This is another way to get value from a multidimensional array, but for versions of php >= 5.3.

Values in the multi-dimensional array are accessed using multiple index. And each element in the sub-array can be an array, and so on. "" Ī multi-dimensional array each element in the main array can also be an array. NOTE − Don't keep associative array inside double quote while printing otherwise it would not return any value. Instead, we could use the employees names as the keys in our associative array, and the value would be their respective salary. To store the salaries of employees in an array, a numerically indexed array would not be the best choice. Associative array will have their index as string so that you can establish a strong association between key and values.
The associative arrays are very similar to numeric arrays in term of functionality but they are different in terms of their index. This function is explained in function reference. Here we have used array() function to create array.
Php associative array get all values how to#
Exampleįollowing is the example showing how to create and access numeric arrays. These arrays can store numbers, strings and any object but their index will be represented by numbers. NOTE − Built-in array functions is given in function reference PHP Array Functions Numeric Array Multidimensional array − An array containing one or more arrays and values are accessed using multiple indices This stores element values in association with key values rather than in a strict linear index order. Values are stored and accessed in linear fashion.Īssociative array − An array with strings as index. Numeric array − An array with a numeric index. There are three different kind of arrays and each array value is accessed using an ID c which is called array index. There are three different kind of arrays and each array value is accessed using an ID c which is called array. For example if you want to store 100 numbers then instead of defining 100 variables its easy to define an array of 100 length. For example if you want to store 100 numbers then instead of defining 100 variables its easy to define an array of 100 length. An array is a data structure that stores one or more similar type of values in a single value.
