check if file exists in php

Question

if (!(file_exists(http://mysite.com/images/thumbnail_1286954822.jpg))) {   
$filefound = \'0\';                         
}

why won\'t this work?

Answer 1

file_exists checks whether a file exist in the specified path or not.

Syntax:

file_exists ( string $filename )

Returns TRUE if the file or directory specified by filename exists; FALSE otherwise.

$filename = BASE_DIR."images/a/test.jpg";
if (file_exists($filename)){
    echo "File exist.";
}else{
    echo "File does not exist.";
}

Another alternative method you can use getimagesize(), it will return 0(zero) if file/directory is not available in the specified path.

if (@getimagesize($filename)) {...}
