What potential issues can arise from not checking if a variable is an array before using it in PHP?

Potential issues that can arise from not checking if a variable is an array before using it in PHP include errors or unexpected behavior when trying to access array-specific functions or properties on a non-array variable. To solve this, you can use the `is_array()` function to check if a variable is an array before using it in array operations. 

// Check if the variable is an array before using it
if (is_array($myVariable)) {
    // Perform array operations on $myVariable
    foreach ($myVariable as $value) {
        echo $value . "<br>";
    }
} else {
    echo "Variable is not an array";
}
