How to run two php scripts at the same time in browser and fwrite() in the same file

Question

I have to crash the script. I have a class with a method that opens and writes in the file. I have 2 more files that are the same for calling this method.

I have tried for() loop and sleep()

//Method
    public function write($filename, $text, $sleep)
    {
        $filename .= '.txt';
        $fh = fopen($filename, 'w');
        flock($fh, LOCK_EX);
        $write = fwrite($fh, $text);
        if ($sleep != 0) {
            sleep($sleep);
        }
        fclose($fh);
        return $write;
    }


//firstFile.php

$rw = new RW();

$start = microtime(true);

$rw->write('fileeeeeeee', 'FDSABNIFGA', 0);

echo $time = microtime(true) - $start;


//secondFile.php

$rw = new RW();

$start = microtime(true);

    $rw->write('fileeeeeeee', 'HEHEEH', 0);

echo $time = microtime(true) - $start;

I need to run firstFile.php and secondFile.php at exactly the same time in the browser.

What are you trying to achieve, why do you need to run both at the same time? — Mark, Jul 09 '19 at 10:39

The goal is to crash the script. I want to explore php. @MarkOverton — OmegaSkiller, Jul 09 '19 at 11:17

If you want to deliberately crash a script you could just setup an infinite loop.

for($i = 1; $i != 0; $i++) {
    echo $i . '<br />';
}

No, I have to crash it with writing on the same file. – OmegaSkiller Jul 10 '19 at 06:20
