Why is there many php.ini files in a system?

PHP and HTML Problem: Why does Uploading files input not work with some files?

• I created an upload system with php .But the input of files doesn't send any data from SOME files(more than 1MB or 2MB).Why? <form method="post" enctype="multipart/form-data"><input name="userfile" type="file" /></form> (I don't wanna upload the files.I just want to save the NAME of the files into database) By the way, I changed the value of post_max_size and upload_max_filesize to 9999999M and still doesn't working.

• Answer:

  It's the upload_max_filesize that is your problem... Where did you set that value? You can set it in one of two places: Either .htaccess or php.ini. Generally speaking, I've had more success setting it in .htaccess as follows: php_value upload_max_filesize 9M
