![]() ![]() Let’s see its equivalent associative array. Let’s see a JSON and its equivalent associative array. PHP has json_decode function that is often used in working with JSON or XML API responses. That’s why it is convenient and insightful to fetch database responses into an associative array.Ī similar example could be decoding a JSON response into an associative array. These databases are often seen in such tabular formats. Some of you might have experience with relational databases like mySQL. This structure can be visualized better in a tabular form. The keys are the names and the values are again associative arrays with some information about the employee. Advertisementsįirst, let’s see how to make a multi-dimensional associative array in PHP. Here, we’ll also see why multi-dimensional are favorable for representing a JSON response. In fact, JSON and XML responses from APIs are parsed and decoded to associative arrays in PHP. An associative array can be multi-dimensional. Multi-dimensional arrays are the one that contains nested arrays. So, we will talk about multi-dimensional associative arrays. So far, we’ve seen single-dimensional associative arrays but they could be multi-dimensional as well. They are favorable for storing a JSON/XML response.Keys provide alot of insights about the data.The keys and values could be any valid PHP data type.PHP has many built-in functions for associative arrays.Here are some features of PHP’s associative arrays. One example is the dictionary in Python which is somewhat similar to associative arrays in PHP. In fact, many other programming languages use this type of data structure. An associative array goes the extra mile by keeping key-value pairs. In general, arrays occur quite frequently in coding. This option adds one key and value at a time. The square bracket syntax is another way to make an associate array in PHP. Advertisements Option 2 – Make an associative array in PHP using square bracket syntax There’s another way which creates key-value pairs one at a time, let’s see that. An associative array with employee-age as key-value pairs. ![]() The code example creates an array with employee names as keys and their ages as values. The key and the value can be any valid PHP data type. $array_variable = array(“key”=>”value”.) We can pass more than one key-value pair separated by commas to the array keyword. One way to make an associative array in PHP is to use the array keyword. ![]() Option 1 – Make an associative array in PHP using the array keyword
