combinar dos bucles foreach

Question

Tengo dos bucles foreach: primero uno:

 foreach ($items as $key => $item)
{
$keywords = explode('' '', $qsvarus);
$title[$key] = preg_replace(''//b(''.implode(''|'', $keywords).'')/b(?![^<]*[>])/i'', ''<b>$0</b>'', $title[$key]);
$infoo[$key] = preg_replace(''//b(''.implode(''|'', $keywords).'')/b(?![^<]*[>])/i'', ''<b>$0</b>'', $infoo[$key]);
echo ''<tr><td>''.$title[$key].$infoo[$key].$item.''</tr></td>'';
}

2º:

foreach ($linkai as $key => $linkas) {
$i++;
$a1 = $linkas[1];
$a2 = str_replace("download/", "files/", $a1);
$a3 = str_replace("&","&", $a2);
$a4 = str_replace("amp;nbsp;","nbsp;", $a3);
echo "<div class=/"bgframe".str_replace("/i/", "/IMG/", $a4)."</div></div>";
}

La pregunta es cómo hacer que esos dos bucles muestren resultados como este:

Result1 from Loop1
Result1 from Loop2
Result2 from Loop1
Result2 from Loop2
Result3 from Loop1
Result3 from Loop2
And so on...

En lugar de:

Result1 from Loop1
Result2 from Loop1
Result3 from Loop1
...
Result1 from Loop2
Result2 from Loop2
Result3 from Loop2

Gracias

La solución obvia:

$output1 = array();
$output2 = array();
foreach ($items as $key => $item)
{
$keywords = explode('' '', $qsvarus);
$title[$key] = preg_replace(''//b(''.implode(''|'', $keywords).'')/b(?![^<]*[>])/i'', ''<b>$0</b>'', $title[$key]);
$infoo[$key] = preg_replace(''//b(''.implode(''|'', $keywords).'')/b(?![^<]*[>])/i'', ''<b>$0</b>'', $infoo[$key]);
$output1[] = ''<tr><td>''.$title[$key].$infoo[$key].$item.''</tr></td>'';
}
foreach ($linkai as $key => $linkas) {
$i++;
$a1 = $linkas[1];
$a2 = str_replace("download/", "files/", $a1);
$a3 = str_replace("&","&amp;", $a2);
$a4 = str_replace("amp;nbsp;","nbsp;", $a3);
$output2[] = "<div class=/"bgframe".str_replace("/i/", "/IMG/", $a4)."</div></div>";
}
$output = array_map( null, $output1, $output2 );
foreach ( $output as $lines ) {
$lines = array_filter( $lines );
foreach ( $lines as $line ) {
echo $line;
}
}

La mejor respuesta es probablemente de Jack, pero pensé que mi solución era interesante. También intenté mejorar tu código:

do {
if ($item = current($items)) {
$key = key($items);
$keywords = str_replace('' '', ''|'');
list($infoo_str, $title_str) = preg_replace(
"//b({$keywords})/b(?![^<]*[>])/i",
''<b>$0</b>'',
array($infoo[$key], $title[$key])
);
echo "<tr><td>{$infoo_str}{$title_str}{$item}</tr></td>";
next($items);
}
if ($linkas = current($linkai)) {
$characters = array(''download/'', ''&'', ''amp;nbsp;'', ''/i/'');
$replacements = array(''files/'', ''&amp;'', ''&nbsp;'', ''/IMG/'');
$linkas = str_replace($characters, $replacements, $linkas);
echo "<div class=''bgframe{$linkas}''</div></div>";
next($linkai);
}
} while ($item or $linkas);

Puede usar MultipleIterator para esto:

$m = new MultipleIterator();
$m->attachIterator(new ArrayIterator($items), ''item'');
$m->attachIterator(new ArrayIterator($linkai), ''linkas'');
foreach ($m as $unit) {
// $unit[''item''] contains an entry from $items
// $unit[''linkas''] contains an entry from $linkai
// your logic here
}
