    Question about comments

    in PHP Coding Help

    Posted

    I have one small question about comments.

     

    say you have a code like this

     

    <?php 

$lol = 1;
$rofl = 2;
$lmao = 3;
// Above are my variable's 

echo 'this does not get executed because the apostrophy in the comment acts as the start';

?>

     

    Now if I wrote this code the apostrophe in variable acts as a quote and does not end until it meets another to end it. Why does this do that? I thought that when you start a comment that whole line gets ignored. 

     

    Could this possible be happening because of my text editor( I use textpad )? If so could you recommend a good text editor, thanks.

    Simple expression problem

    in PHP Coding Help

    Ok I decided to brush up on some functions and this one was giving me a hard time. Basically the if condition is printing the statement even though its not what the expression was asking for.

     

    I'm positive I am just missing something small, but I can't figure it out.

<?php

function count_words()
{
$totalwords = str_word_count($_POST['total']);
$amountneeded = $_POST['amount'];
$wordsneeded = $amountneeded - $totalwords;
$extrawords = $totalwords - $amountneeded;

if (isset($_POST['submitted']))
{
	if(str_word_count($_POST['totalwords']) <= $_POST['amountneeded'])
	{
		print "\nYou need $wordsneeded more words";
	}
	else
	{
		print "\nYou wrote an extra $extrawords words";
	}
	if(str_word_count($_POST['totalwords']) == $_POST['amountneeded'])
	{
		print "You hit the jackpot and got just as much words as you needed";
	}
}
}

?>

<form action="wordcount.php" method="post">

<p>Words Needed: <input type="text" name="amount" value="" /></p>
<p>Copy and Paste your words:</p> <textarea name="total" rows="5" cols="30"></textarea>
<input type="submit" name="submit" value="Count My Words" />
<input type="hidden" name="submitted" value="true" />

</form>

<?php

count_words();

?>
