我可以轉換成這個（？系列化PHP）到SQL並重新創建我的表，如果是的話如何？提前謝謝了。

Answer 1

在PHP中創建一個文件：

<?php 
class AppSchema extends CakeSchema { 

public function before($event = array()) { 
    return true; 
} 

public function after($event = array()) { 
}  

$dir = 'files/'; 
$files = [ 
    'table_names' => 'myapp_cake_model_default_mydb_tablenames', 

]; 
foreach ($files as $table => $file){ 
$content = file(realpath($dir.$file)); 
$content = unserialize($content[1]); 
$info = null; 
foreach ($content as $field => $prop){ 
    $info .= "'$field' => array("; 
     foreach ($prop as $key => $value){ 
      $info .= "'$key' => "; 
      if($key == 'null'){ 
       $info .= empty($value)?'false':'true'; 
      }elseif($key == 'default'){ 
       $info .= empty($value)?'null':"'$value'"; 
      }elseif($key == 'unsigned'){ 
       $info .= empty($value)?'false':'true'; 
      }else{ 
       $info .= empty($value)?"''":"'$value'"; 
      } 
      $info .= ", "; 
     } 
    $info .= "),\n"; 
} 
echo "public $".$table." = array(
    ".$info."'indexes' => array(
     'PRIMARY' => array('column' => 'id', 'unique' => 1), 
    ), 
    'tableParameters' => array('charset' => 'utf8', 'collate' => 'utf8_general_ci', 'engine' => 'InnoDB') 
);\n\n"; 
} 
?> 
} 

然後在瀏覽器中運行它，你應該得到一些代碼粘貼在schema.php文件。然後使用Cake控制檯在MySQL數據庫中創建表。
