[SOLVED] Remove part or varible

[bmdsherman]

I have a variable, $photo, that is equal to 1.jpg, I want to remove the ".jpg" part from the variable so the variable is only "1", does anybody know how I can do that?

[.josh]

$photo = substr($photo,0,-4);

echo $photo;

 

or

 

$photo = explode('.',$photo);

echo $photo[0];

 

or

 

preg_match('~^[^.]+~',$photo,$match);

echo $match[0];
