Warning Watch your square brackets ([ ]) and parentheses carefully here; it’s really easy to get them mixed up and cause a hard-to-find error. But this code is a little longer, while the code without the if is just a little clearer. Every bit of complexity you can save helps, so this is a nice trick to add to your growing PHP toolkit. You can actually check your code in action at this point. Visit create_user.html and find an image file that’s bigger than 2 MB. Look for a photo in iPhoto or something you’ve pulled straight off your camera. Select that image, and then try and submit your form. You should get something like Figure 8-5 back. Figure 8-5 Here’s one of those beautiful situations where a lot of hard work earlier pays off later. Rather than wading through your code or even writing custom PHP, you were able to quickly hand off an error to your handle_error function and get a nice response. Now multiply that by the hundreds (thousands?) of times you’ll use handle_error, and you’ll start to see the value of having that utility function written early on in your PHP life. Note You might have noticed that even though the image was rejected, your browser still uploads the image—regardless of how big the image is, or what your maximum file size is. That’s because it’s only after the image is uploaded that the size comparison is made. Sort of a bummer, but that’s a browser issue, and not something you can fix with PHP. This page is the result of your code finding an error code, and that error code being matched up to an error in $php_errors—in this case, the image was larger than your HTML allowed.
