PHP absolute file - php

Question

How do we return the absolute path of largest file in a particular directory?
I've been fishing around and haven't turned up anything concrete?
I'm thinking it has something to do with glob()?

Answer 1

$sz = 0;
$dir = '/tmp'; // will find largest for `/tmp`
if ($handle = opendir($dir)) { // will iterate through $dir
while (false !== ($entry = readdir($handle))) {
if(($curr = filesize($dir . '/' . $entry)) > $sz) { // found larger!
$sz = $curr;
$name = $entry;
}
}
}
echo $dir . '/' . $name; // largest

Answer 2

$dir = 'DIR_NAME';
$max_filesize = 0;
$path= '';
foreach(new RecursiveIteratorIterator(new RecursiveDirectoryIterator(realpath($dir),FilesystemIterator::SKIP_DOTS)) as $file){
if ($file->getSize() >= $max_filesize){
$max_filesize = $file->getSize();
$path = $file->getRealPath(); // get absolute path
}
}
echo $path;

Answer 3

function getFileSize($directory) {
$files = array();
foreach (glob($directory. '*.*') as $file) {
$files[] = array('path' => $file, 'size' => filesize($file));
}
return $files;
}
function getMaxFile($files) {
$maxSize = 0;
$maxIndex = -1;
for ($i = 0; $i < count($files); $i++) {
if ($files[$i]['size'] > $maxSize) {
$maxSize = max($maxSize, $files[$i]['size']);
$maxIndex = $i;
}
}
return $maxIndex;
}
usage:
$dir = '/some/path';
$files = getFileSize($dir);
echo '<pre>';
print_r($files);
echo '</pre>';
$maxIndex = getMaxFile($files);
var_dump($files[$maxIndex]);
