PHP preg_替换和分解函数

我有一些像这样的原始数据

\u002522\u00253A\u002522https\u00253A\u00255C\u00252F\u00255C\

Array
(
      [0] => 
      [1] => 
      [2] => https
      [3] => 
      [4] => 
      [5] => 
      [6] => 


)

我的目的是删除\u0022522https\this之间每个字符串的反斜杠“\”和前7位数字。为此，输出将仅为https

如果只有这样的7位数字\u002522\输出将为空

我的最终目的是将每个结果放入一个数组中，该数组针对上述原始数据进行格式化，如下所示

\u002522\u00253A\u002522https\u00253A\u00255C\u00252F\u00255C\

Array
(
      [0] => 
      [1] => 
      [2] => https
      [3] => 
      [4] => 
      [5] => 
      [6] => 


)

我想要这个结果来构建一个URL。我尝试了

preg\u replace

和

explode

功能以获得预期结果，但失败了

$text = '\u002522\u00253A\u002522https\u00253A\u00255C\u00252F\u00255C\\';
$text = preg_replace("#(\\\\[a-z0-9]{7})#is",",",$text);
$text_array = explode(",",trim($text,'\\'));
print_r($text_array);
