“Php functions are sometimes so confusing”, I don’t know how true that is, but I just found it to be true in this very case. Php’s file_exists, a function that seems like it is made to check if a file exists or not, is the one I encountered recently.
So I created this little test for this very purpose. I created an
images folder with 2 files and 1 folder. Next I used
file_exists function in 3 conditions with respective relative paths, to see which of those existed.
$file1="images/two.jpeg"; $file2="images/icon/one.jpg"; $file3="images/small/icon/"; if (file_exists($file1)) echo "File one exists"; if (file_exists($file2)) echo "File two exists"; if (file_exists($file3)) echo "File three exists";
To my surprise all the conditions returned true.
File one exists File two exists File three exists
file_exists — Checks whether a file or directory exists.According to php.net manual:
Irrespective of existence of file,
file_exists function return true even if the path provided exists, which is in accordance with php manual’s definition, it’s just the name that is confusing. So, its better to use
is_file() together with
file_exists() if the objective is to check if the file really exists or
is_dir()to check for directory.
