Would there be anyway to merge the below queries into a single function? As it stands only the second Strpos function works. If i remove the second one then the first one will work. I need to run both as I have to check for 2 separate strings.
$check1 = QueryWhoisServer($whoisserver, $domain);
if(strpos($check1,"No match for") !== FALSE){
return "Result Example";
}
$check2 = QueryWhoisServer($whoisserver, $domain);
if(strpos($check2,"No Data Found") !== FALSE){
return "Result 2 example";
}
else {
Any help would be much appreciated.
First of all, you should keep the output of your whois query.
$response = QueryWhoisServer($whoisserver, $domain);
Then, you can run multiple searches:
if (false !== strpos($response, 'No match for')) {
// ...
} elseif (false !== strpos($response, 'No Data Found')) {
// ...
} else {
// ...
}

I'm trying to make a php script that would make a loop that would get the contents of my site/server and if the text response is for example "false" then it would do the same thing, basically will loop until the site's text response will echo "true".
This is what i tried:
$getcontents = file_get_contents("http://example.com/script.php"); // it will echo false
if (strpos($getcontents , 'false')) {
$getcontents = file_get_contents("http://example.com/script.php");
else if (strpos($getcontents , 'false')) {
$getcontents = file_get_contents("http://example.com/script.php");
}
else if (strpos($getcontents , 'true')) {
echo "finished".;
}
I'm not sure if this is the right way or even if it is possible and i apologize in advance if i did not explain myself very well. Thank you for attention!
You could use a regular while loop.
$getcontents = 'false'; //set value to allow loop to start
while(strpos($getcontents , 'false') !== false) {
$getcontents = file_get_contents("http://example.com/script.php");
}
echo "finished";
This will loop until $getcontents does not contain false.
You could also use a recursive function like this.
function check_for_false() {
$getcontents = file_get_contents("http://example.com/script.php");
if(strpos($getcontents , 'false') !== false) {
check_for_false();
} else if(strpos($getcontents , 'true') !== false) {
echo "finished";
} else {
echo "response didn't contain \"true\" or \"false\"";
}
}
This function should keep calling itself until $getcontents contains the word true, and does not contain false.
I have a text file containing
number, zero, one
number, two, three
number, four, five
in a file called data.txt
I want to search for the number and tried this but doesnt seem to work
$file = 'domain.com/data.txt';
$searchnum = 'zero';
if (stripos($file, $searchnum) == true) { echo 'number found' }
Update 1.0
i tried this as well but it doesnt seem to pull the data on the txt file
$file = "domain.com/data.txt";
$searchnum = "zero";
if(exec('grep '.escapeshellarg($searchnum).' '.$file )) {
echo "record found";
}
else {
echo "record notfound";
}
You're doing it correctly, you just need to pull the file contents.
$file = file_get_contents('./data.txt'); // you can use a full http address if your server allows it
$searchnum = 'zero';
if (stripos($file, $searchnum) !== false) { echo 'number found'; }
stripos() returns the index of the searched string, or FALSE if it is not found.
So you would do if (stripos($file, $searchnum) !== false) { echo 'number found'; }
!== is used because you need to distinguish false from 0.
I need to match two string using PHP. Here is my code:
<?php
$fistno="9937229853";
$secondno="+919937229853";
?>
Here I need the value in $fistno is present in $secondno or not. If the value in $fistno is present in $secondno it will return true. In this case 9937229853 is present in $secondno so it should return true.
Use strpos, see here.
if (strpos($mystring, $findme) === false) {
return false;
}
return true;
Be careful and use === false as the string position in the other string can be 0 which when using == will evaluate to false when it is actually true.
Use strpos
if (strpos($fistno, $secondno) !== false) {
echo 'true';
}
You need to use == not just =
$check = 'this is a string 111';
if (strpos($mystring, $findme) === false) {
echo 'perfect match';
}
else {
echo 'it did not match up';
}
= will assign the variable.
== will do a loose comparison.
=== will do a strict comparison.
I am trying to read all lines from a file and than see if a given string contains any of these lines.
My code
$mails = file('blacklist.txt');
$email = "hendrik#anonbox.net";
$fail = false;
foreach($mails as $mail) {
if(strpos($email, $mail) > 0) {
$fail = true;
}
}
if($fail) {
echo "Fail";
} else {
echo "you can use that";
}
The blacklist.txt can be found here http://pastebin.com/aJyVkcNx.
I would expect strpos return a position for at least one string in the blacklist, but it does not. I am guessing that somehow I am generating not the kind of values within the $mails as I am expecting.
EDIT this is print_r($mails) http://pastebin.com/83ZqVwHx
EDIT2 some clarification: I want to see if a domain is within an email, even if the mail contains subdomain.domain.tld. And I tried to use !== false instead of my > 0 which yielded the same result.
You need to parse the email well since you're checking the domain of the email address if its inside the blacklist. Example:
$email = "hendrik#foo.anonbox.net";
if(filter_var($email, FILTER_VALIDATE_EMAIL)) {
preg_match('/#.*?([^.]+[.]\w{3}|[^.])$/', $email, $matches);
if(!empty($matches) && isset($matches[1])) {
$domain = $matches[1];
} else {
// not good email
exit;
}
// THIS IS FOR SAMPLES SAKE, i know youre using file()
$blacklist = explode("\n", file_get_contents('http://pastebin.com/raw.php?i=aJyVkcNx'));
foreach($blacklist as $email) {
if(stripos($email, $domain) !== false) {
echo 'you are blacklisted';
exit;
}
}
}
// his/her email is ok continue
strpos returns FALSE if the string was not found.'
Simply use this :
$fail = false;
foreach($mails as $mail) {
if(strpos($email, $mail) === false) {
$fail = true;
}
}
Or even better use this:
$blacklist = file_get_contents('blacklist.txt');
$email = "hendrik#anonbox.net";
if(strpos($email, $blacklist) === false){
echo "fail";
} else {
echo "This email is not blacklisted";
}
You have found the common pitfall with the strpos function. The return value of the strpos function refers to the position at which it found the string. In this instance, if the string begins at the first character, it will return 0. Note that 0 !== false.
The correct way to use the function is:
if(strpos($email, $mail) !== false){
// the string was found, potentially at position 0
}
However, this function may not be necessary at all; if you are simply checking if $mail is the same as $email, instead of seeing if the string exists within a larger string, then just use:
if($mail == $email){
// they are the same
}
Though you might still use foreach, that’s array reduce pattern:
function check_against($carry, $mail, $blacklisted) {
return $carry ||= strpos($mail, $blacklisted) !== false;
};
var_dump(array_reduce($mails, "check_against", $email_to_check));
Hope it helps.
Yet another way to solve this. Works fine:
$blacklist = file_get_contents('blacklist.txt');
$email = "hendrik#x.ip6.li";
$domain = substr(trim($email), strpos($email, '#')+1);
if(strpos($blacklist, $domain)){
echo "Your email has been blacklisted!";
}else{
echo "You are all good to go! not blacklisted :-)";
}
Goodluck!
I'm trying to make an if statement with 2 conditions. One that checks if one variable is NOT present & does NOT matches the word "good2go" and the other that checks to make sure "body" variable is present. I'm trying to trip the error message here. Here is what I have and what I've tried, and none of it seems to work.
if (stripos($_POST['check'], 'good2go') == FALSE && $_POST['body']) {
$error = true; }
if (!$_POST['check'] == 'good2go' && $_POST['body']) {
$error = true; }
if (!stripos($_POST['check'], 'good2go') && $_POST['body']) {
$error = true; }
if ((!stripos($_POST['check'], 'good2go')) && $_POST['body']) {
$error = true; }
How do I get this to work?
here's the entire code of contact_us.php this has the validation code and the email code.
$error = false;
if (isset($_GET['action']) && ($_GET['action'] == 'send')) {
// Winnie the pooh check
//$t = tep_db_prepare_input($_POST['verify']);
if (!isset($_POST['check']) && !$_POST['check']=='good2go' && isset($_POST['body'])) {
$error = true;
} else { // Winnie the pooh Check
$name = tep_db_prepare_input($_POST['name']);
$email_address = tep_db_prepare_input($_POST['email']);
//IP recorder start
$ipaddress = $_SERVER["REMOTE_ADDR"];
$ip = "\n\nIP: " . $ipaddress;
$content = "\n\nName: ".$name."\n\nComments: ".$_POST['enquiry'];
$product = tep_db_prepare_input($_POST['product']);
if ($product) {
$product_text = "\n\nProduct Interest: ".$product; }
$content_ip = $content . $product_text. $ip;
$enquiry = tep_db_prepare_input($content_ip);
//IP recorder end
}
// BOF: Remove blank emails
// if (tep_validate_email($email_address)) {
// tep_mail(STORE_OWNER, STORE_OWNER_EMAIL_ADDRESS, EMAIL_SUBJECT, $enquiry, $name, $email_address);
// tep_redirect(tep_href_link(FILENAME_CONTACT_US, 'action=success'));
// } else {
// $error = true;
// $messageStack->add('contact', ENTRY_EMAIL_ADDRESS_CHECK_ERROR);
if (! tep_validate_email($email_address)) {
$error = true;
$messageStack->add('contact', ENTRY_EMAIL_ADDRESS_CHECK_ERROR);
}
if ($enquiry == '') {
$error = true;
$messageStack->add('contact', ENTRY_EMAIL_CONTENT_CHECK_ERROR);
}
if ($error == false) {
tep_mail(STORE_OWNER, STORE_OWNER_EMAIL_ADDRESS, EMAIL_SUBJECT, $enquiry, $name, $email_address);
tep_redirect(tep_href_link(FILENAME_CONTACT_US, 'action=success'));
// EOF: Remove blank emails
}
}
Solution to your updated problem:
if (!isset($_POST['check']) || !$_POST['check']=='good2go' || !isset($_POST['body'])) {
$error = true;
}
The reason for the pipes vs ampersands is that you want to throw an error if ANY of the fields has issue. Also, you want to check if body is NOT set vs IS set. Glad this worked out for you!
and the other that checks to make sure "body" variable is not present.
if(stripos($_POST['check'], "good2go") !== false && !isset($_POST['body'])){
//code here
}
According to PHP docs regarding the stripos function:
This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.
So you need to change the first line to:
// Doing stripos checks you MUST use === (not ==)
if (stripos($_POST['check'], 'good2go') !== FALSE && $_POST['body']) {
$error = true; }
And to check if there is no $_POST['body'] you can change the above to:
if (stripos($_POST['check'], 'good2go') !== FALSE && (!isset($_POST['body'])) {
-- Update --
According to your comment, you need $_POST['check'] to equal 'good2go', then you shouldn't be using stripos as it will check for the existence of good2go regardless if it's exactly equal, or part of a string; 'wow this hamburger is good2go'.
So I would change the conditional to:
if (((isset($_POST['body'])) && (strlen($_POST['body']) > 0)) && ((!isset($_POST['check'])) || ($_POST['check'] !== 'good2go'))) {
// Post body has a value and Post check DOES NOT equal good2go, someone is hax0rin!
}
You may want to read up on Cross-site request forgery as it seems right inline with what you are working on.
One that checks if one variable is present & matches the word "good2go"
isset($_POST['check']) AND $_POST['check'] == 'good2go'
and the other that checks to make sure "body" variable is not present.
!isset($_POST['body'])
so, just put them together
if (isset($_POST['check']) AND $_POST['check'] == 'good2go' AND !isset($_POST['body'])) {
$error = true;
}
try this:
if(!empty($_POST['check']) && $_POST['check']=='good2go' && empty($_POST['body'])) { $error=true; }
Consider using empty instead of isset if your $_POST['body'] can be present with an empty value.
No need for all those unneeded functions. What you are trying to achieve is:
if (isset($_POST['check']) && $_POST['check']=='good2go' && !isset($_POST['body']) {
// your code
}
However, As per the title of the question: Use a ternary statement. Syntax is as such
$var = <condition> ? <true> : <false>;
