auの3g2, amcファイルをダウンロードさせるスクリプト

ちょこっとメモ。

<?php
$fileName = "test";
$fileExt  = "3g2";//or amc
$filePath = "/home/data/$fileName.$fileExt";
$fileSize = filesize( $filePath );
if( ! isset( $_SERVER['HTTP_RANGE'] ) ){
header( "Content-Disposition: inline; filename=\"$fileName.$fileExt\"" );
header( "Content-Length: $fileSize" );
if( $fileExt == "3g2" ){
header( "Content-Type: audio/3gpp2" );
}
elseif( $fileExt == "amc" ){
header( "Content-Type: application/x-mpeg" );
}
readfile( $filePath );
exit;
}
else{
list( $range1, $range2 ) = explode( "-", substr( $_SERVER['HTTP_RANGE'], 6 ) );
$len = $range2 - $range1 +1;
$fp  = fopen( $filePath, "rb" );
$buf = fread( $fp, ( $range2 +1 ) );
fclose( $fp );
$buf = substr( $buf, $range1 );
header( "HTTP/1.1 206 Partial content" );
header( "Last-Modified: ".date("D, j M Y G:i:s \\G\\M\\T") );
header( "Pragma: no-cache" );
header( "Accept-Ranges: bytes" );
header( "Content-Length: $len" );
header( "Content-Range: bytes ${range1}-${range2}/${size}" );
if( $fileExt == "3g2" ){
header( "Content-Type: audio/3gpp2" );
}
elseif( $fileExt == "amc" ){
header( "Content-Type: application/x-mpeg" );
}
print( $buf );
exit;
}
?>
