在第一次出现 html 标记时拆分字符串

Question

How can I split a string into 2 variables at first occurrence of a specific html tag (section in this case)?

$str = 'some text, <b>some text</b> <section class="first">abc</sextion><section class="second">abc</section> some text';

$first = 'some text, <b>some text</b> ';
$second = '<section class="first">abc</sextion><section class="second">abc</section> some text';

Answer 1

Use preg_split

preg_split('~(?=<section\b)~', $str, 2)

Third paramter 2 specifies the no of items would be returned after splitting. So this would give you only two parts.
