A very simple PHP script to write, read and delete 1000 random files

BenchIO.php

<?php
$sum = [];
$sum['all'] = microtime(true);

$fileNames = [];

$start = microtime(true);
for ($i = 0; $i < 1000; $i++) {
    $fileName = uniqid('FileIO', true);
    file_put_contents($fileName, bin2hex(random_bytes(5)));
    $fileNames[] = $fileName;
}
$sum['write'] = (microtime(true) - $start);

$start = microtime(true);
foreach ($fileNames as $fileName) {
    file_get_contents($fileName);
}
$sum['read'] = (microtime(true) - $start);

$start = microtime(true);
foreach ($fileNames as $fileName) {
    unlink($fileName);
}
$sum['delete'] = (microtime(true) - $start);

echo 'WRITE: ' . $sum['write'] . chr(10);
echo 'READ: ' . $sum['read'] . chr(10);
echo 'DELETE: ' . $sum['delete'] . chr(10);

echo 'ALL: ' . (microtime(true) - $sum['all']) . chr(10);
