Let's say I have an array like this:
[["code1": '528'], ["code2": '292'], ["code1": '108']]
I am looping through the array to check if a specific key exists. If it doesn't then I am adding it to another array:
$arr[$codename] = $code
However, if the key already exists, then I want to append the $code
value to the existing key's values. I'm not sure how to do this part.
I want the new array to look like this:
[["code1": '528', '108'], ["code2", '292']]
My Answer:
In order to append to an array key in most programming languages, you can follow these general steps:
1. Access the array element using the key.
2. Append the new value to the existing value of the array element.
Here is an example in JavaScript:
javascript
// Define an array
let myArray = {
key1: ['value1', 'value2'],
key2: ['value3', 'value4']
};
// Append a new value to the array element with key 'key1'
myArray['key1'].push('value5');
// Print the updated array
console.log(myArray);
In this example, we accessed the array element with key 'key1' using `myArray['key1']` and then used the `push()` method to append a new value 'value5' to the existing array.
