php,数组

后端开发-php教程

hao123源码 html,ubuntu隐藏顶部菜单,tomcat在45秒内,爬虫爬取全网,php port是什么意思,seo密度多少lzw

如图所示是一个二维数组[别纠结,为了方便我将其转为了json], 其中type只有两个值1和2,

现在需要将type=1的元素转到$new数组中,type=2的转到$old数组中。

PC28 H5源码,电脑上贴着ubuntu,桃子里边有爬虫,闪电标志 php,汉川seo优化lzw

除了用循环还有什么方法没?

附上json:

回复内容：

如图所示是一个二维数组[别纠结,为了方便我将其转为了json], 其中type只有两个值1和2,

现在需要将type=1的元素转到$new数组中,type=2的转到$old数组中。

除了用循环还有什么方法没?

附上json:

/* * 好吧。不知道是不是你需要的。还有想说一句，有这个必要吗？ * */$b = array( array( ype => 1, ame => lisi), array( ype => 2, ame => lisi), array( ype => 1, ame => lisi), array( ype => 1, ame => lisi), );$newArray = array();print_r(array_filter($b,filtertype));echo

;print_r(array_filter($b,filtertypetwo));function filtertype($var){ return $var[ ype] ==1;}function filtertypetwo($var){ return $var[ ype] ==2;}

array_column — 返回数组中指定的一列 (注意版本要求。PHP 5 >= 5.5.0)

2135 , first_name => John , last_name => Doe , ), array( id => 3245 , first_name => Sally , last_name => Smith , ), array( id => 5342 , first_name => Jane , last_name => Jones , ), array( id => 5623 , first_name => Peter , last_name => Doe , )); $first_names = array_column ( $records , first_name ); print_r ( $first_names ); ?> 以上例程会输出：Array( [0] => John [1] => Sally [2] => Jane [3] => Peter)

除了不循环，我想不到别的法子，关注一下，等高人回答。

array_map(function($v){ if($v[ ype] == 1){ $GLOBALS[ ew][] = $v; }else if($v[ ype] == 2){ $GLOBALS[old][] = $v; } }, json_decode($json, true));

$arr = [];//给的数组$result = array_map(function($v){ if($v[ ype] == 1) return $v;},$arr);var_dump($result);
