Hi,
That's about it, I only mentioned print_r() to aid your understanding.
Without that line in, and adjusting the output you get:
[php]
<?php
$file = fopen("/var/lib/penguin/Desktop/welcome.txt","r ")or exit("Unable to open file!");
$x = 0;
for($i = 0 ; $i != feof($file) ; $i++)
{
$data = fgets($file,$x) ;
$str = explode(':', $data);
for($j = 0; $j < count($str); $j++)
{
echo $str[$j] . "<br />";
}
$x=$x+1024;
}
$lcount=$i;
?
[/php]
This should, I beleive, output the contents of the file to screen.
Now, run it and see what you get. This should enable you to see what you still need to do.
Cheers

this is wht is getting printed in the o/p
"; } $x=$x+1024; } $lcount=$i; ?>
"); $i = $i + 1; } ?>
this is the code tht i am using
[PHP] <?php
$file = fopen("/var/lib/penguin/Desktop/welcome.txt","r ")or exit("Unable to open file!");
$x = 0;
for($i = 0 ; $i != feof($file) ; $i++)
{
$data = fgets($file,$x) ;
$str = explode(':', $data);
for($j = 0; $j < count($str); $j++)
{
echo $str[$j] . "<br />";//lets say $str[0] contains "name" and $str[1] contains "pradeep" .but as we come to 2nd line of the file and this for loop the str[0] wll contain "place" and and str[1] wll contain "bangalore" .this wll be a prob in html calling ..
}
$x=$x+1024;
}
$lcount=$i;
?>
[/PHP]
[HTML]<html>
<head>
</head>
<body>
<FORM METHOD=post ACTION="test1.p hp">
<?
print $lcount;
for($i=0;$i <= $lcount ;$i++){
print("<input name=" . $str[$i] ." type=text value=" . $str[$i+1] ." >");
$i = $i + 1;
}
?>
<INPUT TYPE=SUBMIT>
</form>
</body>
</html>
[/HTML]
ok how to call the in the html separetely i.e name and pradeep..
ie the it shld be lke
the html page must be lke this
name:<input type="text" value="pradeep>
place:<input type="text" value="bangalor e>
see line 11

Just a suggestion but you could format the file differently. So that you have || to separate between full items such as the name and place combination and then && to separate between sub entities. This would give you file like
name:pradeep&&l ocation:bangalo re||name:smith& &location:somew here
Without the need for the low level file functions, as you have no line breaks you do:
[php]
<?php
$lcFileContents = file(_FileName_ );
$laContents = explode("||", $lcFileContents ); // element 0 = name:pradeep&&l ocation:bangalo re
$lnArrayLength = count($laConten ts);
for(i=0; i<=$lnArrayLeng th; $i++)
{
$lcMainSet = $laContents[$i];
$laSubArray = explode["&&", $lcMainSet]; //elemnt 0 = name:pradeep
// nest another appropriate loop and youre away
}
?>
[/php]
Hopefully get the idea, the use of nested loops can get messy so be warned and write useful comments in the code to help sign post the process to anyone else who reads it.
Have a play and let me know how you get on.

the idea got rejected from my boss...the file structure is same.
name:pradeep
place:bangalore

First, please don't shout at me. You are not paying me, I am helping you because I am kind that way.
Second, you need to take the code you've got and try different things. It may be that you have to hard code some rules into the php. I know it sounds nasty but it's not that bad.
Please stop panicing and this project, take a break and then play around with what you've got. My mantra is keep trying and keep learning. That's exactly what you need to do.
I've provided you psuedo code and code samples. It's about time you did something for yourself. As you can see my patience is running out.

Apology accepted.
The final echo line doesn't have a semi-colon on the end.
When yo usay it's nt working what exactly are you getting on screen and in the generated source code?
Also turn on the error reporting in php and see what it tells you, this may give you a clue as to what is going on.
All in all it looks like a nice solution.

Hi pradeepjain,
I have tried this with the following file: -
name:micahel
-
location:Newcastle
-
name:Steven
-
location:Liverpool
-
name:Jamie
-
location:Liverpool
-
Using the following php
[php]
<?php
$filehandle = fopen("test.txt ","r");
$line=true;
echo '<form method=post action=action.p hp>';
while($filehand le && $line)
{
$line = fgets($filehand le);
if (!empty($line))
{
$str = explode(':', $line);
echo $str[0] . ': <input type="text" name="'.$str[0].'" value="'.$str[1].'"><br />';
}
}
echo '<input type=submit value= submit>';
echo '</form>'
?>
[/php]
This gives me a page with 6 text boxes and labels on.
The text file is currently in the same directory as the php file but that shouldn't make any difference.
Hopefully you will get this finished in time for Saturday and will have learnt a bit more about PHP.
Please take some time after this project to read some php tutorials. This will give you a better understanding of the basics and help you to get better at it very quickly.
Cheers
