或者,当<代码>最大限度_execution_time被超越或是否成为过去的问题时,这一条才会终止?
I use the following code to validate emailaddresses on my sites (by Douglas Lovell):
function validate_email($email)
{
$isValid = true;
$atIndex = strrpos($email, "@");
if (is_bool($atIndex) && !$atIndex)
{
$isValid = false;
} else {
$domain = substr($email, $atIndex+1);
$local = substr($email, 0, $atIndex);
$localLen = strlen($local);
$domainLen = strlen($domain);
if ($localLen < 1 || $localLen > 64)
{
// local part length exceeded
$isValid = false;
}
else if ($domainLen < 1 || $domainLen > 255)
{
// domain part length exceeded
$isValid = false;
}
else if ($local[0] == . || $local[$localLen-1] == . )
{
// local part starts or ends with .
$isValid = false;
}
else if (preg_match( /\.\./ , $local))
{
// local part has two consecutive dots
$isValid = false;
}
else if (!preg_match( /^[A-Za-z0-9\-\.]+$/ , $domain))
{
// character not valid in domain part
$isValid = false;
}
else if (preg_match( /\.\./ , $domain))
{
// domain part has two consecutive dots
$isValid = false;
}
else if(!preg_match( /^(\\.|[A-Za-z0-9!#%&`_=\/$ *+?^{}|~.-])+$/ , str_replace("\\","",$local))) {
// character not valid in local part unless
// local part is quoted
if (!preg_match( /^"(\\"|[^"])+"$/ , str_replace("\\","",$local))) {
$isValid = false;
}
}
if ($isValid && !(checkdnsrr($domain,"MX") || checkdnsrr($domain,"A")))
{
// domain not found in DNS
$isValid = false;
}
}
return $isValid;
}
