本文实例讲述了PHP实现数组根据某个字段进行水平合并,横向合并。分享给大家供大家参考,具体如下:
PHP数组水平合并,横向合并,两条数据合并成一行
需求

代码实现
先将a,b数组合并,判断当前日期下是否空,空的话直接赋值,不空的话,将已有素组和当前数组合并
1
2
3

$total = array_merge ( $a , $b ));
$res = array ();
foreach ( $total as $k => $v ) {
if ( empty ( $res [ $v [ 'date' ]]))
$res [ $v [ 'date' ]] = $v ;
else
$res [ $v [ 'date' ]]= array_merge ( $res [ $v [ 'date' ]], $v );
}
