check for jpg and gif without Zend?

[Geoff]

Hi

Previously I was able to check for an uploaded file to be a jpg or a
gif by using the exif_imagetype() function.

I had to change from hosting provider and the new one doesn't want to
enable Zend on their php.

I would like to have a way to check for a file to be a jpg or gif file
in another way.

Is there anyone who can help me?

Best regards,

Geoff

<?php

$logo="demo/whatever.jpg";

$logosize=getimagesize($logo);

print $logosize[2];

?>
$logosize[2];

If it prints a 2 then its a .jpg file - cant remember what 0 , 1 , 3 ,
etc stand for .
[0] is the width
[1] is the height
[2] is the image type
[3] is the width and height
<img src="<?php print $logo; ?>" width="<?php print $logosize[0]; ?>"
height="<?php print $logosize[1]; ?>" border="0" alt="">

As your grabbing the image info anyway - its usually a good idea to use
the width and height stuff as it saves the webpage from jumping all over
the place .

I think so, I ran into the same problem, only in a different direction, I
had not attempted to upload files using PHP until recently.

I was uploading an image file to a filesystem whilst also entering the
details of the upload into a database - these included FileName, FileSize
and FileType - these were taken from $_FILES['upload']['name'],
$_FILES['upload']['size'], $_FILES['upload']['type'] - GIF and JPG were
represented as image/gif and image/jpeg as the types I uploaded, so I used
the following:

$filetype = $_FILES['upload']['type'];

// upload was the name of the upload field in the previous form.

switch($filetype) {
case 'image/jpeg':
$extention = 'jpg';
break;

case 'image/gif':
$extention = 'gif';

//( the reason for the switch is that I had a lot more image formats to
sort through )

Sorry for the slightly longwinded answer - I was going mostly by memory.

Cheers!
