使用eregi（）帮助进行电子邮件地址验证 [英] Help with email address validation using eregi()
问题描述
嗨
以下脚本取自John Coggeshall（PHP顾问）在Zends网站上的文章 http://www.zend.com/zend/spotlight/ev12apr.php
//获取要验证的电子邮件地址
$ email = $ _POST [''email'']
/ /使用John Coggeshalls脚本验证电子邮件地址
if（！eregi（" ^ [_ a-z0-9 - ] +（\。[_ a-z0-9 - ] +）* @ [a-z0-9 - ] +（\。[a-z0-9-
] +）*（\。[az] {2,3}）$"， $ email）{
echo电子邮件无效;
}
else {
echo电子邮件是有效的;
}
在第一个例子中，如果我将脚本复制并粘贴到我的脚本中，脚本将不起作用
php文件。我得到一个解析错误信息。
在第二个例子中，有许多与脚本相关的帖子
有效性它仍然允许无效的电子邮件地址。
所以我有3个问题。
1）为什么我得到解析错误信息？
2）是否有确定的电子邮件验证脚本？
3）我在哪里可以找到正则表达式或其他表单验证脚本
验证电话号码，邮政编码等内容，不包含的名字
数字字符等等
亲切的问候

Hi
The following script was taken from John Coggeshall''s (PHP consultant) in his
article on Zends site at http://www.zend.com/zend/spotlight/ev12apr.php
// Get the email address to validate
$email = $_POST[''email'']
// Use John Coggeshalls script to validate the email address
if(!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-
]+)*(\.[a-z]{2,3})$", $email) {
echo "The e-mail was not valid";
}
else {
echo "The e-mail was valid";
}
In the first instance the script does not work if I copy and paste it into my
php file. I get a parse error message.
In the second instance, there are many postings relating to the scripts
effectiveness in that it will still allow email addresses that are invalid.
So I have 3 questions.
1) Why do I get the parse error message?
2) Is there a definitive email validation script?
3) Where can I find regular expressions or other form validation scripts to
validate things such as telephone numbers, postcodes, names that don''t contain
numeric characters etc etc
Kind regards
