Textarea, reading line by line (Simple I know)

[papaface]

Hello,

How can I read a textareas contents line by line?

e.g

A link on each line that needs to be parsed separately.

 

Is this the right way to do it?

<?php

if	($_POST['submit'])
{
$text = explode("<br />",nl2br($_POST['links']));
foreach ($text as $key => $value)
	{
        echo $key . " => " . $value."<br />";
	}
}
else
{?>
<form name="links" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<textarea name="links" rows="20" cols="50"></textarea>   <br />
<input type="submit" name="submit" value="Send">
</form>
<?php
}
?>

A submitted textarea doesn't contain HTML Linebreaks (br) unless it's actually put in there by the user.

 

\n is what you should be looking for.

Did you actually read my code?

nl2br() converts \n to

<br />

.....

That is why he used the function nl2br. Anyway, what you have should work. However, why don't you just to the explode using "\n", it will work as well, just make sure it is around double quotes.

Didn't even see the nl2br.

<?php

if	($_POST['submit'])
{
$text = explode("\n",$_POST['links']);
foreach ($text as $key => $value)
	{
        echo $key . " => " . $value."<br />";
	}
}
else
{?>
<form name="links" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<textarea name="links" rows="20" cols="50"></textarea>   <br />
<input type="submit" name="submit" value="Send">
</form>
<?php
}
?>

So thats the way to do it?

Yes. It produced this output for me when I tested it:

1 => http://www.yahoo.com

Well I know it works, I am asking if it is the actual best way to do what I want. It seems a bit clumsy to me lol.
