PHP Unzip the package file to the specified directory implementation

$SRC _file as the file path, upload the file back to the compressed package path

Public function Unzip ($src _file, $dest _dir=false, $create _zip_name_dir=true, $overwrite =true) {

$filePath _arr = [];
if ($zip = Zip_open ($src _file)) {
if ($zip) {
$splitter = ($create _zip_name_dir = = = True)? "." : "/";
if ($dest _dir = = = False) {
$dest _dir = substr ($src _file, 0, Strrpos ($src _file, $splitter)). " /";
}

If the Create target decompression directory does not exist
$this->create_dirs ($dest _dir);

Unzip each file
while ($zip _entry = Zip_read ($zip)) {
The file is not in the root directory
$pos _last_slash = Strrpos (Zip_entry_name ($zip _entry), "/");
if ($pos _last_slash!== false) {
Create a directory at the end of the band/
$this->create_dirs ($dest _dir.substr (Zip_entry_name ($zip _entry), 0, $pos _last_slash+1));
}

Open the Package
if (Zip_entry_open ($zip, $zip _entry, "R")) {

File name is saved on disk
$file _name = $dest _dir.zip_entry_name ($zip _entry);

Check if the file needs to be rewritten

if ($overwrite = = = True | | $overwrite = = = False &&!is_file ($file _name)) {
Read the contents of a compressed file
$fstream = Zip_entry_read ($zip _entry, zip_entry_filesize ($zip _entry));

@file_put_contents ($file _name, $fstream);
Set permissions
chmod ($file _name, 0777);
echo "Save:". $file _name. " <br/> ";
}

Close the entrance
Zip_entry_close ($zip _entry);
}
}
To close a compressed package
Zip_close ($zip);
}
}else{
return false;
}
return $filePath _arr; Returns all file paths after compression
}

/**

$directories = Explode ("/", $path);
