可以寫一個(gè)函數(shù)將相對(duì)路徑變成絕對(duì)路徑就行拉 比如說(shuō)：

function?format_url($srcurl,?$baseurl)?{??
??$srcinfo?=?parse_url($srcurl);??
??if(isset($srcinfo['scheme']))?{??
????return?$srcurl;??
??}??
??$baseinfo?=?parse_url($baseurl);??
??$url?=?$baseinfo['scheme'].'://'.$baseinfo['host'];??
??if(substr($srcinfo['path'],?0,?1)?==?'/')?{??
????$path?=?$srcinfo['path'];??
??}else{??
????$path?=?dirname($baseinfo['path']).'/'.$srcinfo['path'];??
??}??
??$rst?=?array();??
??$path_array?=?explode('/',?$path);??
??if(!$path_array[0])?{??
????$rst[]?=?'';??
??}??
??foreach?($path_array?AS?$key?=>?$dir)?{??
????if?($dir?==?'..')?{??
??????if?(end($rst)?==?'..')?{??
????????$rst[]?=?'..';??
??????}elseif(!array_pop($rst))?{??
????????$rst[]?=?'..';??
??????}??
????}elseif($dir?&&?$dir?!=?'.')?{??
??????$rst[]?=?$dir;??
????}??
???}??
??if(!end($path_array))?{??
????$rst[]?=?'';??
??}??
??$url?.=?implode('/',?$rst);??
??return?str_replace('\\',?'/',?$url);??
}?

$a?=?'http://shijinrong.cn';??
$b?=?'/home/article/tags.html';??

echo?format_url($b,?$a);
