Array confusion

[Godfrey]

Alright, hopefully my last question for this current project. I've build an array containing other arrays which each hold 5 values. I'm trying to loop through all the arrays in the main array but only pull out one of the values. What I have right now is:

echo "<ol>";
for ($rw = 0; $rw < sizeof($serenwilde); $rw++)
{
    echo "<li><b>The row number $rw</b>";
    echo "<ul>";

    for ($col = 0; $col < 5; $col++)
    {
        if (isset($serenwilde[$rw][$col])) {
		echo "<li>".$serenwilde[$rw][$col]."</li>";
	}
}

    echo "</ul>";
    echo "</li>";
}
echo "</ol>";

 

Which produces:

The row number 0

value0

value1

value2

value3

value4

 

How can I modify my code so I still loop through all the arrays, but only pull out say value0 from each of them?

 

Thanks again.

use foreach instead of for, for an example

Huh... I was for some reason making that way more complex than needed. Thanks much.

Yes tough they say that for is faster than foreach, but code will be longer. Unless you put it in sperate function...

change

 for ($col = 0; $col < 5; $col++)
    {
        if (isset($serenwilde[$rw][$col])) {
		echo "<li>".$serenwilde[$rw][$col]."</li>";
	}
}

to

 
        if (isset($serenwilde[$rw][0])) {
		echo "<li>".$serenwilde[$rw][0l]."</li>";
	}
