You cannot pass PHP arrays to JavaScript directly, so you can convert it to JSON string using json_encode() and use it in JavaScript efficiently. This function is very useful to not only convert PHP array to strings but pass it to javascript as well. These functions even though returns string, have different purpose. Indexed Arrays An indexed or numeric array stores each array element with a numeric index. Multidimensional array An array containing one or more arrays within itself. We will explore two methods to convert array to string in PHP. Associative array An array where each key has its own specific value. Associative arrays are arrays that use named keys that you assign to them. The keys of an indexed array are integers, beginning at 0. Associative arrays are used to store key value pairs. The second is the short syntax that uses. You can create a new array two different ways in PHP. Instead, you can use the employees' names as keys in an associative list, with their salaries as the value. 2 Indexed Versus Associative Arrays There are two kinds of arrays in PHP: indexed and associative. This section will cover how you can create an index array, associative array, and multidimensional array. A numerically indexed array is not the best option for storing employee salaries in an array. What I want at the end as final output is another associative array that counts the number of occurences of the same song by matching 'Title', 'a' and 'b' fields (all three combined defines a unique value). Not just simple indexed arrays, examples to print associative arrays, and multi-dimensional arrays are also included in this guide. There are other ways to convert PHP arrays to string as well. The index of an associative array is a string that allows you to create a strong link between key and value. 1- using for loop 2- using foreach loop 3- use echo statement 4- using printr () function 5- using vardump () function 6- using varexport () function Also, you will learn each method with an example. Convert PHP Array to String using json_encode() and serialize() To create an array in PHP, we use the following syntax: arrayname array(value1,value2.) Here’s an example of creating a simple indexed array containing three elements (numbers). If it is then loop through that array as well. Associative arrays have strings as keys and behave more like two-column tables. The problem with the one before is that there was no way to handle, so this function solves that issue.$users =, 'admins' => ] // function to convert array of arrays to string function implodeArrayofArrays ( $array, $glue = ', ' ) echo implodeArrayofArrays ( $users ) // if your arrays has more levels - multidimensional array then you will have to check whether the item is of Array type or not. Indexed arrays are used when you identify things by their position.

The following function (similar to one above) will render an array as a series of HTML select options (i.e. In PHP, the array () function is used to create an array: array () In PHP, there are three types of arrays: Indexed arrays - Arrays with a numeric index. An associative array is a type of array in PHP that uses named keys instead of numeric keys to access and store values.
