“如何初始化图片”；blob"；键入PHP构造函数

我有一个类，我想初始化存储pictuer类型为“blob”的列，但我不确定如何初始化？看看代码的lat行

  public function __construct( $data=array() ) {
    if ( isset( $data['id'] ) ) $this->id = (int) $data['id'];
    if ( isset( $data['date'] ) ) $this->date= (int) $data['date'];
    if ( isset( $data['topic'] ) ) $this->topic = preg_replace ( "/[^\.\,\-\_\'\"\@\?\!\:\$ a-zA-Z0-9()]/", "", $data['topic'] );
    if ( isset( $data['author'] ) ) $this->author = preg_replace ( "/[^\.\,\-\_\'\"\@\?\!\:\$ a-zA-Z0-9()]/", "", $data['author'] );
    if ( isset( $data['content'] ) ) $this->content = $data['content'];
    if ( isset( $data['picture'] ) ) $this->picture ="Here sholud be the Type" $data['picture'];
  }

在PHP中，二进制数据也存储在字符串中

因此，只需使用

$this->picture=$data['picture']初始化它
换句话说，PHP的字符串实际上只是字节数组。谢谢@ThiefMaster和deceze@Iman25：如果单击此答案左侧的灰色复选标记图标对您有所帮助，请不要忘记接受此答案。
