我有一个功能,将添加< a href>链接前的标签和< / a>之后的链接.但是,对于某些网页而言,它会中断.你如何改善这个功能？谢谢！
function processString($s)
{
// check if there is a link
if(preg_match("/http:\/\//",$s))
{
print preg_match("/http:\/\//",$s);
$startUrl = stripos($s,"http://");
// if the link is in between text
if(stripos($s," ",$startUrl)){
$endUrl = stripos($s,$startUrl);
}
// if link is at the end of string
else {$endUrl = strlen($s);}
$beforeUrl = substr($s,$startUrl);
$url = substr($s,$startUrl,$endUrl-$startUrl);
$afterUrl = substr($s,$endUrl);
$newString = $beforeUrl."<a href=\"$url\">".$url."</a>".$afterUrl;
return $newString;
}
return $s;
}
function processString($s) {
return preg_replace('/https?:\/\/[\w\-\.!~#?&=+\*\'"(),\/]+/','<a href="$0">$0</a>',$s);
}
