在PHP中从字符串中删除字符串的一部分

我做了一些工作,我从Google API搜索结果片段中获取了一个字符串.在这个字符串中包含,这为进一步的工作带来了问题,所以我需要删除和

主要字符串代码:

$content_all .="#$*@#" . $json->responseData->results[$x]->content;

我尝试此代码后删除和:

 $content_all=(string)$content_all;
str_replace("", " ", $content_all);
str_replace("", " ", $content_all);

但它不会删除和.我试过了

str_replace("hello", " ", "Hello people");

它奏效了.但为什么它不适合$content_all刺痛.我写了$ content_all的值,它看起来像这样

如果你想从字符串中删除html标签你可以去strip_tags()

例如:

   world!");//Hello world
   ?>

小心strip_tag将删除字符串中的所有标记.

请参阅http://www.w3schools.com/php/func_string_strip_tags.asp.

如果你使用str_replace("", " ", $content_all);它还有一件事它会给你不想要的空间

ie:str_replace("", " ", "hi 

 vig");
result: hi      vig

$content_all=str_replace("", " ", $content_all);
$content_all=str_replace("", " ", $content_all);

echo $content_all;

   world!");//Hello world
   ?>

ie:str_replace("", " ", "hi 

 vig");
result: hi      vig

$content_all=str_replace("", " ", $content_all);
$content_all=str_replace("", " ", $content_all);

echo $content_all;
