PHP如何把字符串改成UTF8?
在PHP中可以使用“iconv()”函数把字符串改成UTF8,该函数作用是将字符串按要求的字符编码来转换,其语法为“iconv(in,out,str)”,使用时将in设置为字符串的编码,out设置为UTF8,str设置为要转换的字符串即可。
转化示例
$str = "123456789";$str = iconv('ASCII', 'UTF8', $str);
使用示例
<?php//some German$utf8_sentence = 'Weiß, Goldmann, Göbel, Weiss, Göthe, Goethe und Götz';//UKsetlocale(LC_ALL, 'en_GB');//transliterate$trans_sentence = iconv('UTF-8', 'ASCII//TRANSLIT', $utf8_sentence);//gives [Weiss, Goldmann, Gobel, Weiss, Gothe, Goethe und Gotz]//which is our original string flattened into 7-bit ASCII as//an English speaker would do it (ie. simply remove the umlauts)echo $trans_sentence . PHP_EOL;//Germanysetlocale(LC_ALL, 'de_DE');$trans_sentence = iconv('UTF-8', 'ASCII//TRANSLIT', $utf8_sentence);//gives [Weiss, Goldmann, Goebel, Weiss, Goethe, Goethe und Goetz]//which is exactly how a German would transliterate those//umlauted characters if forced to use 7-bit ASCII!//(because really ä = ae, ö = oe and ü = ue)echo $trans_sentence . PHP_EOL;?>
<?php$tab = array("UTF-8", "ASCII", "Windows-1252", "ISO-8859-15", "ISO-8859-1", "ISO-8859-6", "CP1256");$chain = "";foreach ($tab as $i) { foreach ($tab as $j) { $chain .= " $i$j ".iconv($i, $j, "$my_string"); } }echo $chain;?>
