PHP - bug in time() function when using ZipArchive - php

Question

I'm using ZipArchive's addEmptyDir/addFile methods to add files to a ZIP file in a loop and measure the current time.
Currently, the relevant part from my code looks like this:
$zip = new ZipArchive();
if (!$zip->open($inProgressZipName, ZIPARCHIVE::CREATE)) {
return array(
"result" => "error"
);
}
echo "start time=" . time() . "\n";
foreach ($list as $filePath) {
echo "loop time=" . time() . "\n";
$file = utf8_decode($filePath);
$zip->addFile($file, str_replace($path . '/', '', $file));
}
echo "end time=" . time() . "\n";
$zip->close();
I'm getting a very wrong output:
start time=1666532175
loop time=1666532175
loop time=1666532175
.
.
loop time=1666532175
loop time=1666532175
end time=1666532175
If I change my code to work with exec command instead like this:
$zip = new ZipArchive();
if (!$zip->open($inProgressZipName, ZIPARCHIVE::CREATE)) {
return array(
"result" => "error"
);
}
echo "start time=" . exec("date +%s") . "\n"; // exec() instead of time()
foreach ($list as $filePath) {
echo "loop time=" . exec("date +%s") . "\n"; // exec() instead of time()
$file = utf8_decode($filePath);
$zip->addFile($file, str_replace($path . '/', '', $file));
}
echo "end time=" . exec("date +%s") . "\n"; // exec() instead of time()
$zip->close();
I'm getting a correct input like this:
1666532505
loop time=1666532505
loop time=1666532505
.
.
loop time=1666532506
loop time=1666532506
.
.
loop time=1666532606
end time=1666532606
As you probably know, I can't use exec because this code will exist on a WordPress plugin, so... what is happening here?

I encounter the same problem before.
Please try to use PharData instead
