Convert Array to String PHP
There is always an issue with manipulating arrays in PHP. Although they are widely used and fully supported, PHP faces a few drawbacks when working with arrays.
For example, to echo a single element of an array, you can convert the array to a string and print it on the screen.
In this tutorial, you will learn how to convert a PHP array to a string.
