after reading from the form say $_post['name']
how to write back to file in same format as
name:pradeep
You need to try this for yourself, using the file functions referenced earlier. Have a go and post some code and the results if you run into trouble.
We are all prepared to help but we won't write the code for you.

1st open the file in read mode
then take each line in a string using a for loop or so
then using explode searching for the : i wll split name:pradeep into 2 and then assign it some 2 variables;
and then print them in the form .
then use $_post method to read from the form and then write them to the file..
do u hve any suggstions on this
ok i am ready to try .but is the way i am going abt is it alright.

You are not bothering us all, this is what forums are for. It's just that the best way to learn is to have a go.

This process sounds okay to me, I think you are heading down the right road with this idea. Also it's good to plan the process out before you write so full marks there.
I look forward to seeing the result. I'm sure you'll get this working as you need it to and that you will understand what you have done and why it works.

Good to see you have written some code.
Try turning on the error hanlding and telling what you see on the page when you run it. This will shed some light on what is happening.
Also when yo say 'there is some error' what do you mean? What are you currently seeing, what do you think is happening.
My old university tutor would have sent me packing if I'd said 'there's some error please help.' You have to define the problem a bit more, especially as we cannot see your system/setup completely but just the code you post (thanks for posting it).
Let us know what comes back from your next set of tests.

First thing that jumps out at me is that you have PHP code not inside PHP tags:
[HTML]<FORM METHOD=post ACTION="test1.p hp">
for($i=0;$i <= $lcount ;$i++){
<input name= <?php $name[$i] ?> type=text > <?php $value[$i] ?>
}
<INPUT TYPE=SUBMIT>
</form>[/HTML]
which should be:
[HTML]<FORM METHOD=post ACTION="test1.p hp">[/HTML]
[PHP]<?
for($i=0;$i <= $lcount ;$i++){
<input name= <?php $name[$i] ?> type=text > <?php $value[$i] ?>
}
?>[/PHP]
[HTML]<INPUT TYPE=SUBMIT>
</form>[/HTML]

Hi,
Try changing this section
[PHP]
<?
for($i=0;$i <= $lcount ;$i++){
<input name= <?php $name[$i] ?> type=text > <?php $value[$i] ?>
}
?>
[/PHP]
To something more like this:
[PHP]
<?php
for ($i=0; $i <= $lcount; $i++)
{
echo '<input type="text" name=' . $name[$i] . 'value=' . $value[$i] . ' />' ;
}
?>
[/PHP]
The first sample has nested php tags, I don't know if this is a problem or not but it sure looks weird. Also the raw HTML inside the php tags is a potential problem.
The second sample removes the need for this and should work just fine, assuming that the two arrays are correct.
So, your final page could look like this (all in php):
[PHP]
<?php
echo '<form name = "testform" method="post" action="test1.p hp">
';
for ($i=0; $i <= $lcount; $i++)
{
echo '<input type="text" name=' . $name[$i] . 'value=' . $value[$i] . ' />' ;
}
echo '<input type="submit" value="Complete "/>';
echo '</form>';
?>
[/PHP]
Have a play with this and let us know what you get.
Cheers
