Question

我们想知道，我们如何使用数组（关键字）检查数组（数据）。我们希望将结果存储到变量中以供进一步使用。在这里我们详细解释你。

$array1 = array(John Wilkins, Poul Warner, Rodger Smith, David Bentham, David Wilkins, Brian Smith, David Warner)(Data)

$array2 = array(Wilkins, Warner, Smith, Bentham)(Keywords)

这里我们要检查array1中的array2。并将结果存储在变量中，并在以后或最后打印出来。

Checking Process will be....... 
Array2(Wilkins) checks all the items in Array1.
Array2(Warner) checks all the items in Array1.
Array2(Smith) checks all the items in Array1.
and so on...

请帮助解决此问题..

Answer 1

这样的事情怎么样：

$matches = array();

foreach ( $array2 as $value2 )
  foreach ( $array1 as $value1 )
    if ( stripos($value1, $value2) !== FALSE )
      $matches[] = $value1;

// Just in case a record matched more than once.
$matches = array_unique($matches);

Answer 2

$array1 = array("John Wilkins", "Poul Warner", "Rodger Smith", "David Bentham", "David Wilkins", "Brian Smith", "David Warner");
$array2 = array("Wilkins", "Warner", "Smith", "Bentham");
$result = array();

foreach ( $array2 as $value ) {
    $result = array_merge( preg_grep("/$value/", $array1), $result );
}

$result = array_unique($result);

print_r($result);

输出：

Array
(
    [0] => David Bentham
    [1] => Rodger Smith
    [2] => Brian Smith
    [3] => Poul Warner
    [4] => David Warner
    [5] => John Wilkins
    [6] => David Wilkins
)

数组检查Duplicacy和Unique值，并打印它们
