problem with fseek() and ftell()

[sheraz]

hi sir i m working with fseek() and ftell().

 

i don't know what is the problem.i have just moved the position indicator 4 steps ahead and write the data on file. the code is correctly writing in the file but it is not displaying when i try to display it.

 

here the code is..

 

reading the data from file.

 

 

<?php

if(! $fp=fopen("abc.txt", "w"))

 

die("could not find the required file");

else

{

fseek($fp,4);

fwrite($fp,"welcome to php programming");

}

 

$file=fopen("abc.txt", "r");

$fi=ftell($file);

fseek($file,$fi);

echo fread($file,20);

?>

 

 

it does not display anything. but data has been written on the file.

please help me. :'(

Try closing the file after writing, before reopening it for read only

[ToonMariner]

after writing to the file close it as mark suggests but also clear the status cache (clearstatcache())
