二维数组判断值相同
$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]);
}
