[英]Strip bad Windows filename characters
I found this function that tests whether a string is Windows filename and folder friendly: 我发现这个函数测试一个字符串是Windows文件名和文件夹友好:
function is_valid_filename($name) {
$parts=preg_split("/(\/|".preg_quote("\\").")/",$name);
if (preg_match("/[a-z]:/i",$parts[0])) {
unset($parts[0]);
}
foreach ($parts as $part) {
print "part = '$part'<br>";
if (preg_match("/[".preg_quote("^|?*<\":>","/")."\a\b\c\e\x\v\s]/",$part)||preg_match("/^(PRN|CON|AUX|CLOCK$|NUL|COMd|LPTd)$/im",str_replace(".","\n",$part))) {
return false;
}
}
return true;
}
What I'd rather have is a function that strips all the bad stuff from the string. 我宁愿拥有的是一个从字符串中删除所有不良内容的函数。 I tried to basically replace preg_match with preg_replace but no cigar.
我试着基本上用preg_replace替换preg_match但没有雪茄。
