مجموعه کدهای بدرد بخور در php

[djmohammad]

با استفاده از کد زیر میتوانیم هر فایلی را تا تعداد999 تکه splitکنیم. در ضمن این کد قابلیت rejoinفایل های split شده را دارد.

<pre class="brush: php;" style="direction:ltr;">$filename = "http://www.iyinet.com/my-big-file.zip";
  
$targetfolder = '/tmp';
  
$piecesize = 10; // splitted file size in MB
  
$buffer = 1024;
$piece = 1048576*$piecesize;
$current = 0;
$splitnum = 1;
  
if(!file_exists($targetfolder)) {
    if(mkdir($targetfolder)) {
        echo "Created target folder $targetfolder".br();
    }
}
  
if(!$handle = fopen($filename, "rb")) {
    die("Unable to open $filename for read! Make sure you edited filesplit.php correctly!".br());
}
  
$base_filename = basename($filename);
  
$piece_name = $targetfolder.'/'.$base_filename.'.'.str_pad($splitnum, 3, "0", STR_PAD_LEFT);
if(!$fw = fopen($piece_name,"w")) {
    die("Unable to open $piece_name for write. Make sure target folder is writeable.".br());
}
echo "Splitting $base_filename into $piecesize Mb files ".br()."(last piece may be smaller in size)".br();
echo "Writing $piece_name...".br();
while (!feof($handle) and $splitnum < 999) {
    if($current < $piece) {
        if($content = fread($handle, $buffer)) {
            if(fwrite($fw, $content)) {
                $current += $buffer;
            } else {
                die("filesplit.php is unable to write to target folder. Target folder may not have write permission! Try chmod +w target_folder".br());
            }
        }
    } else {
        fclose($fw);
        $current = 0;
        $splitnum++;
        $piece_name = $targetfolder.'/'.$base_filename.'.'.str_pad($splitnum, 3, "0", STR_PAD_LEFT);
