Question

所以我试图拆分包含电话号码和分机号的字符串，因为有时字符串中存在扩展名。这是我的尝试：

$tests[] = "941-751-6550 ext 2204";
$tests[] = "(941) 751-6550 ext 2204";
$tests[] = "(941)751-6550 ext 2204";
$tests[] = "9417516550 ext 2204";
$tests[] = "941-751-6550 e 2204";
$tests[] = "941-751-6550 ext 2204 ";
$tests[] = "941-751-6550 extension 2204";
$tests[] = "941-751-6550 x2204";
$tests[] = "(941) 751-6550";
$tests[] = "(941)7516550";
$tests[] = "941-751-6550 ";
$tests[] = "941-751-6550";

foreach ($tests as $test) {
    preg_match('#([\(\)\s0-9\-]+)(.+$)#',$test,$matches);
    $phone = preg_replace('#[\-\(\)\s]#','',$matches[1]);
    $extension = preg_replace('#[^0-9]#','',$matches[2]);
    if ($phone == '9417516550' 
        && ($extension == '2204' 
            || $extension == '0')) {
                echo "PASS: phone: $phone ext: $extension<br />";
    } else {
        echo "FAIL: phone: $phone ext: $extension<br />";
    }
}

但是，当我运行这些测试以查看它是否正确拆分电话号码和分机时，我得到以下输出：

PASS: phone: 9417516550 ext: 2204
PASS: phone: 9417516550 ext: 2204
PASS: phone: 9417516550 ext: 2204
PASS: phone: 9417516550 ext: 2204
PASS: phone: 9417516550 ext: 2204
PASS: phone: 9417516550 ext: 2204
PASS: phone: 9417516550 ext: 2204
PASS: phone: 9417516550 ext: 2204
FAIL: phone: 941751655 ext: 0
FAIL: phone: 941751655 ext: 0
FAIL: phone: 9417516550 ext: 
FAIL: phone: 941751655 ext: 0

正如您所看到的，当我完全排除一个扩展（最后四个测试）时，它会中断。我如何更正preg_match()正则表达式，以便FAIL: ...行看起来像PASS: phone: 9417516550 ext: 0？

Answer 1

(.+$)表示在一行的末尾必须是1个或多个符号。因此，如果您在电话号码后面没有任何内容 - 那么您的电话号码将减少1个符号。

我建议使用(.*$)，这意味着零个或多个符号。

Answer 2

我会在preg_match中完成所有操作。假设这些数字是非国际性的，我认为这样可行。

foreach ($tests as $test) {
    preg_match('#\(?(\d{3})\)?[-\h]?(\d{3})[-\h]?(\d{4})\h*(?:e?x?t?(?:ension)?\h(\d+))?#',$test,$matches);
    $phone = $matches[1] . $matches[2] . $matches[3];
    $extension = !empty($matches[4]) ? $matches[4] : 0;
    if ($phone == '9417516550' 
        && ($extension == '2204' || $extension == '0')) {
            echo "PASS: phone: $phone ext: $extension<br />";
    } else {
         echo "FAIL: phone: $phone ext: $extension<br />";
    }
}

这可以按预期工作，只是经过测试。

foreach ($tests as $test) {
    preg_match('#([\(\)0-9\-]+\s*[\(\)0-9\-]+)\s*(.*$)#',$test,$matches);
    $phone = preg_replace('#[\-\(\)\s]#','',$matches[1]);
    $extension = ($matches[2] == "") ? '0' : preg_replace('#[^0-9]#','',$matches[2]);
    if ($phone == '9417516550'
        && ($extension == '2204'
            || $extension == '0')) {
                echo "PASS: phone: $phone ext: $extension<br />\n";
    } else {
        echo "FAIL: phone: $phone ext: $extension<br />\n";
    }
}

对代码进行微小更改。

Answer 4

从你的例子来看，当没有任何东西被发现时，它似乎失败了。

解决方案是像这样转换为int $extension：

$extension = intval($extension); //If nothing found will be 0

在此之后我们确信我们有一个integer，我们可以将if语句更改为：

|| $extension === 0)) {

$pns = <<< LOL

preg_match_all('/^([(\d )\-]+)\s?(?:e.*?|x.*?)?(\d+)?$/sim', $pns, $matches, PREG_PATTERN_ORDER);
for ($i = 0; $i < count($matches[1]); $i++) {
    $phone = preg_replace('#[\-\(\)\s]#','', $matches[1][$i]);
    $extension = preg_replace('#[^0-9]#','', $matches[2][$i]);
    if ($phone == '9417516550' && $extension == '2204') {
             echo "PASS: phone: $phone ext: $extension\n";
    } else {
             echo "FAIL: phone: $phone ext: 0\n";
    }
}

老实说，你最好剥离非数字字符，然后在前10个之后将任何东西拆分为扩展名。它在概念上是等效的，但比直接运行多个正则缓慢的正则数据更简单，更安全，更高效。

foreach($tests as $test){
    $phone = preg_replace("/[^0-9]/", "", $test);
    $extension = substr($phone,10);
    $phone = substr($phone,0,10);
    if(empty($extension)){
         $extension = '0';
    }
    if ($phone == '9417516550'
        && ($extension == '2204'
            || $extension == '0')) {
                echo "PASS: phone: $phone ext: $extension<br />\n";
    } else {
        echo "FAIL: phone: $phone ext: $extension<br />\n";
    }
}

输出：

PASS: phone: 9417516550 ext: 2204
PASS: phone: 9417516550 ext: 2204
