php check array empty
- October 13, 2021
I see this a lot in the PHP community, and I always have a question. What do you do when you’re trying to check an array’s size? I’m sure there are ways to do it, but I’m still confused.
The answer is to use the empty() function. According to PHP, this function will return false if the array is not empty. This means that you can safely use empty() whenever you need to check arrays size.
Also, I just wanted to say that this is one of those things that can be confusing to newcomers. I personally have never used the empty function and I think it is usually a good idea to use functions instead of if statements for this type of question.
You can use the empty function, but it is usually a good idea to use functions instead of if statements. It is a bit confusing to newcomers to PHP, so this is something I want to be sure not to confuse them with.
You don’t need to empty an array. You can simply check to see if the elements are empty to determine if the array is empty.
PHP will return false if the values in the array are not empty. It is always better to check if the array elements are empty first, then check if there are values in the array.
The reason you should always check if the array elements are empty is because the function will return false even if there are values in the array. The function may return true if the array is empty, and the if statement will still work because it will return true if the array elements are empty.
Another reason to check the array elements if they are empty is because the array will still return false if the array elements are empty. The same thing will happen if the array elements are not empty though, so you can use the if statement instead of using the if statement.
A good test for an empty array is by using an empty-if statement. You will get an empty array if there are no elements in the array. Otherwise, you will get a value of 0 as an answer.
The test for an empty array is an empty-if statement. This will return false if the array elements are empty, and true if the array elements are not empty.
