<blockquote>
<div>
<pre class="brush:php;toolbar:false"><div>
<p><?php <br />if ($_files['file']['error'] > 0) {<br>    echo '!problem:';<br>    switch ($_files['file']['error']) {<br>        case 1 :<br>            echo '文件大小超过服务器限制';<br>            break;<br>        case 2 :<br>            echo '文件太大！';<br>            break;<br>        case 3 :<br>            echo '文件只加载了一部分！';<br>            break;<br>        case 4 :<br>            echo '文件加载失败！';<br>            break;<br>    }<br><br>    exit;<br>}<br>if ($_files['file']['size'] > 1000000) {<br>    echo '文件过大！';<br>    exit;<br>}<br>if ($_files['file']['type'] != 'image/jpeg' && $_files['file']['type'] != 'image/gif') {<br>    echo '文件不是jpg或者gif图片！';<br>    exit;<br>}<br>$today = date("ymdhis");<br>$filetype = $_files['file']['type'];<br>if ($filetype == 'image/jpeg') {<br>    $type = '.jpg';<br>}<br>if ($filetype == 'image/gif') {<br>    $type = '.gif';<br>}<br>$upfile = 'upfile/' . $today . $type;<br>if (is_uploaded_file($_files['file']['tmp_name'])) {<br>    if (!move_uploaded_file($_files['file']['tmp_name'], $upfile)) {<br>        echo '移动文件失败！';<br>        exit;<br>    }<br>} else {<br>    echo 'problem!';<br>    exit;<br>}<br>echo '</p>
<h1 id="success">success!</h1>
<br>';<br>echo '文件大小：' . $_files['file']['size'] . '字节' . '<br>';<br>echo '文件路径：' . $upfile;<br>echo '<hr with="100%">' . '<p>';<br>$dirr = 'upfile/';<br>$dir = opendir($dirr);<br>echo $dirr . '--listing:</p>
<ul>';<br>while ($file = readdir($dir)) {<br>    echo "<li>$file</li>";<br>}<br>echo '</ul>';<br>closedir($dir);<br>?></div>

第二种：

<div><blockquote><div>
<?php <br />if (empty ($_get[submit])) {<br>?><br><form enctype="multipart/form-data" action="<?php%20%24_server%5B'php_self'%5D?>?submit=1" method="post">
<br>send this file: <input name="filename" type="file"><br><input type="submit" value="确定上传"><br>
</form>
<br><?php <br /><br>} else {<br>$path = "uploadfiles/"; //上传路径<br><br>//echo $_files["filename"]["type"];<br><br>if (!file_exists($path)) {<br>//检查是否有该文件夹，如果没有就创建，并给予最高权限<br>mkdir("$path", 0700);<br>} //end if<br>//允许上传的文件格式<br>$tp = array (<br>"image/gif",<br>"image/pjpeg",<br>"image/png"<br>);<br>//检查上传文件是否在允许上传的类型<br>if (!in_array($_files["filename"]["type"], $tp)) {<br>echo "格式不对";<br>exit;<br>} //end if<br>if ($_files["filename"]["name"]) {<br>$file1 = $_files["filename"]["name"];<br>$file2 = $path . time() . $file1;<br>$flag = 1;<br>} //end if<br>if ($flag)<br>$result = move_uploaded_file($_files["filename"]["tmp_name"], $file2);<br>//特别注意这里传递给move_uploaded_file的第一个参数为上传到服务器上的临时文件<br>if ($result) {<br>//echo "上传成功!".$file2;<br>echo "<script language="网页特效">";<br />echo "alert("上传成功！");";<br />echo " location='add_aaa.php?pname=$file2'";<br />echo "</script>";<br>} //end if<br><br>}<br>?></div></blockquote></div>
