[英]Special characters (utf-8) in PHP contact message
我有聯系表格。 當我收到一條消息時,我無法正常閱讀,因為特殊字符會顯示出來。
我在utf-8中保存了我的文件,沒有BOM,我紅了,嘗試了很多關於這個主題的變化,但我找不到適合自己的答案。
我的html中的聯系表單:
<meta charset="utf-8" />
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<form id="contactform" action="processform.php" method="post" accept-charset='UTF-8'>
<div class="form-label label-name">Nom</div>
<input type="text" name="name" id="name" />
<div class="form-label label-postcode">Code Postal</div>
<input type="text" name="postcode" id="postcode" />
<div class="form-label label-email">E-mail</div>
<input type="text" name="email" id="email" />
<div class="form-label label-subject">Sujet</div>
<input type="text" name="subject" id="subject" />
<div class="form-label label-message">Message</div>
<textarea rows="4" name="message" id="message"></textarea>
<input type="submit" id="send" name="button" value="Envoyer" />
</form>
我的processform.php文件(以無BOM的UTF-8保存)具有以下代碼:
<?php
include_once $_SERVER['DOCUMENT_ROOT'] . '/securimage/securimage.php';
$securimage = new Securimage();
if ($securimage->check($_POST['verif']) == false) {
// the code was incorrect
// you should handle the error so that the form processor doesn't continue
// or you can use the following code if there is no validation or you do not know how
echo "Le code de sécurité indiqué est incorrect.<br />";
echo "Rafraîchissez la page et essayez à nouveau svp.";
exit;
}
// Clean up the input values
foreach($_POST as $key => $value) {
if(ini_get('magic_quotes_gpc'))
$_POST[$key] = stripslashes($_POST[$key]);
$_POST[$key] = htmlspecialchars(strip_tags($_POST[$key]));
}
// Assign the input values to variables for easy reference
$name = $_POST["name"];
$email = $_POST["email"];
$subject = $_POST["subject"];
$message = $_POST["message"];
// Test input values for errors
$errors = array();
if(strlen($name) < 3) {
if(!$name) {
$errors[] = "Entrez votre nom svp.";
} else {
$errors[] = "Au moins 3 caractères sont requis pour un nom.";
}
}
if(!$email) {
$errors[] = "Entrez votre email svp.";
} else if(!validEmail($email)) {
$errors[] = "Veuillez fournir une adresse valide svp.";
}
if(strlen($message) < 20) {
if(!$message) {
$errors[] = "Entrez un message svp.";
} else {
$errors[] = "Au moins 20 caractères sont requis pour un message.";
}
}
if($errors) {
// Output errors and die with a failure message
$errortext = "";
foreach($errors as $error) {
$errortext .= "<li>".$error."</li>";
}
die("<span class='failure'>Les erreurs suivantes sont survenues :<ul>". $errortext ."</ul></span>");
}
// Remplacement de certains caractères spéciaux
header('Content-Type: text/html; charset=utf-8');
// Send the email
$to = "myemail@gmail.com";
$message = "
From: $name
Email: $email
Subject: $subject
Message: $message";
$headers = "Message from West Hungary website";
mail($to, $subject, $message, $headers);
// Die with a success message
die("<span class='success'>Votre message a été envoyé avec succès !</span>");
// A function that checks to see if
// an email is valid
function validEmail($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;
}
?>
嘗試將此行添加到標題中,
$headers = 'MIME-Version: 1.0\r\n';
$headers .= "Content-Type: text/html; charset=UTF-8\n";
1 - 確保在HTML頭中有這個:
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
2 - 然后將其添加到PHP腳本的開頭:
header('Content-Type: text/html; charset=utf-8');
前兩個步驟的示例:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8"
<title>PHP Special Characters</title>
</head>
<body>
<?php
$header= "MIME-Version: 1.0\r\n";
$header.= "Content-type: text/html; charset=iso-8859-1\r\n";
echo "àè";
?>
</body>
</html>
對於步驟2,您可以將其添加到.htaccess文件中:
AddDefaultCharset UTF-8
如果以上都不起作用,請在PHP代碼中使用它(確保設置正確的位置):
setlocale(LC_ALL, 'fr_CA.utf-8');
您可以嘗試使用此PHP函數轉換要顯示的文本。 它將UTF8編碼的字符串作為參數,並返回以ISO-8859-1字符轉換的字符串
utf8_decode($your_text)
由於您使用的是UTF-8,請考慮使用php多字節函數鏈接mb_
*。 例如:
echo strlen('è'); // output 2
echo mb_strlen('è', 'UTF-8'); // output 1
您可能感興趣的其他mb_ *函數:
strrpos()
到mb_strrpos()
substr()
到mb_substr()
有關多字節功能的完整列表,請查看此處 。
如果您不想在每個mb_函數中傳遞'UTF-8',請在腳本的開頭調用mb_internal_encoding('UTF-8')
。
要使mail()
函數與UTF-8一起正常工作,請在標題中傳遞以下內容:
$header = "Content-Type: text/html; charset=UTF-8"
