My page is utf-8, the page of file_get_contents is gb2312, and the Chinese characters are garbled when output.
The solution is as follows:
Copy code
<?php
header("Content-Type:text/html;charset=utf-8");
$keyworld="煤层";
$keyworld=iconv("utf-8","gb2312",$keyworld);
$url = "http://www.baidu.com/s?f=8&wd=$keyworld";
$html = file_get_contents($url);
$html = iconv("gb2312", "utf-8//IGNORE",$html);
echo $html;
?> 1. Introduction to iconv()
The iconv function can convert a known character set file into another known character set file. For example: Convert from GB2312 to UTF-8.
The iconv function is built in php5, and the GB character set is turned on by default.
2. iconv() error
iconv will make an error when converting the character "-" to gb2312. The solution is to add "//IGNORE" after the encoding to be converted, that is, after the second parameter of the iconv function. As follows:
iconv("UTF-8", "GB2312//IGNORE", $data)Ignore means to ignore errors during conversion. Without the ignore parameter, all strings following this character cannot be saved.
3. iconv() example
Example 1:
<?php
$str = "你好,这里是卖咖啡!";
echo '<br />';
echo iconv('GB2312', 'UTF-8', $str); //将字符串的编码从GB2312转到UTF-8
echo '<br />';
echo iconv_substr($str, 1, 1, 'UTF-8'); //按字符个数截取而非字节
print_r(iconv_get_encoding()); //得到当前页面编码信息
echo iconv_strlen($str, 'UTF-8'); //得到设定编码的字符串长度
?>
