$ Str = file_get_contents ("http://mil.news.sina.com.cn ");
// Military hotspot
$ Reg = '# [military hotspots]. +? Href = (\ S +) # is ';
Preg_match_all ($ reg, $ str, $ m );
Print_r ($ m );
Array

  Reference:
  
 

   
  


    $ Str = file_get_contents ("http://mil.news.sina.com.cn ");
$ Reg = '#(? <= [Military hotspot]). * (. + )(? = Famous column) # isU ';
Preg_match_all ($ reg, $ str, $ m );
Echo"
";
print_r($m); 

?>



I did not try to write it like this. please take a look.
  
 
 
Its connection does not include quotation marks.
$ Reg = '#(? <= [Military hotspot]). * (. + )(? = Famous column) # isU ';
------ Solution --------------------

$ S_html = file_get_contents ("http://mil.news.sina.com.cn ");
$ S_html = iconv ('gbk', 'utf-8', $ s_html );

$ S_gd_reg = '# [military hotspot ](.*)# IUs ';
$ A_gd_match = array ();
Preg_match_all ($ s_gd_reg, $ s_html, $ a_gd_match );
