How can I convert ereg expressions to preg in PHP?
My contact form is othervise working but I keep getting the following error:
我的联系表格可以正常工作，但我不断收到以下错误：
Deprecated: Function ereg() is deprecated in/home/.....
已弃用：函数 ereg() 在/home/..... 中已弃用
I'm really lost here but I figure this is the part that needs some adjusting.
我真的迷失在这里，但我认为这是需要一些调整的部分。
if ( empty($_REQUEST['name']) ) {
$pass = 1;
$alert .= $emptyname;
} elseif ( ereg( "[][{}()*+?.\^$|]", $_REQUEST['name'] ) ) {
$pass = 1;
$alert .= $alertname;
}
if ( empty($_REQUEST['email']) ) {
$pass = 1;
$alert .= $emptyemail;
} elseif ( !eregi("^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z] {2,3})$", $_REQUEST['email']) ) {
$pass = 1;
$alert .= $alertemail;
}
if ( empty($_REQUEST['message']) ) {
$pass = 1;
$alert .= $emptymessage;
} elseif ( preg_match( "[][{}()*+?\^$|]", $_REQUEST['message'] ) ) {
$pass = 1;
$alert .= $alertmessage;
}
Finding a solution would be highly appreciated

You must use preg_matchinstead of eregbecause the last one is deprecated.
您必须使用preg_match而不是ereg因为最后一个已被弃用。
Replacing it is not a big deal:
更换它不是什么大问题：
ereg( "[][{}()*+?.\^$|]", $_REQUEST['name'] )
will become:
会变成：
preg_match( "/[][{}()*+?.\^$|]/", $_REQUEST['name'] )
p.s. I had to modify more than one hundred files while I was porting my old project to PHP 5.3 to avoid manually modifying I've used following script to do it for me:
ps 在将旧项目移植到 PHP 5.3 时，我不得不修改一百多个文件以避免手动修改我使用以下脚本为我做这件事：
function replaceEregWithPregMatch($path) {
$content = file_get_contents($path);
$content = preg_replace('/ereg\(("|\')(.+)(\"|\'),/',
"preg_match('//',",
$content);
file_put_contents($path, $content);
}
I hope it helps.
我希望它有帮助。

The function ereg()is deprecated and should not be used any more. The documentationtells you what to do (to use preg_matchinstead).
该函数ereg()已被弃用，不应再使用。该文档告诉您要做什么（改为使用preg_match）。

Like you said - no bigie, it works like a charm:
就像你说的 - 没什么大不了的，它就像一个魅力：
if ( empty($_REQUEST['name']) ) {
$pass = 1;
$alert .= $emptyname;
} elseif ( preg_match( "/[][{}()*+?.\^$|]/", $_REQUEST['name'] ) ) {
$pass = 1;
$alert .= $alertname;
}
if ( empty($_REQUEST['email']) ) {
$pass = 1;
$alert .= $emptyemail;
} elseif ( !preg_match("#^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$#i", $_REQUEST['email']) ) {
$pass = 1;
$alert .= $alertemail;
}
if ( empty($_REQUEST['message']) ) {
$pass = 1;
$alert .= $emptymessage;
} elseif ( preg_match( "/[][{}()*+?\^$|]/", $_REQUEST['message'] ) ) {
$pass = 1;
$alert .= $alertmessage;
}
Thank you guys
谢谢你们
