Adding multiple values to an associative array in PHP in one call
Solution 1
Try this:
$post_values = array(
"x_login" => "API_LOGIN_ID",
"x_tran_key" => "TRANSACTION_KEY",
);
$array2 = array(
"x_version" => "3.1",
"x_delim_data" => "TRUE",
"x_delim_char" => "|",
"x_relay_response" => "FALSE",
"x_state" => "WA",
"x_zip" => "98004"
);
$result = $post_values + $array2;
Caution however: If the key already exists in $post_values it will not be overwritten.
Solution 2
In order to keep things nice and clean and in this case, simple, you might be better off using array_merge( )
I personally declare any arrays at the top of my class file, in order to make them globally accessible, only because I tend to keep methods free of array declaration (OCD I guess!)
So for me I have an example that might help you, it's something that works for me when needed to add/merge two arrays together:
protected $array1 = array (
'basic' => '1',
'example' => '2',
'for' => '3'
);
protected $array2 = array(
'merging' => '4',
'two' => '5',
'associative' => '6',
'arrays' => '7',
'mate' => '8'
);
Then within your class file, you can use these arrays or any created arrays and merge whenever you want:
public function ExampleOne()
{
$firstArray = $this->array1;
print_r($firstArray);
$secondArray = $this->array2;
print_r($secondArray);
$merged = array_merge($firstArray, $secondArray);
print_r($merged);
}
Each print_r( ) will give you a print out in the console of the data/created array. This is so you can view for yourself that everything has been created correctly and each key has its associated value (check the PHP man pages for a definitive explanation of print_r( ) ).
So, the first array will/should showcase this:
Array
(
[basic] => 1
[example] => 2
[for] => 3
)
The second array will/should showcase this:
Array
(
[merging] => 4
[two] => 5
[associative] => 6
[arrays] => 7
[mate] => 8
)
And the array_merge( ) operation will create the final array, which will/should showcase this:
Array
(
[basic] => 1
[example] => 2
[for] => 3
[merging] => 4
[two] => 5
[associative] => 6
[arrays] => 7
[mate] => 8
)
Of course, you don't always have to place/create your arrays at the top of the class file and when needed you can obviously create arrays within a single function if they are only needed/used within there - what I showcased here was just something I had done recently for a project at work (with the data in these arrays being example data of course!)
Hope this helps people out a bit more :-D
Solution 3
array_push()
will accept an array to be pushed.
But array_merge()
may be more what you want.
Solution 4
You can try using the following function: array_merge

I am trying instantiate an associative array and then in a second call, assign it various other value sets on one block-line. I would like to do this following the same form as in the instantiation:
"variable" = > 'value';
My instantiation is:
$post_values = array( "x_login" => "API_LOGIN_ID", "x_tran_key" => "TRANSACTION_KEY", );
I would like to add:
"x_version" => "3.1", "x_delim_data" => "TRUE", "x_delim_char" => "|", "x_relay_response" => "FALSE", "x_state" => "WA", "x_zip" => "98004"
What are my options? Perhaps there's an array_push usage that I don't know about to add multiple values with more ease? Or am i stuck adding on value per call like:
$post_values['x_version']='3.1'; .... $post_values['x_zip']='98004';
Is there any other graceful way to do add multiple values to an associative array in one line?

ViviDVasT over 12 yearsSeems array_merge overwrites, where + is the same function but does not overwrite. Got it, thanks :)

Baptiste Costa about 9 yearsYou can also use
+=
operator like so$post_values += ['x_version' => '3.1', 'x_zip' => 98004];
