问题 I have a regular expression that Im using in php: $word_array = preg_split( '/(\/|\.|-|_|=|\?|\&|html|shtml|www|php|cgi|htm|aspx|asp|index|com|net|org|%|\+)/', urldecode($path), NULL, PREG_SPLIT_NO_EMPTY ); It works great.

The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English.

I couldn't find any relevant example on the PHP preg_split page, that's why I am asking. 回答1: Try this: <?php $string = "foo bar baz; boo, bat"; $words = preg_split('/[,.\s;]+/', $string); var_dump($words); // -> ["foo", "bar", "baz", "boo", "bat"] The Pattern explained [] is a character class, a character class
