frustrated with fgets

darkdirk1

<?php
//prints out the contents of the flat file
function showPage($fileName){
$fp = fopen ("$fileName", "r");
$c=0;
while (!feof ($fp)) {
    $content = fgets( $fp, 5000);

if ($c % 3 == 0){
echo "<tr><td>" . $content . "</td>";
}
elseIf ($c % 3 == 1){
echo "<td>" . $content . "</td>";
}
elseIf ($c % 3 == 2){
echo "<td>" . $content . "</td></tr>";
break;
}

$c++


}
fclose ($fp);}
?>

So there is a bug in this.
I have tried many variations of this function and it keeps failing.

<?php
//prints out the contents of the flat file
function showPage($fileName){
$fp = fopen ("$fileName", "r");
while (!feof ($fp)) {
    $content = fgets( $fp, 5000);
    echo "$content<br>";
}
fclose ($fp);}
?>

this works fine - oh the ways i have tried this.....please advise the likely obvious thing i am screwing up.

thank you much!!!!!

What do you mean by "it keeps failing" ? Is there an error? Does it display incorrectly? Only partial results? Did you view source on the page?

darkdirk1

yea its all blank....Here is the view source produced:

<html>
<head>

i tried a couple other ways out like using file_get_contents() and then exploding it out and running the modulo check on it, still nogo.

bleqh for tonight!!!!

I would guess $fileName does not exist or is empty.
Do a test of $fp to see if the file is being opened.

This code (shown below) works fine and prints the text file contents when called.
All I am changing is this function.
Simply trying to create a 3 column table.

<?php
//prints out the contents of the flat file
function showPage($fileName){
$fp = fopen ("$fileName", "r");
while (!feof ($fp)) {
    $content = fgets( $fp, 5000);
    echo "$content<br>";
}
fclose ($fp);}
?>

Therefore the text file contains valid data - and the function is being properly called.

mtmosier

$c++


}

The lack of a semi-colon should cause a parse error.

darkdirk1

of course!!!!
thats wow.
hum.
i will try and post something tougher next time.

darkdirk1

that definetly was an issue....
but it was still jacked up.
and that let me find a new problem....
So take another look at the function.

<?php
//prints out the contents of the flat file
function showPage($fileName){
$fp = fopen ("$fileName", "r");
$c=0;
echo '<table padding=1 border=1>';
while (!feof ($fp)) {
    $content = fgets( $fp, 5000);

if ($c % 3 == 0){
echo "<tr><td>" . $content . "</td>";
}
elseIf ($c % 3 == 1){
echo "<td>" . $content . "</td>";
}
elseIf ($c % 3 == 2){
echo "<td>" . $content . "</td></tr>";

}

$c++;


}
echo '</table>';
fclose ($fp);}
?>

now my $c %3 == 1 iteration echoes <td></td> but not the content???
All the strings get echoed out but with alternating empty cells in my table......

odd huh?

mtmosier

Is it displaying the first and third line of your text file, and skpping the second? Or is it displaying first and second with an empty cell between?

darkdirk1

ends up looking like this:

and it does unload all the $content - but it doesn't pass the data when ($c % 3 == 1)
evaluates true....

i tried changing the logic around like :

if ($c % 3 == 0){
echo "<tr><td>" . $content . "</td>";
}
elseif ($c % 3 == 2){
echo "<td>" . $content . "</td></tr>";
}
else
{
echo "<td>" . $content . "</td>";
}

same result.

Without seeing your data file that means nothing to me. Probably seeing your data file it would mean nothing, since as far as I can tell all your data is is a bunch of "<a href=''></a>". Think you could put some distinguishing content in your data file then post that along with the output?

darkdirk1

<table padding=1 border=0><tr><td>
<a href='http://www.mylink1'>mylink1</a>
</td><td>
</td><td><a href='http://www.mylink2'>mylink2</a>
</td></tr><tr><td>
</td><td><a href='http://www.mylink3'>mylink3</a>
</td><td>
</td></tr><tr><td><a href='http://www.mylink4'>mylink4</a>
</td><td>
</td><td><a href='http://www.mylink5'>mylink5</a>
</td></tr><tr><td>
</td><td><a href='http://www.mylink6'>mylink6</a>
</td><td>
</td></tr><tr><td><a href=''></a></td></table>

Are you wanting to display each line of the file in a table?
If so use file() and foreach() thru the array.

The code works fine.
I did a little test.

<?
$content = 'hi';
echo "<table>";
for( $c=0;$c<10;$c++ ) {
if ($c % 3 == 0){
echo "<tr><td>" . $content.$c . "</td>";
}
elseIf ($c % 3 == 1){
echo "<td>" . $content.$c . "</td>";
}
elseIf ($c % 3 == 2){
echo "<td>" . $content.$c . "</td></tr>";
}

}
?>

darkdirk1

function showPage($fileName){
$content = file($fileName);
$c=0;
echo '<table name="mainLinko" padding=1 border=0>';
foreach ($content as $link) {
if ($c % 3 == 0){
echo "<tr><td>" . $link . "</td>";
}
elseif ($c % 3 == 2){
echo "<td>" . $link . "</td></tr>";
}
else
{
echo "<td>" . $link . "</td>";
}
$c++;
}
echo '</table>';
}

sorry if i am being dense - but this produces the same blank cell every other spot.

HalfaBee

I just tested your function and it works fine for me.

darkdirk1

okay it's my data source --- i am outputting the darn /n

heheh..

I had tried this code, but i am not understand, the result is craezy....

<?php
$server = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_bind($server, '222.222.222.22'. '4775');
socket_listen($socket);

while (1) {
  $connection = socket_accept($server);

  socket_write($connection, "Hello there\n", strlen("Hello there\n"));
  $input = '';
  while ($connection) {
    $line = socket_read($connection, 4775, PHP_NORMAL_READ);
    //if the client sends QUIT by itself on a line we close the connection.
    if ($line == "QUIT\n") {
       break;
    }
    else {
       //do something with the data, like fget data from socket
    }
  }
  socket_close($connection);
}
socket_close($server);
?>

what meaning of this error on looping time?

cause I just wanna try to get some TCP IP data with any TCP IP listener that created in PHP Code, please tell me how to do it ...?
