找到并替换php中的字符串

Question

我通过foreach循环获得了一些值。现在我想用一个字符串检查每个值。

我的字符串是"http://www.example.com/TantraProjects/Ranjit/nt_plugin"

我喜欢写在下面的值：

http://blogsearch.google.com/blogsearch?scoring=d&partner=wordpress&q=link:http://www.example.com/TantraProjects/Ranjit/nt_plugin/ 

http://blogsearch.google.com/blogsearch_feeds?scoring=d&ie=utf-8&num=10&output=rss&partner=wordpress&q=link:http://www.example.com/TantraProjects/Ranjit/nt_plugin/ 

link:http://www.example.com/TantraProjects/Ranjit/nt_plugin/ - Google Blog Search 

现在我想改变这一切的价值观，与MY NEW PATH更换http://www.example.com/TantraProjects/Ranjit/nt_plugin。

我该如何使用php替换字符串？

Answer 1

str_replace

而且请使用谷歌，有数以千计的这个问题的答案在网上。 :)

此外，如果你要嵌入的链接在这样的网址：

http://blogsearch.google.com/blogsearch?scoring=d&partner=wordpress&q=link:http://www.example.com/TantraProjects/Ranjit/nt_plugin/

你需要在你&q=后通过URL使用urlencode。

所以基本上：

$string = "http://blogsearch.google.com/blogsearch?scoring=d&partner=wordpress&q=MY_NEW_PATH"; 
$output = str_replace('MY_NEW_PATH', "link:".urlencode('http://www.example.com/TantraProjects/Ranjit/nt_plugin'), $string); //$search , $replace, $subject 

Answer 2

可能通过使用str_replace这样的：

$findstr = "http://www.example.com/TantraProjects/Ranjit/nt_plugin"; 
$newstr = "new string here"; 
$newlist = array(); 

foreach($list as $item) 
{ 
    $newlist[] = str_replace($findstr, $newstr, $item); 
}
