How can the error message be resolved by modifying the foreach loop in PHP?

The error message is likely occurring because the foreach loop is trying to iterate over a non-array variable. To resolve this, you can first check if the variable is an array using the is_array() function before trying to iterate over it in the foreach loop. 

if(is_array($variable)){
    foreach($variable as $item){
        // code to process each item
    }
} else {
    // handle the case where $variable is not an array
}
