PHP ERROR ON IMAGETYPE CODE
Again, keep in mind that this code works fine for jpegs when the final block is not there or commented out. Here's the code from the top to the part that gives the error the rest is more tests and some image operations.
my code: codephperrormessage MaxSize 600000 if (isset(.
I want to exit from the script or at least present a specific message in response to this event.Is there a way to test the image during or before the file_get_contents step that precedes the imagecreatefromstring function?Alternatively, is there a way to replace the error message that is generated before the imagecreatefromstring function starts or completes? I have the code for this, but every place I try to add it, it doesnt work. (The extension has no role or even existence at this point.)However, the TIF image resulted in a error warning that threw me out of the application before the test for "false" could be applied.I tried try/catch in every permutation I could think of but the problem seems to be that the system error is terminating the script before the imagecreatefromstring function completes.Although the likelihood is small that an image upload would be mis-labeled, it has already happened once. (The supported formats are JPEG, GIF, PNG, WBMP and GD2.) It offers the following example as a way to deal with that error:$im = imagecreatefromstring($string) if ($im != false) The GIF image was processed because it is a format supported by the imagecreatefromstring function and it created no problems downstream.
PHP ERROR ON IMAGETYPE MANUAL
This is confirmed by the fact that I uploaded both a GIF and a TIF file with jpg extensions and they passed this test.Later in the script, I process the images with the imagecreatefromstring($string) function.The PHP manual says this function will return "false" if the image type is unsupported, the data is not in a recognized format, or the image is corrupt and cannot be loaded. mime type is what you are looking for and might be what you are referring to.getimagesize only refers to images and may have different results if you are trying to widen the allowed mime types. imagetypes (PHP 4 > 4.0. I test for file type and size of an uploaded file with the following:if (!(($_FILES = "image/jpeg") || ($_FILES = "image/pjpeg")) & ($_FILES < 2000000 ))The PHP Manual says that the file type is passed by the browser and not checked by PHP so the type cannot be taken for granted.
