die;
}

// Fetch the document.xml file from the word subdirectory in the archive.
$xml = $zip->getFromName('word/document.xml');

// Replace the strings
$xml = str_replace("1111","Tenant Name Here",$xml);
$xml = str_replace("2222","Address Here",$xml);

// Write back to the document and close the object
if ($zip->addFromString('word/document.xml', $xml)) { echo 'File written!'; }
else { echo 'File not written.  Go back and add write permissions to this folder!l'; }

$zip->close();

// I also chaned this to use your variable instead of a static value.
header("Location: $inputFilename");

?>
