$content = str_replace('#p#副标题#e#','',$body);
$content = str_replace('请看下一页', '',$body);
$content = str_replace('/uploads', 'http://www.****.com/uploads',$body);

各位，我想输出的$body读取的内容，同时替换掉里面的“#p#副标题#e#” “'请看下一页” “/uploads”

请问怎么实现呀？现在只能替换最后一个语句的，3个不能同时被替换

回复讨论(解决方案)

$body =<<< 'TXT'各位，我想输出的$body读取的内容，同时替换掉里面的“#p#副标题#e#”  “'请看下一页”  “/uploads”TXT;$body = str_replace('#p#副标题#e#','',$body);$body = str_replace('请看下一页', '',$body);$body = str_replace('/uploads', 'http://www.****.com/uploads',$body);echo $body;

写成这样更简捷

body =<<< 'TXT'各位，我想输出的$body读取的内容，同时替换掉里面的“#p#副标题#e#”  “'请看下一页”  “/uploads”TXT;$p = array('#p#副标题#e#', '请看下一页', '/uploads');$r = array('','', 'http://www.****.com/uploads');echo str_replace($p, $r, $body);

header("Content-type: text/html; charset=utf-8");$body = <<<BODY#p#副标题#e#请看下一页/uploadsBODY;//$content = str_replace('#p#副标题#e#','',$body);//$content = str_replace('请看下一页', '',$body);//$content = str_replace('/uploads', 'http://www.****.com/uploads',$body);echo "替换前的内容：" . "<br/>" . $body . "<br/>" . "<hr/>";$arr_orignal_content = array ('#p#副标题#e#', '请看下一页', '/uploads');$arr_replace_content = array ('', '', 'http://www.baidu.com/uploads');$body = str_replace($arr_orignal_content, $arr_replace_content, $body);echo "替换后的内容：" . "<br/>" . $body;

楼上的都是正解

可以用正则，把这三个拼成一个正则即可

第一次替?完后，就不要用$body了，而是用$content?行后面的替?。

$content = str_replace('#p#副标题#e#','',$body);$content = str_replace('请看下一页', '',$content);$content = str_replace('/uploads', 'http://www.****.com/uploads',$content);
