Fastest way to utilize file_get_contents() in PHP
Hi guys. I'm making some performance tweaks to a custom Array cache system I built a while ago, and have a question. As it is, I use file_exists() to check if the cache file exists, before using file_get_contents() to load it. Which works very well.
But would it be faster to simply attempt the file_get_contents() straight away, and handle an empty response the same way I would handle file_exists() returning false?
I've tried both ways, and even ran some microtime() to try and find the best way. But I get inconclusive results, so here I am
<?php
if(file_exists($file)) {
$data = json_decode(file_get_contents($file), true);
}
?>VS
<?php
$data = @file_get_contents($file);
if(isset($data) && !empty($data)) {
$data = json_decode($data, true);
}
?>Both work very well, but which is the "best" way?
Thanks in advance.
