[SOLVED] getting file contents

witakr · May 8, 2007

im adding to the script that which is not included on this script so far a requirement for the file to be created before it can be written to...

I can set it to 0 because thats what the error is... the error is saying that it need to be greater than 0, hence the reason i used 1 and then change it to 0 after reading it.

Are you sure? Does not the error say, file size is zero?

Zero is a character and and the zize of it is more than 0 kb, no?

But if 0 does not work, put the word zero so you do not get conflict with score = 1, unless there is no such a score, but good programming would be word zero....so the script is portable....

this is the error:

Warning: fread() [function.fread]: Length parameter must be greater than 0 in /home/witakr/public_html/scorekeeper/processpoints.php on line 37

there is no possible way to score 0 unless you dont play

0 is consider a character of at least 8 bytes if I am not mistaken.

Post the full code what it currently is and point out line 37. That would help out greatly to solve your problem.

there isnt a problem anymore because I required the file be created before it can be written to and durring the file creation the file has "no score" written to it so that whe n fread() reads it there will be a value great enough to avoid the error...

heres my code:

==============================================

index.php

this script will work if you save them with the correct file names and you chmod a folder called "playerfiles" to 777
