Formatting a string for my guestbook

Hey I was wondering if someone here that is good at
working with strings would help me create
guestbook.php for me. I have a string $comments that
I want to write to a file but I want to write it to a
file in such a way that each line of text written to
the file is less then 50 characters long. so that the
file wont have a single line 900 characters long.
I'm not very good with stuff like this but if someone
helps me out I'll have something to look back on as
a reference. I would really like to see some cool php
code also. Also I'll post the complete guestbook.php
code to if anyone would like to see it and I'll post
my web page if anyone wants to sign my guest book.

Here is what I would do (a quick and not complete solution because it doesn't write to file, just shows on screen)
Code:
<?PHP

$Settings['Log']="logs/guestbooklog.txt"; // path to log file
$comments="Formatting a string for my guestbook
-------------

//	if ( (file_exists($Settings['Log'])) && (is_writable($Settings['Log'])) ) {
			$fcontents.="\n".'Date:   '. date("M d, Y").' , '.date("G:i").'h'."\n\n<br>";    //  write Date and Hour to line of contents for file
            $chrlen= strlen($comments);   // get the length of $comments string
			echo "Length of comments: ".$chrlen."<br>";
			$i=0;
			$lengthofline=50;
			while ($i <= $chrlen) {
				$fcontents.=substr($comments,$i,$lengthofline)."\n<br>";   // return $lengthofline characters and make new line
				$i=$i+$lengthofline;
			}  // while loop
			$fcontents.="$$$$$$$$$$$$$$$$$\n<br>";
			echo "File contents:\n<br>".$fcontents;
//    }  // if file exists & is_writable
?>
Now to write to a file you have to remove the "<br>" and make a call to fopen and fwrite to write to a file.

The output would be:
Code:
Length of comments: 716
File contents:
Date: Dec 10, 2011 , 11:36h

The 'function' needs more improvements (maybe to search for ' ' spaces and delimit words and more) but it's a working start for you to continue.

good luck

Post the bit of your code inside [code][/code] or [php][/php] tags, and tell us where you're stuck modifying it. We'll help you learn to fix it yourself, please don't just post or ask for the whole thing.

Edit: lithos has give one starting example, or stick to the guestbook code you said you've already been looking at.

You can split the string into an array with explode(' ', $string)

then run in a foreach loop thru the array in which you add the new word/element to the resulting string. If the resulting string length is beyond a given limit you add a newline or <br >/ tag before adding the element.

Then print the resulting string into the log file.

This way you don't cut words as you would if you only take strlen() to create the new lines.

Alright here is the file. Its still not complete because it writes hard returns
as well as word wrapping every 50 characters. There are some include files that will
keep the php file from being tested and you can delete the last include on the
bottem of the file completly if you want to test the program. Below the php
code is the guestbook.html file. and below that is the segment of code I am working
with.

PHP Code:
<?php
if (!isset($_POST["name"]) || !$_POST["name"])
{
    echo "<p style=\"color:red;font-weight:bold;margin-left:95px\">";
    echo "* A name is required</p>";
    include("guestbook.html");
    exit;
} 
else 
{
    $server   = $_SERVER['REMOTE_ADDR'];
    $name     = $_POST["name"];
    $homepage = $_POST["homepage"];
    $email    = $_POST["email"];
    $comments = $_POST["comments"];
       if (!$syslog = fopen("SYSTEM", "a"))
       {
        $subject = "fopen(\"SYSTEM\", \"a\") failure";
        $header  = "SYSTEM LOG FAILURE";
        $message = "FOPEN FAILED TO OPEN SYSTEM: ".date("F j, Y, g: i a");
        echo "<p style=\"color:red;font-weight:bold;margin-left;95px\">";
           echo "An internal system error has occured.</p>";
           mail('eric_justin_allan@cfl.rr.com',$subject,$message,$header);
           include("guestbook.html");
           exit;
    }
    if(!$handle = fopen("GUESTBOOK","a"))
    {
        fputs($syslog, $server." was unable to open GUESTBOOK ".date("F j, Y, g: i a")."\n");
        fclose($syslog);
        echo "<p style=\"color:red;font-weight:bold;margin-left;95px\">";
        echo "Unable to open the guestbook.</p>";
        include("guestbook.html");
        exit;
    }
    if($_POST["name"])    {fputs($handle, $name."\n");    }else{fputs($handle, "\n");}
    if($_POST["homepage"]){fputs($handle, $homepage."\n");}else{fputs($handle, "\n");}
    if($_POST["email"])   {fputs($handle, $email."\n");   }else{fputs($handle, "\n");}
    if ( (file_exists("GUESTBOOK")) && (is_writable("GUESTBOOK")) ) 
    {
            /* Get the length of $comments string */
            $chrlen= strlen($comments);
            $i=0;
            $lengthofline=50;
            while ($i <= $chrlen) 
            {
                $fcontents.=substr($comments,$i,$lengthofline)."\n";
                $i=$i+$lengthofline;
            }//End while loop
            $fcontents.="$$$$$$$$$$$$$$$$$\n";
            fputs($handle, $fcontents);
    }  // End if file exists & is_writable
    fclose($handle);
    include("redirect_to_guestbook.php");
}

Nice code, although there is a php function for this sort of thing:

PHP Code:
string wordwrap ( string $str, [OPTIONS...]) 
http://php.net/manual/en/function.wordwrap.php

I just stumbled across that but it still has the same problem as the above code. It doesn't
word wrap lines right because if there is text that someone pressed return while typing,
the output will include the returns also.

Is there a function to remove everything accept white spaces and text?

Maybe :
PHP Code:
 if ((file_exists("GUESTBOOK")) && (is_writable("GUESTBOOK")) ) 
    {
            $comments   = str_replace("\n", " ", $comments); 
            $fcontents  = wordwrap($comments, 50);
            $fcontents .= "$$$$$$$$$$$$$$$$$\n";
            fputs($handle, $fcontents);
    }  // End if file exists & is_writable

Alright a finished cool php GUESTBOOK
Alright I finally got it to work. I had to add the line,
$comments = str_replace("\r", "", $comments);
just so thzt my file didn't have squares inside the text.
The first file is called guestbook.php
the second is guestbook.html
and the third should be called redirect_to_guestbook.php

My webpage at the moment is o0oo0.net16.net sign my
guestbook if you want. and thanks for all the help.
Also post some cool php code here.


PHP Code:
<?php
if (!isset($_POST["name"]) || !$_POST["name"])
{
    echo "<p style=\"color:red;font-weight:bold;margin-left:95px\">";
    echo "* A name is required</p>";
    include("guestbook.html");
    exit;
} 
else 
{
    $server   = $_SERVER['REMOTE_ADDR'];
    $name     = $_POST["name"];
    $name = ucfirst($name);
    $homepage = $_POST["homepage"];
    $email    = $_POST["email"];
    $comments = $_POST["comments"];
       if (!$syslog = fopen("SYSTEM", "a"))
       {
        $subject = "fopen(\"SYSTEM\", \"a\") failure";
        $header  = "SYSTEM LOG FAILURE";
        $message = "FOPEN FAILED TO OPEN SYSTEM: ".date("F j, Y, g: i a");
        echo "<p style=\"color:red;font-weight:bold;margin-left;95px\">";
           echo "An internal system error has occured.</p>";
           mail('eric_justin_allan@cfl.rr.com',$subject,$message,$header);
           include("guestbook.html");
           exit;
    }
    if(!$handle = fopen("GUESTBOOK","a"))
    {
        fputs($syslog, $server." was unable to open GUESTBOOK ".date("F j, Y, g: i a")."\n");
        fclose($syslog);
        echo "<p style=\"color:red;font-weight:bold;margin-left;95px\">";
        echo "Unable to open the guestbook.</p>";
        include("guestbook.html");
        exit;
    }
    if($_POST["name"])    {fputs($handle, $name."\n");    }else{fputs($handle, "\n");}
    if($_POST["homepage"]){fputs($handle, $homepage."\n");}else{fputs($handle, "\n");}
    if($_POST["email"])   {fputs($handle, $email."\n");   }else{fputs($handle, "\n");}
    $comments   = str_replace("\n", "", $comments);

Nice to see you got it working,
If this is working for you as you wanted, can you mark the thread solved (read in my signature)

Thank you for posting back the solution.
