[英]array_push() with key value pair
I have an existing array to which I want to add a value.我有一个想要添加值的现有数组。
I'm trying to achieve that using array_push()
to no avail.我正在尝试使用
array_push()
来实现这一点,但无济于事。
Below is my code:下面是我的代码:
$data = array(
"dog" => "cat"
);
array_push($data['cat'], 'wagon');
What I want to achieve is to add cat as a key to the $data
array with wagon as value so as to access it as in the snippet below:我想要实现的是将cat作为键添加到
$data
数组中,并以wagon作为值,以便像下面的代码片段一样访问它:
echo $data['cat']; // the expected output is: wagon
How can I achieve that?我怎样才能做到这一点?
那么拥有:
$data['cat']='wagon';
如果您需要添加多个 key=>value,请尝试此操作。
$data = array_merge($data, array("cat"=>"wagon","foo"=>"baar"));
$data['cat'] = 'wagon';
这就是将键和值添加到数组所需的全部内容。
You don't need to use array_push() function, you can assign new value with new key directly to the array like..您不需要使用 array_push() 函数,您可以使用新键直接将新值分配给数组,例如..
$array = array("color1"=>"red", "color2"=>"blue");
$array['color3']='green';
print_r($array);
Output:
Array(
[color1] => red
[color2] => blue
[color3] => green
)
For Example:例如:
$data = array('firstKey' => 'firstValue', 'secondKey' => 'secondValue');
For changing key value:更改键值:
$data['firstKey'] = 'changedValue';
//this will change value of firstKey because firstkey is available in array
output:
输出:
Array ( [firstKey] => changedValue [secondKey] => secondValue )
数组( [firstKey] => changedValue [secondKey] => secondValue )
For adding new key value pair:添加新的键值对:
$data['newKey'] = 'newValue';
//this will add new key and value because newKey is not available in array
output:
输出:
Array ( [firstKey] => firstValue [secondKey] => secondValue [newKey] => newValue )
数组 ( [firstKey] => firstValue [secondKey] => secondValue [newKey] => newValue)
Array['key'] = value;数组['key'] = 值;
$data['cat'] = 'wagon';
This is what you need.这就是你所需要的。 No need to use array_push() function for this.
无需为此使用 array_push() 函数。 Some time the problem is very simple and we think in complex way :) .
有时问题很简单,我们以复杂的方式思考:)。
<?php
$data = ['name' => 'Bilal', 'education' => 'CS'];
$data['business'] = 'IT'; //append new value with key in array
print_r($data);
?>
Result结果
Array
(
[name] => Bilal
[education] => CS
[business] => IT
)
Just do that:就这样做:
$data = [
"dog" => "cat"
];
array_push($data, ['cat' => 'wagon']);
*In php 7 and higher, array is creating using [], not () *在 php 7 及更高版本中,数组是使用 [] 创建的,而不是 ()
