PHP字符串拆分

Question

$var=<a href="/abcd/100th-indian-science-congress">100th Indian Science Congress</a>;

在上面我只是想连接“ 100th-indian-science-congress ”所以请帮我解决这类问题

Answer 1

$result = str_replace(" ", "-", $var);

Answer 2

preg_match ('/a href="(.*?)"/', $var, $matches);

结果应该是$ matches [1];

Answer 3

<?php
  $var= '<a href="/abcd/100th-indian-science-congress">100th Indian Science Congress</a>';  

  $url = preg_match('/<a href="(.+)">/', $var, $match);
  $outcome = basename($match[1]);
?>
