Question

我有这个函数，我希望设置文本从文本返回一些匹配字符串：

function get_matches(){
    $string = "@text1 @text2 any text here #text3 #text4 @text5 ";
    // Set the test string.

    // Set the regex.
    $regex = 'WHAT IS THE REGEX HERE';

    // Run the regex with preg_match_all.
    preg_match_all($regex, $string, $matches);

    // Dump the resulst for testing.
    echo '<pre>';
    print_r($matches);
    echo '</pre>';

}

结果：

Array(
[0] => Array
    (
        [0] => text1
        [1] => text2
        [2] => text5
    ))

如何编写适当的正则表达式以获得正确的结果。

Answer 1

这个正则表达式适合你：

$regex = '/@(\S+)/';

输出：

Array
(
    [0] => Array
        (
            [0] => @text1
            [1] => @text2
            [2] => @text4
            [3] => @text5
        )

    [1] => Array
        (
            [0] => text1
            [1] => text2
            [2] => text4
            [3] => text5
        )

)

php在“@”字符后面的文本中获取所有匹配字符串
