Question

我需要在每个数组值的开头添加一个<p>标记，并在每个数组值的末尾添加一个结束</p>标记。

如果有[或]分隔符，则需要将其替换为<p class="myclass">

Array
(
    [0] => [This is a line of text
    [1] => and another
    [2] => and yet another.] [This is another line of text
    [3] => and another
    [4] => and another] [OK, so you get the idea.
)

上面的数组应该成为：

Array
(
    [0] => <p class="myclass">This is a line of text</p>
    [1] => <p>and another</p>
    [2] => <p>and yet another.</p> <p class="myclass">This is another line of text</p>
    [3] => <p>and another</p>
    [4] => <p>and another</p> <p class="myclass">OK, so you get the idea.</p>
)

问题是：使用foreach循环，如何从第一个数组到第二个数组？

Answer 1

$myArray = array(
    '[This is a line of text',
    'and another',
    'and yet another.] [This is another line of text',
    'and another',
    'and another] [OK, so you get the idea.',
);

array_walk($myArray,'pTagger');

function pTagger(&$value) {
    $value = str_replace(array('[',']'),array('<p class="myClass">','</p>'),$value);
    if (substr($value,0,2) !== '<p') $value = '<p>' . $value;
    if (substr($value,-4) !== '</p>') $value .= '</p>';
}

var_dump($myArray);

Answer 2

for($i = 0; $i < count($array); $i++) {
  $array[$i] = '<p>'.$array[$i].'</p>';
  $array[$i] = preg_replace('/\]/', '</p>', $array[$i]);
  $array[$i] = preg_replace('/\[/', '<p class="myclass">', $array[$i]);
  $array[$i] = preg_replace('/<p><p/', '<p', $array[$i]);
}
