Question

I have 2 separate arrays being pulled from MYSQL database, and want to combine both arrays on the key, so I can use a php foreach statement.

*I tried doing 1 query with both, but could not figure out how to get my foreach $video[0] to work.*

match_descr = video code

m_date = date

SQL

    $query = "SELECT match_descr FROM  #__bl_match  WHERE match_descr != '' ORDER BY m_date DESC";
    $db->setQuery($query);
    $videomatch = $db->loadResultArray();

     $query = "SELECT m_date FROM  #__bl_match  WHERE match_descr != '' ORDER BY m_date DESC";
    $db->setQuery($query);
    $videomatch2 = $db->loadResultArray();

PHP

$video = $this->videomatch;

for ($i=1;$i<=1;$i++){
echo '<div id="videoFrame" align="left"><iframe name="videoFrame" title="YouTube video     
player" width="560" height="315"    src="http://www.youtube.com/embed/' . $video[0] . '" frameborder="0"     allowfullscreen=""></iframe></div>';
  echo '<br />';

 echo '<br />';
 echo '<div id="videoThumbnails" align="left">'; 
 echo '<table>';
foreach ($video as $value)
 {

  echo '<tr>';
  echo '<td>';
 echo '<a href="http://www.youtube.com/embed/' . $value . '" target="videoFrame"><img height="75px" width="123px" src="http://img.youtube.com/vi/' . $value. '/2.jpg" alt="' .     $value . '" />    </a>';
echo '</td>';
echo '<td>';
echo (THIS IS WHERE I WOULD LIKE TO PUT THIS VIDEOS DATE);
echo '<br />';
echo 'California';
echo '<br />';
echo '1-19-2012';
echo '</td>';
echo '</tr>';

}
echo '</div>';}

You are (usually) better off selecting both rows in the same query:

SELECT match_descr, m_date FROM  #__bl_match  WHERE match_descr != '' ORDER BY m_date DESC

It appears that you are using Joomla. If this is the case, I don’t think you can use loadResultArray() to iterate multiple columns (you can give it an index to get one of the columns, but that’s not helpful in this case). Instead, you can use loadRowList to get an index array of the columns, or loadAssocList to get an associative array of the columns.

They can be used as follows (without all the html for brevity):

loadRowList:

$query = "SELECT match_descr, m_date FROM  #__bl_match  WHERE match_descr != '' ORDER BY m_date DESC";
$db->setQuery($query);
$videomatch = $db->loadRowList();

foreach ($videomatch as $row) {
    echo "{$row[0]} ({$row[1]})\n";
}

loadAssocList:

$query = "SELECT match_descr, m_date FROM  #__bl_match  WHERE match_descr != '' ORDER BY m_date DESC";
$db->setQuery($query);
$videomatch = $db->loadAssocList();

foreach ($videomatch as $row) {
    echo "{$row['match_desc']} ({$row['m_date']})\n";
}
