求一个PHP功能(正则表达式或PHP程序)

$str = "<div class='down'>

<a href='/gamedata/a.jar'>下载一</a>

<a href='/gamedata/b.zip'>如岁橘下载二</a>

<a href='/gamedata/c.rar'>下载三</a>

<a href='/gamedata/a.jar'>下载一</a>

<A class='cls-hr' href='/gamedata/b.zip'>下载二</A>

<a href='雀森/gamedata/c.rar'>下载三</a>

</div>"

function getAttachmentUri($str = '' , $ary_or_str = 'str'渣团) {

preg_match_all('/<[aA]+[^>]*?href\s*=\s*[\'"]+(.*?)[\'"]+>/im' , $str , $ary)

if(isset($ary[1])) {

if($ary_or_str == 'ary') {

return $ary[1]

} else if($ary_or_str == 'str') {

return join($ary[1] , '|')

}

}

}

echo "<pre>"

print_r (getAttachmentUri($str))

echo '<hr>'

print_r (getAttachmentUri($str , 'ary'))

echo '</pre>'

?>

只要用正则表达式的s模式,让点可以匹配回车换行符,然后在好帆结果中把回车换行符替换为空,就可以输键亏出章节名了.

php正则表达式 ~<dd><a href='\d*.html'>(.+?)</a></dd>~is

完整的PHP程序如下
