count function

[Scott Castillo]

The following line prints something:

echo $keywords[0][3];

However, when I then use the count function as follows:

$count = count($keywords[0]);

echo $count;

The printed count is only 1.

I know there are at least 4 items in the array as I proved above.

The array was created with the preg_split function which I don't think matters.

I don't know what I'm doing wrong. Seems simple.

No, you didn't.
You proved that either $keywords[0] is not an array or it has one item.

<?php
$a[0] = 'abcdef';
echo $a[0][3], "\n";
echo count($a), "\n\n";

$b[0][3] = 'something';
echo $b[0][3], "\n";
echo count($b[0]), "\n\n";

$c[0][0] = 'zero';
$c[0][1] = 'one';
$c[0][2] = 'two';
$c[0][3] = 'three';
$c[0][4] = 'four';
echo $c[0][3], "\n";
echo count($c[0]), "\n\n";
?>
