递归的创建目录-PHP源码

windows api中没有提供现成的多层创建目录、删除目录。这里修改了部分代码实现递归创建目录、删除目录。

//删除目录

bool deletedirectory(char* sdirname)
{
cfilefind tempfind;
char stempfilefind[200] ;

sprintf(stempfilefind,"%s\\*.*",sdirname);
bool isfinded = tempfind.findfile(stempfilefind);
while (isfinded)
{
isfinded = tempfind.findnextfile();

if (!tempfind.isdots())
{
char sfoundfilename[200];
strcpy(sfoundfilename,tempfind.getfilename().getbuffer(200));

if (tempfind.isdirectory())
{
char stempdir[200];
sprintf(stempdir,"%s\\%s",sdirname,sfoundfilename);
deletedirectory(stempdir);
}
else
{
char stempfilename[200];
sprintf(stempfilename,"%s\\%s",sdirname,sfoundfilename);
deletefile(stempfilename);
}
}
}
tempfind.close();
if(!removedirectory(sdirname))
{
return false;
}
return true;
}

// 判断目录是否存在
bool folderexists(cstring s)
{
dword attr;
attr = getfileattributes(s);
return (attr != (dword)(-1) ) &&
( attr & file_attribute_directory);
}

// 创建目录

bool createdir(cstring p)
{
int len=p.getlength();
if ( len <2 ) return false;

if(&＃39;\\&＃39;==p[len-1])
{
p=p.left(len-1);
len=p.getlength();
}
if ( len <=0 ) return false;

if (len <=3)
{
if (folderexists(p))return true;
else return false;
}

if (folderexists(p))return true;



cstring parent;
parent=p.left(p.reversefind(&＃39;\\&＃39;) );

if(parent.getlength()<=0)return false;

bool ret=createdir(parent);

if(ret)
{
security_attributes sa;
sa.nlength=sizeof(security_attributes);
sa.lpsecuritydescriptor=null;
sa.binherithandle=0;
ret=(createdirectory(p,&sa)==true);
return ret;
}
else
return false;
}
