Instead, we could use the respective subjectâs names as the keys in our associative array, and the value would be their respective marks gained. For example, to store the marks of different subject of a student in an array, a numerically indexed array would not be the best choice. The most likely use case for this function is to insert a new member into a specific position in the array. An associative array allows to store key/value pairs. This could be replicated, but let's be honest it's not really valuable.Īlso note that in the real world, the length parameter is probably useless in an associative array. Note that in the built in array_splice method, the $length and $replacement parameters are optional. Example 1 A simple array 'bar', 'bar' > 'foo', ) // Using the short array syntax array 'foo' > 'bar', 'bar' > 'foo', > The key can either be an int or a string.
