本篇文章给大家分享php上传功能集后缀名判断和随机命名，代码写的简单易懂，感兴趣的朋友快来参考下吧
不废话了，具体请看下文代码示例讲解。
form.php
upload image upload.php
back; }}
check.php
= 36){$n = 36 + ceil(($n-36)/3) * 3;$captcharesult .= substr($captchasource, $n, 3);}else{$captcharesult .= substr($captchasource, $n, 1);} } return $captcharesult;}?>
将三个文件整合成一个：
= 36){$n = 36 + ceil(($n-36)/3) * 3;$captcharesult .= substr($captchasource, $n, 3);}else{$captcharesult .= substr($captchasource, $n, 1);} } return $captcharesult;}$type = array(jpg, gif, bmp, jpeg, png);// 判断上传文件类型$fileext = strtolower(fileext($_files['file']['name']));$uploadfilename = random(8);if(in_array($fileext, $type)){ $filename = explode(., $_files['file']['name']); if(is_uploaded_file($_files['file']['tmp_name'])){// echo $_files['file']['tmp_name'];$flag = move_uploaded_file($_files['file']['tmp_name'], /library/webserver/documents/test/.$uploadfilename...$fileext);if($flag){echo 上传成功！;}else{echo error.;}echo back; }}?>
upload image 以上内容就是给大家讲解的php上传功能集后缀名判断和随机命名(强力推荐)，，希望大家喜欢。
