Question

我有很多关于é，ô等特殊字符的描述，并试图将其删除：

$string = str_replace("é", " ", $string)
$string = ereg_replace("é", " ", $string)
$string = mysql_real_escape_string($string)

但没有任何作用，特殊字符仍然存在，并且描述未插入数据库中。我无法删除所有特殊字符，因为在描述中有所需的html标记。

感谢您的帮助！

Answer 1

http://www.php.net/manual/en/function.str-replace.php

此函数返回包含替换值的字符串或数组。

您需要使用返回值

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

Answer 2

轻松自负：

function clean($string) {
   $string = str_replace(' ', '-', $string); // Replaces all spaces with hyphens.
   return preg_replace('/[^A-Za-z0-9\-]/', '', $string); // Removes special chars.
}

<强>用法：

echo clean('a|"bc!@£de^&$f g');

将输出：abcdef-g

修改：

Hey, just a quick question, how can I prevent multiple hyphens from being next to each other? and have them replaced with just 1? Thanks in advance!

function clean($string) { $string = str_replace(' ', '-', $string); // Replaces all spaces with hyphens. $string = preg_replace('/[^A-Za-z0-9\-]/', '', $string); // Removes special chars. return preg_replace('/-+/', '-', $string); // Replaces multiple hyphens with single one. }

Answer 3

使用character transliteration。

示例：

<?php
$string = "ʿABBĀSĀBĀD";

echo iconv('UTF-8', 'ISO-8859-1//TRANSLIT//IGNORE', $string);
// output: ABBASABAD

?>

Answer 4

mysql_real_escape_string(htmlentities($string));
