Its jpg. Look... I don't know exactly what your point,
I'm just asking you about the function to resolve the
size of image like the
codes below:
if (file_exists($img_path)){
list($width,$height) = getimagesizes($img_path);
}else{
$width = $ height = $max_size;
}
So is there any other option to replace file_exists();?
Well, if I do remember correctly, then you are uploading
a file. If
that's the case, then rather than using file_exists()
you should be
using is_uploaded_file. Once you've verified that
is_uploaded_file()
returns true, then use move_uploaded_file() to move the
file to
someplace on your filesystem. If that returns true, then
you should not
have to check file_exists again and just be able to use
get getimagesize().
So, a good function for this would probably be:
function getUploadedImageSize($image, $to_path) {
global $max_size;
$width = $height = $max_size;
if (is_uploaded_file($image)) {
if (move_uploaded_file($image, $to_path)) {
list($width,$height) = getimagesize($to_path);
}
}
return array($width, $height);
}
list($width, $height) = getUploadedImageSize($tmp,
'/the/final/path');
BTW, I don't know if you did a copy and paste from your
code or if you
just typed it in really quickly, but you do have a few
syntactical
errors in the code above. First, the image sizing
function is
getimagesize - singular, not plural. Second, in your
assignment
statement, you have a space where there should not be
one:
$width = $ height = $max_size;
^
Just wanted to make sure you knew about that in case it
was copied and
pasted.
thank you for your input, it really helps.
