PHP の複数画像のアップロード値の問題

INPUTで3つの画像アップロード機能を指定しましたが、画像1は自動的に名前変更できましたが、画像2と3は自動的に変更できませんでした。それ？

$uploaddir = "uploadfiles/";//设置文件保存目录 注意包含/ $type=array("jpg","gif","bmp","jpeg","png");//设置允许上传文件的类型 $patch="uploadfiles/";//程序所在路径 //获取文件后缀名函数 function fileext($filename) { return substr(strrchr($filename, '.'), 1); } //获取文件后缀名函数 function fileext2($filename2) { return substr(strrchr($filename2, '.'), 1); } //获取文件后缀名函数 function fileext3($filename3) { return substr(strrchr($filename3, '.'), 1); } //生成随机文件名函数 function random($length) { $hash = 'java-'; $chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz'; $max = strlen($chars) - 1; mt_srand((double)microtime() * 1000000); for($i = 0; $i < $length; $i++) { $hash .= $chars[mt_rand(0, $max)]; } return $hash; } $a=strtolower(fileext($_FILES['img1']['name'])); $b=strtolower(fileext2($_FILES['img2']['name'])); $c=strtolower(fileext3($_FILES['img3']['name'])); //判断文件类型 if(!in_array(strtolower(fileext($_FILES['img1']['name'])),$type)) { $text=implode(",",$type); echo "您只能上传以下类型文件: ",$text,"<br>"; } //生成目标文件的文件名 else{ $filename=explode(".",$_FILES['img1']['name']); $filename2=explode(".",$_FILES['img2']['name']);$filename3=explode(".",$_FILES['img3']['name']);do { $filename[0]=random(10); //设置随机数长度 $name=implode(".",$filename); //$name1=$name.".Mcncc"; $uploadfile=$uploaddir.$name; $filename[1]=random(10); //设置随机数长度 $name2=implode(".",$filename2); //$name1=$name.".Mcncc"; $uploadfile2=$uploaddir.$name2; $filename[2]=random(10); //设置随机数长度 $name3=implode(".",$filename3); //$name1=$name.".Mcncc"; $uploadfile3=$uploaddir.$name3; } while(file_exists($uploadfile)); if (move_uploaded_file($_FILES['img1']['tmp_name'],$uploadfile)){ //if(is_uploaded_file($_FILES['file']['tmp_name'])){ //输出图片预览 //echo "<center>您的文件已经上传完毕 上传图片预览: </center><br><center><img src='$uploadfile'></center>"; //echo"<br><center><a href='javascript:history.go(-1)'>继续上传</a></center>"; //} //else{ //echo "上传失败！"; } if (move_uploaded_file($_FILES['img2']['tmp_name'],$uploadfile2)){ //if(is_uploaded_file($_FILES['file']['tmp_name'])){ //输出图片预览 //echo "<center>您的文件已经上传完毕 上传图片预览: </center><br><center><img src='$uploadfile'></center>"; //echo"<br><center><a href='javascript:history.go(-1)'>继续上传</a></center>"; //} //else{ //echo "上传失败！"; }if (move_uploaded_file($_FILES['img3']['tmp_name'],$uploadfile3)){ //if(is_uploaded_file($_FILES['file']['tmp_name'])){ //输出图片预览 //echo "<center>您的文件已经上传完毕 上传图片预览: </center><br><center><img src='$uploadfile'></center>"; //echo"<br><center><a href='javascript:history.go(-1)'>继续上传</a></center>"; //} //else{ //echo "上传失败！"; }} $SourceFileName=$uploadfile;$SourceFileName2=$uploadfile2;$SourceFileName3=$uploadfile3;

??はい??、いいえ?? は $filename[0]、$filename[1]、$filename[2] です。 [0],$filename2[0],$filename3[0]

do { $filename[0]=random(10); //设置随机数长度 $name=implode(".",$filename); //$name1=$name.".Mcncc"; $uploadfile=$uploaddir.$name; $filename[1]=random(10); //设置随机数长度 $name2=implode(".",$filename2); //$name1=$name.".Mcncc"; $uploadfile2=$uploaddir.$name2; $filename[2]=random(10); //设置随机数长度 $name3=implode(".",$filename3); //$name1=$name.".Mcncc"; $uploadfile3=$uploaddir.$name3; }

設定が間違っていたようです、ありがとう!
