我有脚本在页面php的值和txt文件中的数据存储之间进行比较，然后它会做一些特殊的代码。
txt文件的内容（account.txt）
F: user pass { expire=date; afexpire=date; email=email@gmail.com; Country=Germani; visit_from=none; ip=none; hosted=none }
F: mike fghg58g { expire=2016-05-24; afexpire=2015-5-24 17; email=mike@gmail.com; Country=uk; visit_from=none; ip=none; hosted=none }
F: adresson f5849dh9d { expire=2016-11-01; afexpire=2015-11-01 17; email=mike@gmail.com; Country=Germani; visit_from=none; ip=none; hosted=none }
我的剧本
<?php
$user = "Mike"; // user that is inserted in page form
$email = "mike@gmail.com"; // email that is inserted in page form
$userFile = "Mike"; // user in txt file
$emailFile = "mike@gmail.com"; // email in txt file
if( $user == $userFile && $email == $emailFile ) {
echo "The user and email is used";
} elseif( $user == $userFile && $email != $emailFile ) {
echo "The user is used";
} else{
// do special code
}
我不知道如何从路径读取文件txt并将文件中的用户和电子邮件更改为值以使其成为
$userFile = "Mike"; // user in txt file (account.txt)
$emailFile = "mike@gmail.com"; // email in txt file (account.txt)
这是我的spcial脚本，它在（account.txt）
中输出<?php
if (isset($_POST["g-recaptcha-response"])) {
$name = $_POST['name'];
$user = $_POST['user'];
$pass = $_POST['pass'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$country = $_POST['country'];
$plan = $_POST['plan'];
$quantity = $_POST['quantity'];
$payment = $_POST['payment'];
$reciever = $_POST['reciever'];
$captcha = $_POST['g-recaptcha-response'];
$message_user = $_POST['message'];
$serverip = $_POST['REMOTE_ADDR'];
$to = 'sup.alphas@gmail.com';
$parts = explode("@", $email);
$sufemail = $parts[0];
// $sufemail = substr(strstr($email, '@'), 1); for domain//
$subject_form = 'Request new account by '.$sufemail.'';
// Check if name has been entered
if (!$_POST['name']) {
$errName = 'Please enter your name';
}
// Check if name has been entered
if (!$_POST['user']) {
$errUser = 'Please enter your username';
}
// Check if name has been entered
if (!$_POST['pass']) {
$errPass = 'Please enter your password';
}
// Check if email has been entered and is valid
if (!$_POST['email']) {
$errEmail = 'Please enter a valid email address';
}
if (!$_POST['country']) {
$errCountry = 'Please enter your country';
}
if (!$_POST['plan']) {
$errPlan = 'Please enter your plan';
}
if (!$_POST['quantity']) {
$errQuantity = 'Please enter your quantity';
}
if (!$_POST['payment']) {
$errPayment = 'Please enter your method of payment';
}
if (!$_POST['g-recaptcha-response']) {
$errCaptcha = 'Please enter captcha';
}
// If there are no errors, send the email
if (!$errName && !$errUser && !$errPass && !$errEmail && !$errCountry && !$errPlan && !$errQuantity && !$errPayment && !$errCaptcha) {
// Start Create new account //
$dateadd = date('Y-m-d', strtotime("$plan"));
$datetry = date('Y-m-d H', strtotime("+1 day"));
$handle = fopen('/usr/www/users/alphacz/alpha/phpm/account.cfg', 'a');
fwrite($handle, 'F: ' . $_POST["user"] . ' ' . $_POST["pass"] . ' { expire=' . $datetry . '; afexpire=' . $dateadd . '; email=' . $email . '; Country=' . $country . '; visit_from=none; ip=none; hosted=' . $_POST['REMOTE_ADDR'] . " }\r\n");
fclose($handle);
请帮帮我
谢谢

您可以在大海捞针检查您的帐户文件。 用户名模式是＆＃34; F：{user}通过{...＆＃34; 电子邮件模式是＆＃34 ;;电子邮件= {电子邮件};国家=＆＃34; 注意：您还必须认为此抽样检查关键字不敏感，所以 在搜索和插入时，您应该将关键字转换为小写
$user_used = userExists('Mike');
$email_used = emailExists('mike@gmail.com');
if ($user_used && $email_used)
{
echo 'The user and email is used';
}
elseif ($user_used) {
echo 'The user is used';
}
else
{
//do special code
}
function userExists($user)
{
return (exec('grep ' . escapeshellarg('F: ' . $user . ' ') . ' {file-path}'));
}
function emailExists($email)
{
return (exec('grep ' . escapeshellarg('; email=' . $email . ';') . ' {file-path}'));
}

我们可以修改您当前的代码以从文件中读取，但我们首先重写您写入文件的代码，因此之后将更容易从文件中读取。
（因为你只显示写入文件的部分脚本，我只能重写那部分。）

文件的JSON格式
我们不会以自定义格式将数据写入文件，而是将数据保存在JSON format中。您可以轻松地在PHP中使用JSON，因为它有built-in functions可以使用它。
$_POST↔$_SERVER？
在某些时候你使用$_POST['REMOTE_ADDR']，但我认为你想使用$_SERVER["REMOTE_ADDR"]。请参阅：http://php.net/manual/en/reserved.variables.server.php。
!$XY
虽然使用!$XY作为条件可能有效，但它不是很实用。因为它只是否定了值，然后检查它是否是真值或假值，并且应该输入if语句。因此，我建议您使用!empty()检查您的输入是否已设置且不为空。
<强>代码
<?php
if (isset($_POST["g-recaptcha-response"])){
$checkPostIndices = ["name", "user", "pass", "email", "phone", "country", "plan", "quantity", "payment", "reciever", "g-recaptcha-response", "message"];
$data = [];
$errors = [];
$errorMessages = [
"name" => "Please enter your name",
"user" => "Please enter your username",
"pass" => "Please enter your password",
"email" => "Please enter a valid email address",
"phone" => "Please enter your phone number",
"country" => "Please enter your country",
"plan" => "Please enter your plan",
"quantity" => "Please enter your quantity",
"payment" => "Please enter your method of payment",
"reciever" => "Please eneter a reciever",
"g-recaptcha-response" => "Please enter captcha",
"message" => "Please enter a message",
];
foreach($checkPostIndices as $index){
if(!empty($_POST[$index])){
$data[$index] = $_POST[$index];
} else {
$errors[] = $errorMessages[$index];
}
}
$data["serverip"] = $_SERVER["REMOTE_ADDR"];
$to = "sup.alphas@gmail.com";
$sufemail = explode("@", $data["email"])[0];
$subject_form = "Request new account by " . $sufemail;
if(!empty($errors)){
$fileData = array_intersect_key($data, ["user", "pass", "email", "country", "serverip"]);
$fileData["dateadd"] = date("Y-m-d", strtotime($data["plan"]));
$fileData["datetry"] = date("Y-m-d H", strtotime("+1 day"));
$file = file_get_contents("/usr/www/users/alphacz/alpha/phpm/account.cfg");
$file = empty($file) ? [] : json_decode($file, TRUE);
$file[] = $fileData;
file_put_contents("/usr/www/users/alphacz/alpha/phpm/account.cfg", json_encode($file));
}
}
?>
所以现在你的数据应该存储在JSON中，如下所示：
[
{"key":"data"}
//...
]
然后您可以轻松使用json_decode()将文件解码为数组，遍历数组并检查电子邮件和用户是否已被使用。
<强>代码
<?php
$user = "Mike";
$email = "mike@gmail.com";
$file = file_get_contents("/usr/www/users/alphacz/alpha/phpm/account.cfg");
$data = json_decode($file, TRUE);
foreach($data as $v){
if($v["user"] == $user && $v["email"] == $email){
echo "Email and user already used";
}
}
?>
