list $value

[Anon]

Hello all.

I've go the following:

global $countsearch;
while(list($k, $v) = each($word_count))
{
if($k == "$searchword")
{
$GLOBALS[countsearch] + $v = $GLOBALS[countsearch];
}
}

$countsearch doesn't return anything.

so, what i'm thinking is that it thinks that $v is "1", not 1, so it thinks it's not a number. Is there anyway to get around this and change $v to be a number?

btw: $k is a word and $v is how many times that word is used in a different string. When i do an echo $v; I get "1".

thanks for the help

Try:

global $countsearch;
foreach($word_count as $k => $v)
{
if($k == $searchword)
{
$countsearch += $v;
}
}

You don't need to reference $GLOBALS if you use the global $countsearch; line.

You don't need quotes around $searchword in the if statement.

You should also use foreach($word_count as $k => $v) because it executes faster than list/each and you don't have to call reset() on the array either.

thanks, it all works now.
