后,下载后就打不开了.出现了你这个问题我估计是
header('Content-Encoding:
none')
header("Content-type:
application/octet-stream")
header("Accept-Ranges:
bytes")
header("Accept-Length:
".filesize($file_dir."/".$file_name))
header(
'Content-Transfer-Encoding:
binary'
)这几个header产生的.
网上有示例的
<?php/*检测并清除BOM*/
if(isset($_GET['dir'])){
$basedir=$_GET['dir']
}else{
$basedir = '.'
}
$auto = 1
checkdir($basedir)
function checkdir($basedir){
if($dh = opendir($basedir)){
while(($file = readdir($dh)) !== false){
if($file != '.' && $file != '..'){
if(!is_dir($basedir."/".$file)){
echo "filename: $basedir/$file ".checkBOM("$basedir/$file")." <br>"
}else{
$dirname = $basedir."/".$file
checkdir($dirname)
}
}
}//end while
closedir($dh)
}//end if($dh
}//end function
function checkBOM($filename){
global $auto
$contents = file_get_contents($filename)
$charset[1] = substr($contents, 0, 1)
$charset[2] = substr($contents, 1, 1)
$charset[3] = substr($contents, 2, 1)
if(ord($charset[1]) == 239 && ord($charset[2]) == 187 && ord($charset[3]) == 191){
if($auto == 1){
$rest = substr($contents, 3)
rewrite ($filename, $rest)
return "<font color=red>BOM found, automatically removed.</font>"
}else{
return ("<font color=red>BOM found.</font>")
}
}
else return ("BOM Not Found.")
}//end function
function rewrite($filename, $data){
$filenum = fopen($filename, "w")
flock($filenum, LOCK_EX)
fwrite($filenum, $data)
fclose($filenum)
}//end function
?>
bom里面字段ID //不变,每个零件给个id是必须的
pid 用户存储相关的id,可以存入相关的id,用“,”分隔开,在查询的时候获取到$row['pid'],然后用expload()根据逗号分隔开,然后数组在循环带入查找这个相关的id,在获取其他的信息。
art_no //不变
art_name //不变
