PHP - Database Checking

Hello,

I am trying to get this backlink checker that checks to make sure another website has my link on their website, so far I can check to make sure the "href" link is there and is correct, but I cant get the textContent to prove valid or not it seems to always be proving true even when the textConent is not in the mysql database.

The other persons website will have this:
<a href="http://businessinvestingsorce.com">Business Investing Source</a>

I need to make sure Business Investing Source (the textContent) matches the anchor in the database.

Here is my code:

Code: [Select]
<?php

function CheckForAnchorMatch($anchortext) {    

$query = mysql_query("SELECT * FROM allowed_anchor WHERE anchor='$anchortext'");
if(mysql_num_rows($query) != 0) {
return true;
}

return false;

} 

function CheckForTargetUrl($links, $target) {    
    foreach ($links as $link) {
        if (strpos($link, $target) !== false) {
            return true;
        }
    }

    return false;
} 
                          
function ExtractHrefLinks($html) {
    $dom = new DOMDocument;
    $linkUrls = array();
     

    @$dom->loadHTML($html);
    $links = $dom->getElementsByTagName('a');
     
    foreach ($links as $link){
        $linkUrls[] = $link->getAttribute('href');
    }
    
    return $linkUrls;
}

function ExtractAnchorText($html) {
    $dom = new DOMDocument;
    $AnchorTexts = array();
     

    @$dom->loadHTML($html);
    $links = $dom->getElementsByTagName('a');
     
    foreach ($links as $link){
        $AnchorTexts[] = $link->textContent;
    }
    return $AnchorTexts;
}

function backlink_check($contenturl){

$url = 'businessinvestingsource.com';
$source = $contenturl;

$falseFound = false;

    $html = file_get_contents ( $source );
    $links = ExtractHrefLinks($html);
 
    if (CheckForTargetUrl($links, $url) === false) {
        $falseFound = "true";
        $reportArray[$source] = 0;
    } else {
        $falseFound = "false";
    }


    $html = file_get_contents ( $source );
    $anchortext = ExtractAnchorText($html);
    
    if (CheckForAnchorMatch($anchortext) === false) {
        $falseFound = true;
    } else {
        $falseFound = false;
    }

return $falseFound;
}
?>
Help greatly appreciated

Is there an alert method for the MySQL database or something similar?   What is the proper way to check if the MySQL database connection is working?   I mean other than "creating" and "retrieving" with "insert" and "select".

I need to query a database for a starting time for a meeting, and if the start time is at 7pm, I need to allow access to a page from 6pm til 11pm.  Not a problem.

The problem lies when the ending time (4 hours after the start time) crosses over to a new day.

Here's what I have:

Code: [Select]
<?php
elseif ($row['meeting'] == "7:00pm") { $starthour = 18; $endhour = 23; }
elseif ($row['meeting'] == "8:00pm") { $starthour = 19; $endhour = 0; }

if ($thishour <= $endhour && $thishour >= $starthour)
{  include "meeting_ok.php"; }
else { echo "Meeting room is unavailable at this time...."; }
?>


The "0" for endhour is throwing things off.  How should I best account for a new day?

Thanks!

Scenario:
each row contains an ID, title, description, price, and up to 5 images. There are not always 5 images stored in each row. The images are stored as a file path which is then pulled out of the DB and used to display an image via HTML.

I need to do some sort of loop/check that looks at the contents of a particular row (actually all rows in this particular table) and then decide how many times to loop through the images to display them all correctly on the webpage.

I could statically set a variable for each column but then it would have a space for an image but nothing would show. I really want this to be able to only load the images that are stored in the DB.

Any help on how I can go about this?
thanks

Hey

In my spare time, I am working on my PHP framework.
Now, to help with development and quickly discover where I miss a type cast, I have adopted to check all parameters that are passed to a method using a function.

For instance:

            public function __construct(&$target = null, $depth = 1){
            $this->validateArguments(
                array(1 => 'int'),
                array(1 => $depth)
            );



And the code that triggers the exception:
        public function testPhpFreakType(){
            $obj = 1;
            $p = new Xcms_DataStructures_Pointer($obj, "1");
        }


Code: [Select]

I think this speeds up my development quite a bit, because I can catch errors very early in the development process.
I can give multipe possibilities of what is allowed for each parameter, not just a single possibility. Also, it is possible to register custom type/validity-checks on both global and local scope.

One thing I do worry about, however, is the the performance. Of course, I could just make the funciton do nothing in production code, if it takes too much time, or I could write a script to remove all calls to that function.

When I started learning python a while back, the concept to just code to interfaces instead of types seemed very intuitive and made my code much more flexible. Of course that is what I do with PHP as well, but I it's not entirely the same. So now, coming back at my PHP code and having introduced features of static languages such as type checking, I worry about whether that is the right approach.

What are your thoughts on the matter?

I have written the code for email check, but how and where can I put the code to check if a username has been used twice? Thanks in advance.

Hello all, it's been a while! Good to be back.

I am having trouble with a script I'm trying to modify to seach for domains with specific extensions.

Now, I have never done any domain checking before and I'm a little bewildered.

The script uses an array and checks the input against each extension using the array.
Each line looks similar to:
Code: [Select]
'.com' => array('whois.crsnic.net','No match for'),

What does the whois.crsnic.net mean? I assume it's a register/database of domains?

$characterIDs = explode(',', $_POST['characterIDList']);

After the explode I want to take all those values and do a select statement in a database table for any of the values that match any of the values inside that variable variable. Not sure how to do this since there is no limit to how may there could be.

Hello!

Does anyone know an effective way to track inactive idlers in daily basis?
So that it will count the amount of days no data has been posted to the table. 

E.g.

User posts latest data and inserts timestamp 1282228120 which reads Thursday, August 19th 2010, 14:28:40 (GMT)
The days for inactivity should output as 8 days because no data has been posted from 20th August to today - 28th August.

Anyway I can achieve this?
Any information is appreciated, thanks.

So basically I have a site, and on that site, I have a page that submits a form and updates a database. I have it set up so that someone can enter in Multiple values into a textarea, one on each line, and it will submit each of those values as a new row in the database, but for the life of me, I cannot figure out how to check those values against the actual users.

It is basically a point system, where the staff can award points users of the site. But at the moment, a Staff member could enter in Jibberish, and it would insert that into the database, but I want it to check my users table to make sure the user exists before it inserts it into the database.

here is my code:
<?php
include 'global.php';

echo $headersidebar;


if ($_COOKIE['access'] == $accessstaff)
{





if(count($_POST))
{



$array = preg_split('/(\r?\n)+/', $_POST['studentname']);
foreach($array as $students)
   {
   
   $statusmsg = '<center><span style="background: #A6FF9E;">You have successfully submitted points to the database.</span></center>';
   
   mysql_query("INSERT INTO points (giver, receiver, points, category, reason, date, status) VALUES ('{$_COOKIE['username']}', '{$students}', '{$_POST['pointamt']}', '{$_POST['pointcat']}', '{$_POST['pointreason']}', '{$date}', 'Validating')");

I am fairly new to PHP, so I would appreciate any help someone could give me; I am not too good with arrays and such, so this one has got me stumped.

I don't know precisely how to put it so i will give an example:

suppose you have a search form with input fields for:

-an age range,
-a data range,
-for the sex,
-postal code

as soon as the user would fill in one of these input fields, a query should be generated including a condition doing something with the inputted value.

For example, the user fills in maxAge, the the query should say: SELECT * FROM table WHERE age >= maxAge;

Filling more than one criterion then would do .= " AND criteria (condition) inputvalue " etc...

My question comes to the part about: how to check if there is already a WHERE in the clause and how to put WHERE or AND for every criterion.

Since doing like above, i won't be able to search for another criterion if i don't select maxAge first because then there would be no WHERE in the sql clause.

Hopefully i've put it clear
thanks in advance

I have textfield for signature in my form, I m checking if the signature was sent ( if(!empty($_POST['signature']))   
and if it's not empty I m putting it into the db.

The problem is that, I have noticed a greek user has entered something in greek letters, and function could not deal with it and saved it as it is.( DB field supports greek charset )

I just want to allow english and german chars with special chars ( ",',< etc. ) , no other charset like greek.
How can I do that? any function for this purpose ?

Hi friends
I have following code

Code: [Select]
function UseOfSSL($domain_name) {
   
$site = ($domain_name);
$port = 443;

$fp = fsockopen($site,$port,$errno,$errstr,10);
if(!$fp)
{
echo "Not Installed";
}

else{
echo "Yes, it is installed";
fclose($fp);
}
}

If domain name from $domain_name has installed SSL, it will show it is installed else not installed.

Problem is that I tried this with both types of sites, those who are using SSL and those who are not and always, it says Yes, it is installed.
443 is used because https uses port 443
What is the cause ?
