Whats wrong in this???

Nik

<?php
ob_start();
error_reporting(E_ALL); $i=0;
echo "<body bgproperties='fixed' background='pics/anemos.bmp'>";

$stream = fopen("e:\web\data.txt", "r");

while(fgetc($stream) != EOF)
{
echo "<font face='Com' size='7' color='Yellow'>";
echo fgetc[$stream];
header("Refresh: 2; URL=http://localhost/test.php");
}

ob_end_flush();
?>

Well, since you didn't say what you are experiencing as a problem, off the bat I can see that you may have problems since you are sending a header() after you are already outputting other stuff...

Hey, rrijnders is back!

I don't think already-sent headers is the problem, as output buffering is turned on before the headers are sent, and not turned off until afterwards.
What does have me beat is why identical refresh headers are being sent for every single character in the file. Since each header will simply replace the previous identical header, it's more silly than damaging, though.

More seriously, what is "fgetc[$stream]" supposed to be? Presumably the character that has just be read, in which case it should have been assigned to a variable when it was got:

while(($char=fgetc($string)!==EOF)
{ ..do stuff with $char
}

rrijnders

Yaah, I'm baaaaack! Just completed my total conversion to Mac! But that's a whole other thread. Let's just say Apache+PostgreSQL+PHP = No problems on OS/X!

Back to this thread:

I don't pretend to know what he wants to do with each character or why he wants to output each one inside a yellow font tag. I thought maybe the goal was to output one chacter with each refresh (?) but the script logic won't even accomplish that. We should probably let the thread die unless he/she posts more detailed info...

Nik

Weedpacker is right! rrijnders - I thought maybe the goal was to output one chacter with each refresh - thats corretct i! i want to do texacly by reading from a file!

like this:

h refresh
he refresh
hel refresh
hell refresh
hello refresh
hello w refresh
hello we refresh
hello wee refresh
hello weed refresh
hello weedp refresh
hello weedpa refresh
hello weedpack refresh
hello weedpacke refresh
hello weedpacket refresh
hello weedpacket! refresh

Cab it be done? 🙂)

ednark

here is a very non-optimized version for you enjoyment: anyone else wanna try this?

#HELLO.TXT
hello weedpacket!

#INDEX.PHP
<?php

$file_name = "hello.txt";
$file_size = filesize($file_name);

$file_offset = isset($_GET['file_offset']) ? $_GET['file_offset'] : 0;
$file_offset = min( $file_offset, $file_size );

$file_so_far = isset($_GET['file_so_far']) ? $_GET['file_so_far'] : '';

$file_stream = fopen($file_name, "r");
fseek($file_stream,$file_offset,SEEK_SET);
$file_so_far .= fread($file_stream,1);
fclose($file_stream);

if ( $file_size > $file_offset ) {
    $file_offset++;
    $more_to_come = 'yes';
    $url_file_so_far = htmlentities(urlencode($file_so_far));
    header("Refresh: 1; URL={$PHP_SELF}?file_offset={$file_offset}&file_so_far={$url_file_so_far}");
} else {
    $more_to_come = 'start over';
    header("Refresh: 3; URL={$PHP_SELF}?file_offset=0");
}

print <<<END
<fieldset style="width:300px">
<legend>Info</legend>
file name = {$file_name} <br/>
file size = {$file_size}<br/>
next offset = {$file_offset}<br/>
more to come ? {$more_to_come}<br/>
</fieldset>
<br />
<br />
<font face='Com' size='7'>{$file_so_far}</font>
END;

?>

Ednark thanks a lot man! this u gave me actully worked just fine!
but i waont to do it in a more simple way liek this

<?php
ob_start();
error_reporting(E_ALL); $i=0;
echo "<body bgproperties='fixed' background='pics/anemos.bmp'>";

$stream = fopen("e:\web\data.txt", "r");

while(($x=fgetc($string))!='EOF')
{
echo "<font face='Com' size='7' color='Yellow'>" .$x;
header("Refresh: 1; URL=http://localhost/test.php");
}

ob_end_flush();
?>

The refresh works ok! The problem as u noticed is in the thatthe script start all over the beginning which means that i dosen remember where it left! i think that i must save somewhere where the fgetc last accesed!

i also wnted to ask if thsi can be done with $file_array=file("data.txt");

Can u help with this man?

try storing the whole file into a string in the session,
then the place in the string you are showing in the session,
then print out just the portion you want.

also i found out that phoenic (my browser of choice) does not handle the header('Refresh') kindly, it tends to collect them and duplicate the refreshes, instead of overwriting one refresh. so i dropped down to using acutal <header> tags

<?php
#session_unset();
#session_destroy();
#die;

/// if this is out first time through
/// store all important info in the session, send off initial refresh header
if ( !isset($_SESSION['file_name']) ) {
    $_SESSION['file_name'] = 'hello.txt';
    $_SESSION['file_size'] = filesize($_SESSION['file_name']);
    $_SESSION['file_text'] = implode('',file($_SESSION['file_name']));
    $_SESSION['file_offset'] = 0;
}
/// unncessary but convenient wrist savers
$file_offset =& $_SESSION['file_offset'];
$file_text   =& $_SESSION['file_text'];
$file_size   =& $_SESSION['file_size'];
$file_name   =& $_SESSION['file_name'];

if ( $file_size > $file_offset ) {
    $file_offset = min(++$file_offset,$file_size);
    $header = "<meta http-equiv='refresh' content='1;URL={$PHP_SELF}'>";
} else {
    $file_offset = 0;
    $header = "<meta http-equiv='refresh' content=''>";
}

/// format the slice of the file we want all pretty for html
$file_so_far = nl2br(htmlentities(substr($file_text,0,$file_offset)));

$displayed_portion   = substr($file_text,0,$file_offset);
$undisplayed_portion = substr($file_text,$file_offset);

print <<<END
<html>
<head>{$header}</head>
<body>
<fieldset style="width:300px">
<legend>Script Info</legend>
file name = {$file_name} <br/>
file size = {$file_size}<br/>
next offset = {$file_offset}<br/>
<fieldset style="width:300px">
<legend>File Content</legend>
<pre><span style="background-color: #DDDDDD;">{$displayed_portion}</span>{$undisplayed_portion}</pre>
</fieldset>
</fieldset>
<br />
<br />
<font face='Com' size='7'>{$file_so_far}</font>
</body>
</html>
END;

?>

Nik

man thanks a lot for that u gave me but if u pls correct my code in order to workas you said!

try storing the whole file into a string in the session,
then the place in the string you are showing in the session,
then print out just the portion you want.

pls be more specific...

Thank you very much!

ednark

i can't be more specific than my code

that little explaination i gave was my code

i don't think you need the ob_start() stuff at all... that can go

you need to read up in the php manual abut what sessions are and how then work, and how they can be used

then look over the string functions in the php manual, i was using the substring function...

after that you should be able to read my code, and then figure out how it relates to what you had

Nik

Thanks!
