如何在php中将元素添加到子数组 [英] How to add an element into subarray in php
本文介绍了如何在php中将元素添加到子数组的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个数组:
$main_arr = [
0=>[
"el 01",
"el 02",
"el 03",
],
1=>[
"el 11",
"el 12",
"el 13",
],
2=>[
"el 21",
"el 22",
"el 23",
],
];
php中是否有函数或单个语句,例如 ninja_array_method($ main_arr, el new)
,将新元素添加到所有子数组中:
Is there a function or single statement in php like ninja_array_method($main_arr, "el new")
that add new element into all sub arrays to be :
$main_arr = [
0=>[
"el 01",
"el 02",
"el 03",
"el new",
],
1=>[
"el 11",
"el 12",
"el 13",
"el new",
],
2=>[
"el 21",
"el 22",
"el 23",
"el new",
],
];
我只想将这些元素 el new添加到所有数组中,而无需在一行中进行任何更改或类似add_el($ main_arr, el new)
I just want to add these element "el new" into all arrays without any change in one single line or just method like add_el($main_arr, "el new")
推荐答案
使用 foreach循环
和参考 &
:
foreach($data as $ind=>&$ar){
$ar[] = 'el new';
}
Demo
参考&
会突变您的子数组。
Reference &
mutates your subarray.
如果需要函数:
function add_el($data,$elem){
foreach($data as $ind=>&$ar){
$ar[] = $elem;
}
return $data;
}
