我正在开发我的游戏网站,但为了让Facebook API正常工作,我必须制作一个新的脚本,可以根据游戏的ID获取缩略图。这是这个脚本试图做的,但我得到了这个错误。
Warning: readfile(localhost/thumbs/6c9e40d35e8cf07e.png) [function.readfile]: failed to open stream: No such file or directory in B:\home\home\thumb.php on line 22
我想知道你们中是否有人可以帮助我。
<?php
require_once "functions.php";
if(!isset($_REQUEST['t'])){
die("No ID Defined");
}
$t = $_REQUEST['t'];
$t = intval($t);
connect();
$fetch = fetchdata("select * from `games` where id = $t");
$thumb = $fetch{'thumb'};
$file = "/thumbs/$thumb";
$filename = basename($file);
$file_extension = strtolower(substr(strrchr($filename,"."),1));
switch( $file_extension ) {
case "gif": $ctype="image/gif"; break;
case "png": $ctype="image/png"; break;
case "jpeg":
case "jpg": $ctype="image/jpg"; break;
default:
}
header($ctype);
readfile($_SERVER['HTTP_HOST'].'/thumbs/'.$thumb);
?>

您不需要http
或https
让PHP readfile
正常工作......实际上使用http会使slower
加载这些图片... 。
readfile('/thumbs/'.$thumb); //or
readfile(PATH_TO_LOCAL_DIR. '/thumbs/'.$thumb);
应该可以正常工作。
这是您的脚本版本,共10行
require_once "functions.php";
if (! isset ( $_REQUEST ['t'] )) {
die ( "No ID Defined" );
}
connect ();
$fetch = fetchdata ( sprintf("select * from `games` where id = '%d'",$_REQUEST ['t']) );
if(!is_file("thumbs/" . $fetch ['thumb'] ))
die("Thum Does not exist");
header ( "Content-type: ", image_type_to_mime_type ( exif_imagetype ( $fetch ['thumb'] ) ) );
readfile ( "thumbs/" . $fetch ['thumb'] );
