$array = array(array('pid'=>1,'name'=>a),array('pid'=>2,'name'=>b),array('pid'=>3,'name'=>c),array('pid'=>1,'name'=>a),array('pid'=>4,'name'=>d));
类似这样的二维数组，怎样判断pid和name同时相等的值(如例子里的('pid'=>1,'name'=>a)值一样)
有的话就退出
------解决方案--------------------
- PHP code
$array = array( array('pid'=>1,'name'=>'a'), array('pid'=>2,'name'=>'b'), array('pid'=>3,'name'=>'c'), array('pid'=>1,'name'=>'a'));$tmp=array();foreach($array as $k=>$v){ if(!$tem[$v[pid].'_'.$v[name]]){ $tem[$v[pid].'_'.$v[name]]=$v; print_r($v); }else{ exit; } }
------解决方案--------------------
- PHP code
$array = array( array('pid' => 1, 'name' => 'a'), array('pid' => 2, 'name' => 'b'), array('pid' => 3, 'name' => 'c'), array('pid' => 4, 'name' => 'd'), array('pid' => 5, 'name' => 'e'), array('pid' => 1, 'name' => 'a'), array('pid' => 4, 'name' => 'd'));$idList = array();foreach ($array as $key => $value) { $idList[] = implode(',', $value);}$idList2 = array_diff_assoc($idList, array_unique($idList));foreach ($idList2 as $key => $value) { $akey = array_search($value, $idList); echo '重复数组:'; print_r($array[$akey]);}
