用到2个函数 preg_replace, iconv

https://php.net/manual/en/function.iconv.php
https://www.php.net/manual/en/function.preg-replace.php
参考php官网的示例
example #2 using indexed arrays with preg_replace()<?php$string = 'the quick brown fox jumps over the lazy dog.';$patterns = array();$patterns[0] = '/quick/';$patterns[1] = '/brown/';$patterns[2] = '/fox/';$replacements = array();$replacements[2] = 'bear';$replacements[1] = 'black';$replacements[0] = 'slow';echo preg_replace($patterns, $replacements, $string);?>example #1 iconv() example<?php$text = "this is the euro symbol '€'.";echo 'original : ', $text, php_eol;echo 'translit : ', iconv("utf-8", "iso-8859-1//translit", $text), php_eol;echo 'ignore : ', iconv("utf-8", "iso-8859-1//ignore", $text), php_eol;echo 'plain : ', iconv("utf-8", "iso-8859-1", $text), php_eol;?>
