PHP注意:未定义的偏移量错误[重复]

This is my codes in compresser.php:

<?php

$filename = "isnotconverted_*";
$files = glob($filename);
$filefound = $files[0];

$new_filefound = str_replace( "isnotconverted_", '', $filefound );

$command = 'ffmpeg -i '.$filefound.' -b 64k -vf "movie=watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:0 [out]" '.$new_filefound;
exec( $command );

unlink( $filefound );

When I open compresser.php directly there is no error and everything is OK, but when I use putty and type /usr/local/bin/php /home/dltvbourse/public_html/compresser.php, I get this error:

PHP Notice:  Undefined offset: 0 in /home/dltvbourse/domains/dl.tvbourse.ir/public_html/compresser.php on line 5

What should I do?

    You should run the php file in the correct folder. So do a:

    cd /home/dltvbourse/public_html/
    /usr/local/bin/php compresser.php
    

    (in putty or whatever ssh client you are using).

    The reason this fails is because glob() uses the current directory as offset directory. Since no files of the pattern are probably placed in the initial directory it won't work.

    Furthermore it is perhaps safe to rewrite your program a bit. After all it is always possible that something goes wrong and no such file is placed in the directory. In that case you probably better check the size of the array and throw an error message.
