I had 2 similar questions before, however after more debugging I came to the conclusion the problem was (probably) not within my own code.
In my code I am trying to unzip a gzipped file, for this I wrote a small method;
<?php
namespace App\Helpers;
class Gzip
{
public static function unzip($filePath)
{
$outFilePath = str_replace('.gz', '', $filePath);
// Open our files (in binary mode)
$file = gzopen($filePath, 'rb');
$outFile = fopen($outFilePath, 'wb');
// Keep repeating until the end of the input file
while (!gzeof($file)) {
// Read buffer-size bytes
// Both fwrite and gzread and binary-safe
fwrite($outFile, gzread($file, 4096));
}
// Files are done, close files
fclose($outFile);
gzclose($file);
}
}
This should result in the unzipped file;
Gzip::unzip('path/to/file.csv.gz');
This is where it gets tricky, sometimes it will unzip the file and sometimes it will throw this exception; (keep in mind that this has nothing to do with the StreamHandler itself, this is a pure input/output error problem)
I can refresh the page as many times as I want but nothing will change, if I would try the gunzip command on the command line it will fail with sort off the same error;
- Which file I am unzipping does not matter, it randomly happens to a random file.
Now it also won't matter if I run the gunzip command multiple times, but like I said these exceptions / errors happen randomly so they also randomly "fix" them self.
The application is written in Laravel 8.0, PHP7.4 running on a Homestead environment (Ubuntu 18.04.5 LTS) my base laptop runs on Windows 10.
To me it's super weird that this exception / error happens randomly and also randomly out of nowhere "fixes" itself, so my question is: how does this happen, why does this happen and ultimately how can I fix it.
