PHP删除HTMl标签的三种解决方法_PHP
方法1:
直接取出想要取出的标记
复制代码 代码如下:
//取出br标记
function strip($str)
{
$str=str_replace("
","",$str);
//$str=htmlspecialchars($str);
return strip_tags($str);
}
?>
方法2.
PHP 中有个 strip_tags 函数可以方便地去除 HTML 标签。
echo strip_tags(“Hello World”); // 去除 HTML、XML 以及 PHP 的标签。
对于非标准的 HTML 代码也能正确的去除:
echo strip_tags(“\”>cftea”); //输出 cftea
在PHP中可以使用strip_tags函数去除HTML标签,看下面示例:
复制代码 代码如下:
$str = ‘www
dreamdu
.com';echo(htmlspecialchars($str).”
”);
echo(strip_tags($str));
?>
方法3.
strtr() 函数转换字符串中特定的字符。
语法
strtr(string,from,to)
或者
strtr(string,array)
参数 | 描述 |
---|---|
string1 | 必需。规定要转换的字符串。 |
from | 必需(除非使用数组)。规定要改变的字符。 |
to | 必需(除非使用数组)。规定要改变为的字符。 |
array | 必需(除非使用 from 和 to)。一个数组,其中的键是原始字符,值是目标字符。 |
例子1:
复制代码 代码如下:
echo strtr("Hilla Warld","ia","eo");
?>
例子2:
复制代码 代码如下:
$arr = array("Hello" => "Hi", "world" => "earth");
echo strtr("Hello world",$arr);
?>
