PHP - Filtering A Street Address

First off, i have made a validation class using array_diff() to check if there are invalid characters submitted by a user.
Some extracts:
Code: [Select]
$this->chr_alpha_lower=array('a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z');
$this->chr_alpha_upper=array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z');
$this->chr_numeric=array('0','1','2','3','4','5','6','7','8','9');
$this->chr_symbol=array(' ','!','@','#','$','%','&','(',')','[',']','.',',',':',';','\'','"','/','=','\\','-','_','?');

...

// lets say only alpha and numeric characters are allowed
$allowed_characters=array();
$allowed_characters=array_merge($allowed_characters,$this->chr_alpha_lower,$this->chr_alpha_upper);
$allowed_characters=array_merge($allowed_characters,$this->chr_numeric);

$input_split=str_split($this->input);
$invalid=array_diff($input_split,$allowed_characters);

if(empty($invalid)){
return true;
}
return false;

I have two questions.
First, for acsii characters is this method 'full proof' or is there a way for someone to get around this validation script?

Second, a new site im developing is going to be built with UTF-8 in mind so people can use the site in their own language. How do i validate UTF-8 user input? I know about mb_strings and sanitizing UTF-8 input using this:
Code: [Select]
preg_match_all('/([\x09\x0a\x0d\x20-\x7e]'. // ASCII characters
 '|[\xc2-\xdf][\x80-\xbf]'. // 2-byte (except overly longs)
 '|\xe0[\xa0-\xbf][\x80-\xbf]'. // 3 byte (except overly longs)
 '|[\xe1-\xec\xee\xef][\x80-\xbf]{2}'. // 3 byte (except overly longs)
 '|\xed[\x80-\x9f][\x80-\xbf])+/', // 3 byte (except UTF-16 surrogates)
 $input, $clean_pieces );

$clean_output = join('?', $clean_pieces[0] );

But how do i know what to filter?

Example:
a field for the user to input first name
English: only alpha characters
Other language: ?????

Help much appreciated.

Hi there

I have the following array .

Code: [Select]
$products = array(   array( Code => "CF1",
                         Items => "Sand Tray",
                         Cat  => 'Tray',
                         ),
                  array( Code => "CF2",
                         Items => "Mobile Computer Table",
                         Cat  => 'Table',
                         ),
                  array( Code => "CF3",
                         Items => "General Service Trolley",
                         Cat  => 'Trolley',
                         ),
                  array( Code => "CF4",
                         Items => "TV Trolley",
                         Cat  => 'Trolley',
                         ),
                  array( Code => "CF5",
                         Items => "Overhead Projector Trolley",
                         Cat  => 'Trolley',
                         ),
                    array( Code => "CF6",
                         Items => "Book Trolley",
                         Cat  => 'Tolley',
                         ),
                         array( Code => "CF7",
                         Items => "Stacking Chairs",
                         Cat  => 'Chairs',
                         ),     
  ); 
What I want to do is select each by 'Cat'. For example I simply want to display all the trolleys. 

I was wondering how I do this? What functions would I use in PHP? 

Thanks a million

hi,

i am trying to filter my gps history points.

i would like to ignore points if they are too close to the previous position.

i can do this like so.

$old_lat = $old_long = "0";

                 foreach($history['data'] as $record) {

//calculate distance in meters
$distance = distance($record['latitude'], $record['longitude'], $old_lat, $old_long, "V");

if($distance >= 300) {
echo 'add(jQuery(this), number += 1, "' . date("d-m-Y @ h:i:s",$record['timestamp']) . '", "map_post.php?n=' . $name . 'u=' . $history['user'] . '", "' . $history['user'] . '", "' . $record['latitude'] . '", "' . $record['longitude'] . '");';
                
$old_lat = $record['latitude'];
$old_long = $record['longitude'];
}

the problem with the above is that if i arrive home at 6pm on friday and stay outside my house for 24hours, it will show the latest position as at 6pm on fri.

i would like it to show the 6pm friday position but with a date 'from and to' time like (28/10/11 18:00 - 29/10/11 18:00) rarther than just (28/10/11 18:00) which looks inacurate.

Possible?

I want to create a feature as you see nn this image, where it says 'filter your results' if a user clicks 'Detached Houses' then only detached houses will be displayed. if a user clicks 'Semi-detached' then only semi detached houses will be shown.
Any help is really appreciated, thank you.
Code: [Select]

<table border="0" cellpadding="0" cellspacing="0">
<tr>
<td><div id="filter"><p class="houses" style="font-family:helvetica;color:#0155a1;font-size:14px;background:url(cutouts/forsale/filter.jpg) no-repeat;"><b><u>Houses</u></b>
<br />
<span class="dh"><b><u>Detached Houses</u></b></span><?php
// Make a MySQL Connection
mysql_connect("localhost", "admin", "1admin") or die(mysql_error());
mysql_select_db("test") or die(mysql_error());

// Get a specific result from the "example" table
$result = mysql_query("SELECT * FROM example
 WHERE name='Sandy Smith'") or die(mysql_error());  

// get the first (and hopefully only) entry from the result
$row = mysql_fetch_array( $result );
// Print out the contents of each row into a table 
echo $row['name']." - ".$row['age'];
?>
<br />
<span class="dh"><b><u>Semi-detached houses</u></b></span>
<br />
<span class="dh"><b><u>Terraced houses</u></b></span>
<br />
<br />
<b><u>Flats / Apartments</u></b>

Hi guys

I was wondering if anyone could point me in the right direction with this.

I am using JSON to return the contents of a directory and then using a foreach loop to print each one to a new row in a table.

Is there anyway to filter the results? Basically I just want to show the files that end in a .jar extension? Currently all sub directories and files are shown, however all the files I need to pull will be in the main directory.

This is what I am using:

Code: [Select]
<?php
  foreach ($installedplugins1['success'] as $v) 
{
echo "<tr><td>".$v."</td>";
echo "<td><a href='index.php?dp=".$v."'>Disable Plugin</a></td>";

}
?>

Any hints or reading material?

Cheers

hey guys i was generally wondering...is it good practice to add_slashes and use mysqli_real_escape_string when entering data into the database?   then to strip slashes when extracting rows?   is this the right way to go around things...thanks    

Hello, Is it possible to allow '@' and '.' while maintaining the rest of this regex?

$email= 'adsfsa@asdf.edu';
$email= preg_replace("/[^A-Za-z0-9]/", " ", $email);
echo $email;

Hi all,

I was wondering if i can filter certain log files like using 2 keywords and get all the info inbetween? The log files are like <1 MB.

The other problem i encounter is howto since i looked all over the net but cant seem to find usefull info about it.

Can you help me out here?

I'm pretty sure the problem is starring me in the face, but I can't seem to locate it.


function filter($string)
{
//swear words pulled from bannedwordlist.com
$f = fopen('../badwords.txt', 'r');
$bad_words = fread($f, filesize('../badwords.txt'));
$bad_words = explode('\n', $bad_words);

$input = strtolower($string);

foreach($bad_words as $value)
{
$string = str_replace($value, '****', $input);
}

return $string;
}


UPDATED CODE

function filter($string)
{
//swear words pulled from bannedwordlist.com
$f = fopen('../badwords.txt', 'r');
$bad_words = fread($f, filesize('../badwords.txt'));
$bad_words = explode('\n', $bad_words);

$input = strtolower($string);
$string = str_replace($bad_words, '****', $input);

return $string;
}


I've already echoed out $value in the foreeach loop, and it does correctly retrieve the bad words and put them into an array. My only problem is, the returned string is still in strtolower() form, and the words aren't censored. :/

Hi all,

    I am working on a tool to pull data remotely and the data is set to xml format. I want to post items that meet a certain criteria only, essentially there are several layers/tags on the data being brought over. The sStatus is the primary item I am looking for, not only that but only if it has or equals to "Waiting". Any thoughts or suggestions greatly appreciated. Below is the basic code I have in place currently and am working on.

<code>
<?php
$soapclient = new SoapClient("https://secure.logmeinrescue.com/api/api.asmx?wsdl");


$sEmail = "dummy@dum.com";
$sPassword = "dum123";
$iNodeID = "123456";   
$eNodeRef = "NODE";   
$sAuthCode = "";

$loginparams = array (
'sEmail' => $sEmail,
'sPassword' => $sPassword);

$loginResult = $soapclient->login($loginparams);

$output = array(
'eOutput' => "XML"
);

$outputResponse = $soapclient->setOutput($output);
         

$sessionparams = array(
'iNodeID' => $iNodeID,
'eNodeRef' => $eNodeRef,
'sAuthCode' => $sAuthCode
);

//get session(s)
$sessionresult = $soapclient->getSession($sessionparams);
$session = $sessionresult->aSessions;
$sessionnodes = $session->SESSION;
$session_status = $sessionnodes[$isessionNodes]->sStatus;
   
   

print_r($sessionresult);

?>
</code>

I have a SQL statement which is difficult to use PDO on, it might not even be possible to do. So I'm filtering it like this:

$search = $_GET['search'];
$search = preg_replace("/[^A-Za-z0-9]/", " ", $search);
$search = $mysqli->real_escape_string($search);

Will this result in an acceptable level of security?

I'm using an INNER JOIN to grab some data from 2 tables depending on if another's id matches an id within the other table (obviously..  ).

Is there anyway to continue on with this join but to filter even deeper by only taking data that not only has matching some_id but also does not have a row that equals a certain value?

Something along the lines of adding "WHERE some_row != 'value'" ?

"SELECT * FROM my_firstTable INNER JOIN my_secondTable ON my_firstTable.some_id = my_secondTable.some_id ORDER BY my_firstTable.some_id"

Perhaps a slight trouble, but I can not solve it:   Match only path like: Trainings/1/test.pdf   but dont match one more directory like this: Trainings/1/4/other.pdf   Any suggestions?
