You have a foreach loop in your PHP script and you're encountering errors. The loop was supposed to operate on an array, but it may have been given a non-array variable. How would you debug this?
- Use the "for" loop to iterate over the variable
- Use the "if" statement to check if the variable is an array
- Use the "while" loop to iterate over the variable
- Use the "is_array()" function to check if the variable is an array
The correct option is: "Use the 'is_array()' function to check if the variable is an array." To debug the issue, you can use the 'is_array()' function to check if the variable is indeed an array before executing the foreach loop. If the variable is not an array, you can handle the error or provide a fallback mechanism. This helps ensure that the foreach loop operates on an array as intended.
