Variable not working...

Thunderhawk66

I have a problem, I have this code:

$chelp = str_word_count($add, 0); //Get the number of words
$chelp2 = $chelp -1; //Get the last word
$chelp3 = $chelp -2; //Get the second to last word
$cit = str_word_count($add, 1);
$cfull = "" . $cit[$chelp3] . " " . $cit[$chelp2] . "";	//Put the words together

foreach ($twowords as $val)
{

if ($cfull == $val)
{
$area = $val;
}
else
{
}

}

Basically, $twowords is an array, like so:
"Word One"
"Word Two"

So, what this is meant to do, is look for the two last words, and if it equals a $twowords word (like Word One or Word Two), it will set $area to that.

It seems to work, but when I echo outside of the foreach, it equals nothing, even if a word was found.

Can anyone help?

Where did you define $twowords ?
It's not in the code above at least, could you show us how you define it ?

pppppp

just paste ur full code..

Basically I do it through an include before that code, like:

include('wordlist.php');

And in that include, I'll set the variable like:

$twowords = array(

'Word One',
'Word Two'

);

But all I really want to know is why the variable won't echo outside of the foreach...

Like if I did this:

foreach ($twowords as $val)
{

if ($cfull == $val)
{
$area = "one";
}
else
{
}

} 
echo $area;

It won't echo.

That means that you are wrong - a word was not found.

But all I really want to know is why the variable won't echo outside of the foreach...

Because $cfull is not equal to any element in $twowords, hence $area is never initialised. In fact, you should only use $area if you are sure that it has been declared.

Try this test script:

<?php
$twowords = array(
	'Word One',
	'Word Two'
);

$cfull = 'Word One';

$area = 'not found';
foreach ($twowords as $val)
{
	if ($cfull == $val)
	{
		$area = "one";
	}
}
echo $area;
?>

Thanks for that laserlight, I guess I'll have to check into it more.

Edit: Thanks! It's working now.
