Frequently, in our coding journey, we face many common scenarios. One of them is to verify whether the PHP array is empty or not in any kind of array created by you or received from an API.
4 Easy Ways to Check if an Array is Empty
The === [ ] syntax
The empty() function
The count() function
The sizeof() function
In this blog post, we'll explain the four most common ways to check if a PHP array is empty.
1. The === [ ] syntax
Use the === [ ] syntax to check if your PHP array is empty. It is a simple and short technique to find an empty array in PHP. This system is easy to use and keep in mind because of its simple syntax and clear logic.
The reason we are using === instead of == is to confirm that the variable we are looking at is actually an empty array and not just an empty string or integer.
If the array is empty, the expression will return true.
$names = [ ];
$isEmpty = $names === [ ]; // true
//And if the array is not empty, the expression will return fall.
$names = [‘Ram’,’Rohan’ ];
$isEmpty = $names === [ ]; // false
2. The empty() Function
The second method for checking the PHP array is empty or not, is to use an empty function. This in-built PHP function returns a boolean value that indicates whether the variable passed to it is null or empty.
Remember that the empty() PHP function does not work to check if any laravel collection is empty.
If the array is empty, the expression will return true.
$names = [ ];
$isEmpty = empty($names); // true
//And if the array is not empty, the expression will return fall.
$names = ['Ram', 'Rohan'];
$isEmpty = empty($names); // false
3. The count() Function
The third way to check whether your PHP array is empty or not is to apply the count function. This function does not reply to values like true or false. If your array is empty, it replies value 0 (Zero)
In the example, you can see that the PHP array is empty and returns a value of 0.
$names = [ ];
$isEmpty = count($names) === 0; // true
//If the array is not empty, the function must return an integer that is greater than 0
$names = ['Ram', 'Rohan'];
$isEmpty = count($names) === 0; // false
4. The sizeof() Function
The fourth function is the sizeof() function for finding empty PHP arrays in your database. We recommend that you not use the sizeof function because some developers found that it gives the impression that it returns the array size in bytes.
If you want to use the sizeof the function, you can do so to find whether or not the array is empty.
If this array is empty, the function returns 0.
$names = [];
$isEmpty = sizeof($names) === 0; // true
//If the array is not empty, the function must return an integer that is greater than 0.
$names = ['Ram', 'Rohan'];
$isEmpty = sizeof($names) === 0; // false
We also make a document for Check If an Array Is Empty in JavaScript.
We hope that, out of these four options, anyone can help you solve your queries. Now, you can find your empty PHP array in different ways.
