printing newlines in textarea

[Anon]

hi!

This is the whole script I'm currently using :

<?
include("header.inc")
?>

<?
for ($x = 0; $x < strlen($userString); $x++)
{
$thischar = substr($userString, $x, 1);

if ($thischar == " ")
{print (" ");}
else
if ($thischar == "\n")
{print ("\n");}
else
if ($thischar == "a")
{print ("A");}
else

print ("(ERROR)");
}

print ("</textarea>");
print ("<small>MBH</small>");
include("footer.inc")
?>

I have read all articles about this and I've tried everything but it still doesn't work!! can some one help plz!

I want the script to keep the newline as it is but it keeps printing (ERROR) (ERROR) twice!!

Hi again, if you mean the form I'm using here it is :

<FORM ACTION="in.php3" METHOD="post" autocomplete="off">
<CENTER>
<small><b>..:: Original Text ::..</b></small><br>
<textarea rows=10 cols=45 name="userString"></textarea><br><INPUT TYPE="submit" VALUE="In-Code">
</FORM>

Unfortunatily this is the result :

<textarea rows=10 cols=45>
(ERROR)(ERROR)</textarea>
<BR><BR><small><b>..:: Original Text ::..</b></small>
<br><textarea rows=10 cols=45>
</textarea>

You are taking the very very hard route. :-)

I suggest you spend some time just browsing the functions section of the PHP manual. It will give you an idea of what PHP is capable of (as opposed to trying to do a complex task using just the functions you already know)

For your specific problem, use nl2br(), read this:

You don't under stand!

In the beggining of the script I had limited the Chararcters!

for ($x = 0; $x < strlen($userString); $x++)
{
$thischar = substr($userString, $x, 1);

if ($thischar == "a")
{print ("A");}
else

print ("ERROR");
}

So if I put the $thischar as \n the script counts it as two digits not one although it prints a new line but still the error message appears!

I have absolutely no clue what you are trying to do.

What your code does is go through the $userString character by character.

Then when it finds that a character is "a" it prints an "A". But if the character is not "a" it prints "ERROR".

what is the purpose?

well the available digits aint just (a) infact it has all the digits plus ASCII codes

I'm trying some coding thingie so that when a is entered the script changes it to a special code I specify.

yet the script counts the digits that's why it counts \n as one digit so it prints the new line but with the error message.

Here is the whole script code creat a php script witrh this code and try printing a new line ::

<?
include("header.inc")
?>

<?
for ($x = 0; $x < strlen($userString); $x++)
{
$thischar = substr($userString, $x, 1);

if ($thischar == " ")
{print (" ");}
else
if ($thischar == "a")
{print ("tgh.");}
else

print ("(ERROR)");

}

print ("</textarea>\n");
print ("<BR><BR><small><b>..:: Original Text ::..</b></small>\n<br><textarea rows=10 cols=45>$userString</textarea><br>\n<a href=decode.html>( De-Code )</a>");
include("footer.inc")
?>
