Verifying for an array

Writing functions:

isarray(array)

This function finds out if a variable array is the array, if a returns 1, otherwise 0.

The function of checking whether a variable is an array is an integral part of many programs and systems. It allows you to determine whether a variable has an array property and thus provides control and security during code execution.

If the isarray function is passed the variable arr, which is an array, the function returns 1, and if the function is passed the variable str, which is a string, not an array, and the function returns 0.

Thus, the isarray function provides a reliable and convenient way to check for the massiveness of any variable. It can be used in various projects and applications where it is required to ensure proper data processing and management.
