Storing object in binary file

Storing object in binary file

*Note: $obj can be any type of data : object, array, ....

1. Storing object in binary file
//convert obj to binary data
$obj =  new Class();
$serialized_data = serialize($obj);
$binary_data = unpack("C*",$serialized_data);

//store binary data in binary file
$file = fopen('binary', 'w+');
$bin_str = '';
foreach ($binary_data as $data) {
   $bin_str .= $data." ";
}
fwrite($file, $bin_str);
fclose($file);


2. Get object back from binary file
//read data from binary file to array
$binary_array = [];
$lines = file('binary');

foreach ($lines as $line) {
   $datas = explode(' ', $line)
   foreach($datas as $data{
      $binary_array[] = $data;
   }
}

$serialized_data = call_user_func_array('pack', array_merge(array('C*'), $binary_array));
$obj = unserialize($serialized_data);
