我想搜索/允许字符和空格。 这适用于ANSI / LATIN-1字符:
$pattern = '#<a [\W\w]* href="1"#i';
我试过这个,但显然它不起作用:
mb_internal_encoding('UTF-8');
mb_regex_encoding("UTF-8");
$pattern = '/<a[\pLN\W]* href="1"/ui';
答案 0 :(得分:1)
使用此代替
$pattern = '~<a [\pL\s]*\bhref="1"~ui';
<a #begin with a tag + a space
[\pL\s]* # zero or more unicode letters or blank characters (space newline tab)
\bhref="1" # href="1" not preceded by a letter or a number
ui # modifier u for unicode string, i case insensitive
