How do i push a new key value pair to an array php?
提问by Tallboy
I know there is a lot of documentation around this but this one line of code took me ages to find in a 4000 line file, and I would like to get it right the first try.
我知道有很多关于此的文档，但是这一行代码花了我很长时间才在一个 4000 行的文件中找到，我想在第一次尝试时就做对。
file_put_contents($myFile,serialize(array($email_number,$email_address))) or die("can't open file");
if ($address != "[email protected]") {
$email['headers'] = array('CC' => '[email protected]');
}
}
After this if statement I basically want to add on
在此 if 语句之后，我基本上想添加
'BCC' => '[email protected]'
'BCC' => '[email protected]'
into the $email['headers']array (so it adds it whether the if evaluates to true or not)
到$email['headers']数组中（因此无论 if 的计算结果是否为真，它都会添加它）

You can add them individually like this:
您可以像这样单独添加它们：
$array["key"] = "value";
Collectively, like this:
总的来说，像这样：
$array = array(
"key" => "value",
"key2" => "value2"
);
Or you could merge two or more arrays with array_merge:
或者您可以合并两个或多个数组array_merge：
$array = array( "Foo" => "Bar", "Fiz" => "Buz" );
$new = array_merge( $array, array( "Stack" => "Overflow" ) );
print_r( $new );
Which results in the news key/value pairs being added in with the old:
这导致新闻键/值对与旧的一起添加：
Array ( [Foo] => Bar [Fiz] => Buz [Stack] => Overflow )

You can do this: $email['headers']['BCC'] = "[email protected]"but you need to add it after the if.
您可以这样做：$email['headers']['BCC'] = "[email protected]"但是您需要在 if 之后添加它。

$email['headers'] = array();
if ($address != "[email protected]") {
$email['headers']['CC'] = '[email protected]';
}
$email['headers']['BCC'] = '[email protected]';
