$dData 是二维数组
$dData = array(
array('id' => 0, 'value' => '绿色吊牌'),
array('id' => 1, 'value' => '红色吊牌'),
array('id' => 1, 'value' => '红色吊牌'),
);
二维数组去重
$tmp = array();
$result = array();
foreach($dData as $key => $val){
$tmp[$key] = json_encode($val);
}
unset($val);
$final = array_unique($tmp);
foreach($final as $key => $val){
$result[$key] = json_decode($val, true);
}
结果：
$result= array(
array('id' => 0, 'value' => '绿色吊牌'),
array('id' => 1, 'value' => '红色吊牌'),
);
