How to Push Associative Array in PHP
Usually, we give a basic example that how to push associative array in PHP, First, I have pushed a single key and value inside the associative array. After that, given some more examples like it multiple arrays pushing with the using PHP function.
$arr = array( "name" => "Jonny", "Mob" => "12345", "Email" => "jonny123@gmail.com" ); $arr['Address'] = array( "state" => "delhi", "country" => "India", "pincode" => "123854" ); echo ""; print_r($arr);

in_array() in PHP | Array Value Exists, Associative/Multidimensional
The in_array() example here. Basically array function searches any specific value from the array. Here, We provide in_array in PHP as well as added another example for array value exists with the help index array.
Also, share two examples of in_array associative array PHP and multidimensional. So, you can see the code in the below section.
Although, apply this example for index array and created a $arr variable defined array.
Also, inserted some string values then apply if condition to check array value exists or not in the array. As well As mention output condition.
in_array Associative Array PHP
Similarly, In this example, and in array function only searches values that exist then condition true and false.
So you can see below example have applied for associative array and check value exists with the using in_array().
'php','lang2' => 'java','lang3' => 'python'); if ( in_array( 'java', $arr ) ) < echo 'exists'; >else
in_array() Multidimensional
In this example, we applied for multidimensional arrays. Here, in this array, only one concept to searches value from the array.
Firstly, check the value that which array available value have mention array to array path by array values. and then find as this example display code.
'php', 'lang2' => 'java', 'lang3' => array( 'red','green','blue' ) ); if ( in_array( 'green', $arr['lang3'] ) ) < echo 'exists'; >else

is Array PHP function Example - is_array()
Now output:- Not Available
Therefore, you can see this type out if you put this function is_array( $arr ). It means only give only boolean as true and false. Secondly, put this code anywhere with the condition and check that is an array or not. Also, Check this example empty()

How to Check if an Array is Empty in PHP
In many cases, it is useful to know if the array you're working with is empty or not.
This can be to prevent errors, ensure data integrity, or just to know if you should do something or not.
In this post, we'll learn how you can check if an array is empty or not in PHP.
Using Empty()
The best way to check if an array is empty is to use the empty() function.
This function takes in your array and returns a boolean value, true if the array is empty, and false if it is not.
Let's start out with our example array:
Now let's use the empty() function to check if the array is empty:
As expected, the array is empty, so the empty() function returned true .
Using Count()
Another way you can check if an array is empty is to use the count() function.
This function will return to you the number of elements in the array, so if the array is empty, it will return 0 .
Because this returns to you the number of elements in the array, you can use this information for anything else you need in your program.
Using sizeof()
The last way you can check if an array is empty is to use the sizeof() function.
This function will also return to you the number of elements in the array, so if the array is empty, it will return 0 .
Conclusion
In this post, we learned several ways to check if an array is empty in PHP.
You can either use the empty() function, the count() function, or the sizeof() function.
