PHP - Question About Fwrite Vs Mysql

Hello,
I'm developing a browser based
chat clients(like the one
facebook and gtalk uses) which
requires an instant generation of
of blocks of html code on clicks.
So, what i'am basically trying to
do is first writes it down the
generated code on a text file
using php fwrite function and
load it immediately into the site
as soon as it is done.
Some disadvantages using this
system of techniques is the
various calculations involved
which i believe will delay in the
deleivery of the code generated.
On the otherhand, this is not so
in the case of mysql database as
all the values are uniquely stored
and determined but the whole
lot process of querying and
reteieving is another factor that i
believe will slow down the
performance.
please tell me which gonna be a
faster one...thanks,

p.s
almost 50percent coding done

So I really don't think I need to paste the code but

Code: [Select]
<?php
session_start();
?>
<?php
$new_thread_page_path = 'general_discussion_threads/' . $_POST['thread_title'] . '.php';
$new_table_link = '<a href="' . $new_thread_page_path . '"' . 'class="hover" border="0" style="text-decoration:none">' . $_POST['thread_title'] . '</a>';
?>
<?php

}
?>


So what all this does is based on user input it creates a new html page based off of the template with a few different variables based on input. Then it makes a new row  and 3 cells in the home pages thread table that link to the page say who made it and what time they made it. Now it all works PERFECT (Im suprised how perfect on the first try actually) except for 1 tiny flaw which i think might be php not me but im not sure. The fwrite creates a new file but if the input contains any question marks (?) the link will work but no file will be created. For everyother character on teh standard keyboard its fine but not the question mark. What gives? thanks yall!

MOD EDIT: <code></code> tags changed to proper [code] . . . [/code] BBCode tags.

I'm putting up a simple text editor for an "about me" website. Here's the basics from the edit page:

<form action="done.php">
   <textarea name="new" style="width: 600px; height: 500px;">
   <? readfile("about.txt"); ?>
   </textarea>
    <input type="submit" value="Save" />
</form>

The old text is put into the form, and once it is re-written, it is sent he

<?
   $_POST["save"] = fopen("about.txt", "w");
   fwrite($_POST["save"], stripslashes($_REQUEST["new"]));
   fclose($_POST["save"]);
?>

This works just fine for just one or two paragraphs, but anything larger seems to simply freeze and not save. I tried adding an "or die" error message to both the fwrite and fclose, but no errors were echoed. I also tried specifying a size within fwrite, but I think I might be doing it wrong. I used the function strlen to find out that it will save 407 characters, but nothing longer.

Thank you for any help or suggestions.

Hi all,

I have fwrite() writing to a text file called 'numbers.txt'. The text file content is "23".

I learn't fwrite() from the manual, so did:

f$fp = fopen('/opt/numbers.txt', 'w');
fwrite($fp, '1');
fclose ($fp);


I have used fwrite() to try and make the file content "123", but fwrite() writes over the content of the file, resulting in it just containing "1".

I couldn't find anywhere about writing into, rather over, and hoping someone could please help me out.

how do i do this please??
i have:
fwrite($fh, $stringDate);

but want to write the next fwrite ($fh,$stringData) on a new line in the text file?

thank you
