PHP realpath_cache_get() function (with example)

Hey folks,

I've had some experience using the realpath_cache_get() function and thought I'd offer my insights. This function is quite handy when you're working with file paths in PHP and want to leverage the realpath cache for more efficient operations.

Let me share a practical example to give you a better understanding. Suppose you're developing a web application that deals with uploading files and you want to store their real paths in a database. Instead of repeatedly resolving the paths with realpath() function, you can take advantage of the realpath cache.

Here's a snippet of how you could approach it:

php
// Enable and configure the realpath cache

realpath_cache_size(1000); // Set the cache size to accommodate your needs

realpath_cache_ttl(600); // Set the time-to-live for cache entries as per your requirements



// Assuming you received an uploaded file from a form

$uploadedFile = $_FILES['file'];



// Store the real path

$realpath = realpath($uploadedFile['tmp_name']);

if ($realpath) {

    $fileInfo = [

        'originalName' => $uploadedFile['name'],

        'realpath' => $realpath,

        // ... other relevant file details

    ];

    

    // Store the $fileInfo in your database

    // ...

}



// Retrieve the realpath cache entries

$cacheEntries = realpath_cache_get();



// Do something with the cache entries

// ...

Hey there,

I've used the realpath_cache_get() function before, so I can definitely help you out. This function is used to retrieve the entries from the realpath cache, which is a cache of resolved paths to ensure efficient file operations.

To illustrate how you can use realpath_cache_get(), let's say you have a PHP script where you're working with multiple files and you want to retrieve the realpath cache entries for those files. You can do something like this:

php
// Enable the realpath cache

realpath_cache_size(10000); // Set the size of the cache, adjust as needed

realpath_cache_ttl(300); // Set the time-to-live for cached entries, adjust as needed



// Perform operations with your files



// Retrieve the realpath cache entries

$cacheEntries = realpath_cache_get();



// Loop through the cache entries and output them

foreach ($cacheEntries as $path => $realpath) {

    echo "Path: " . $path . ", Realpath: " . $realpath . PHP_EOL;

}
