i have a for loop that lists a number of things. i'm trying to get the total number of things listed in the loop but can't make it work.

any ideas, tips or hints?



this is what my loop looks like (which by the way works great, thanks to moronovich/mike)

PHP Code:

for($i=0;$i<count($selsongvalue); $i++) {

    echo '

    <tr height="20">

        <td class="musicsearchlist">'; $strNumber = $i + 1; echo $strNumber; echo '<!-- song -->'.str_replace('+',' ',$selsongvalue[$i]).'</td>

        <td height="20"><!-- chkbox --><input type="checkbox" name="'.$selcheckboxvalue[$i].'" value="songName='.$selcheckboxvalue[$i].'" checked></td>

        <td></td>

        <td></td>

        <td class="musicsearchlist"><!-- album -->'.str_replace('+',' ',$selalbumvalue[$i]).'</td>

        <td></td>

        <td></td>

        <td class="musicsearchlist">'.str_replace('+',' ',$selartistvalue[$i]).'</td>

        <td></td>

    </tr>'

        ;} 

thankful for any help on this!

Maybe I've misunderstood, but couldn't you use the value of $i?

If not, stick a simple counter at the bottom of the loop and use its value:

$mycounter++;

Each time it loops it'll increment $mycounter. Make sure you initiaslize it before you begin counting or you'll be off by 1 every time.

hi, i know i can use $i but i don't know how to do it. i can use $i to number the rows but not get a total number of rows listed. how is that done?

thanks
