php$ Tags = array (Array ('tagid' => 9677, 'tagname' => 'antslice-slogs', 'tagtype' => 2 ,), array ('tagid' => 9678, 'tagname' => 'antelogisy', 'tagtype' => 2); assoc_unique ($ tags, 'tagname ', 'tagtype'); print_r ($ tags); function assoc_unique (& $ arr, $ key, $ key2) {$ res = array (); for ($ I = 0; $ I
  

Combine tagName and tagType as the key of a new array.

The method described above is the easiest! Link the tagName and tagType as the key of the new array, and the duplicate value is automatically filtered out.
