然后

http://www.php.net/manual/en/function.in-array.php

in_array( 'theword', array_merge ( $array1, $array2, $array3 ) );

Answer 3

if(in_array('certain word', array_merge($array1, $array2, $array3))
{
    echo 'Found a match';
}

Answer 4

$combined = array_map(function ($a1, $a2, $a3) { return "$a1 - $a2 - $3"; }, $array1, $array2, $array3);
foreach ($combined as $string) {
    if (strpos($string, 'some word') !== false) {
        echo "'$string' contains 'some word'";
    }
}

如果我的问题正确，我相信这就是你想要实现的目标

final_array=array();
foreach ($arr1 as $key=>$value)
{
    final_array[$key]=final_array[$key].$value;
}

foreach ($arr2 as $key=>$value)
{
    final_array[$key]=final_array[$key].$value;
}

foreach ($arr3 as $key=>$value)
{
    final_array[$key]=final_array[$key].$value;
}

foreach ($final_array as $key=>$value)
{
    if(strstr($value,$search_keyword))
    {
        echo "match found for :$search_keyword" 
    }

}
