.....此处省略相同的代码
看上面的代码.想通过preg_match_all获取一个多维数组(含栏目,文章)
想得类似结果如下:
array(
'栏目1'=>array(
array('/article/110001.html','/images/5.jpg','文章标题1'),
array('/article/110021.html','/images/51.jpg','文章标题2'),
),
'栏目2'=>array(
array('/article/130401.html','/images/23.jpg','文章标题3'),
array('/article/114022.html','/images/26.jpg','文章标题4'),
array('/article/123442.html','/images/89.jpg','文章标题5'),
array('/article/12225.html','/images/42.jpg','文章标题6'),
),
)
每个栏目下的文章数不固定.
谢谢了.

Ia tidak boleh dicapai dengan menggunakan preg_match_all sahaja, tetapi tatasusunan sedemikian boleh dipasang semula.
Anda juga boleh menggunakan queryList, anda akan mengetahuinya oleh Baidu.

Adalah disyorkan untuk menggunakan queryList tatasusunan anda tidak boleh dilaksanakan menggunakan ungkapan biasa, tetapi anda boleh menyambung tatasusunan sendiri selepas memadankan ungkapan biasa

Agak menyusahkan, tetapi anda masih boleh mendapatkan hasil yang anda inginkan
