combine two foreach loops

Question

I have two foreach loops: 1st one:

        foreach ($items as $key => $item) 
        {   
        $keywords = explode(\' \', $qsvarus);
        $title[$key]          


        

Answer 1

The obvious solution:

$output1 = array();
$output2 = array();

foreach ($items as $key => $item) 
{   
    $keywords = explode(' ', $qsvarus);
    $title[$key] = preg_replace('/\b('.implode('|', $keywords).')\b(?![^<]*[>])/i', '$0', $title[$key]);
    $infoo[$key] = preg_replace('/\b('.implode('|', $keywords).')\b(?![^<]*[>])/i', '$0', $infoo[$key]);
    $output1[] = ''.$title[$key].$infoo[$key].$item.'';
}

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);
    $output2[] = "
";
}

$output = array_map( null, $output1, $output2 );
foreach ( $output as $lines ) {
    $lines = array_filter( $lines );
    foreach ( $lines as $line ) {
        echo $line;
    }
}
