php - 如何在 PHP 中使用正则表达式匹配字符串中的任何单词

Question

我有这些字符串。我想要一个正则表达式来匹配它们并在将它们传递给 preg_match 函数时返回 true。

do you want to eat katak at my hometown?
do you want to eat teloq at my hometown?
do you want to eat tempeyek at my hometown?
do you want to eat karipap at my hometown?

如何在正则表达式中创建匹配上述模式的模式？像这样:

do you want to eat * at my hometown?

星号 (*) 表示任何单词。这是我目前拥有的正则表达式模式:

$text = "do you want to eat meatball at my hometown?";
$pattern = "/do you want to eat ([a-zA-Z0-9]) at my hometown?/i";

if (preg_match($pattern, $text)) {
    echo "A match was found.";
} else {
    echo "A match was not found.";
}

([a-zA-Z0-9]) 格式与单词不匹配。如何匹配单词上的字符串？

Answer 1

使用量词:

$pattern = "/do you want to eat ([a-z0-9]*) at my hometown\?/i";
//                                here __^

并转义 ? ==> \?
