1, pass plan law:
It is quotative content below: DeleteDir(＄ Dir)
{Dir of If (rmdir(＄ )==False &&Is_dir(＄ Dir)) {Dir)) {of ＄ of Dp = Opendir(of If (＄Dp)) of ＄ of File=readdir(of While ((＄ ! = False) {File) & of If (is_dir(＄&＄ File! =’ . ‘ &&＄ File! =’ . . ‘) {DeleteDir(＄ File);
} Else {Unlink(＄ File);
}
}Closedir(＄ Dp);
} Else {Exit(’Not Permission’);
}
}
} |
2, the system calls a way
It is quotative content below: Dir of Function Del_dir(＄ )
{If(strtoupper(substr(PHP_OS, 0, 3) )==’WIN’) {
＄ Str = “rmdir /s/q ” . ＄ Dir;
} Else {
＄ Str = “rm -Rf ” . ＄ Dir;
}
} |
3, circular law
| It is quotative content below:
Pathdir of Function Deltree(＄ )
{When I debug Pathdir;// of Echo ＄ , useIf If(is_empty_dir(＄ Pathdir))// is empty
{Rmdir(＄ Pathdir);// is deleted directly
}Else
{// reads this list otherwise, besides. And. . Outside
＄ D=dir(＄ Pathdir);D->read() of ＄ of While(＄ A= )
{If(is_file(＄ Pathdir. ‘/’ . ＄ A) &&(＄ A! =’ . ‘) &&(＄ A! =’ . . ‘)){unlink(＄ Pathdir. ‘/’ . ＄ A);}
/ / if be a file,delete directlyIf(is_dir(＄ Pathdir. ‘/’ . ＄ A) &&(＄ A! =’ . ‘) &&(＄ A! =’ . . ‘) )

}
}
}
＄ D->close();Echo ” must delete what when I debug all file ” ;// below catalog, use first
}
}Pathdir of Function Is_empty_dir(＄ )
{
