How can one avoid "Illegal string offset" errors in PHP when accessing array entries?

To avoid "Illegal string offset" errors in PHP when accessing array entries, you should first check if the array key exists before trying to access it. This can be done using the isset() function to verify if the key is set in the array. By doing this check, you can prevent the error from occurring when trying to access a non-existent key. 

// Check if the key exists before accessing it
if(isset($array['key'])) {
    // Access the array entry safely
    $value = $array['key'];
} else {
    // Handle the case where the key does not exist
    $value = null;
}
