Check If Array Contains Substring In PHP

If you’re working with PHP arrays, you may need to check if a specific substring exists in the array. The good news is that there are several built-in PHP functions that can help you accomplish this task. In this blog post, we’ll explore some of these functions and show you how to use them to Check If Array Contains Substring In PHP. Whether you’re a beginner or an experienced PHP developer, this post will provide you with the knowledge you need to efficiently search for substrings in PHP arrays.

Here’s an example of a function that Check If Array Contains Substring In PHP:

This function takes two parameters: an array and a substring to search for. It loops through the array using a foreach loop and uses the strpos() function to check if the substring is present in each array element. If the strpos() function returns a value that is not false, then the function returns true indicating that the substring is present in the array. If the function completes the loop without finding the substring, it returns false.

You can call this function like this:

In this example, we define an array of fruits and a substring to search for. We then call the array_contains_substring() function passing in the array and the substring as parameters.

We use an if statement to check the return value of the function and output a message accordingly.
