Adding Text To Image Script	View Content

View Content

Hello! I found this code from github. https://github.com/gburtini/Learning-Library-for-PHP and I want to know if its possible to add variables to it and what changes needed to be done to the whole script.
My first guess is the variables are

$xs

and

$ys

I want replace them and add two more. The whole code is he

<?php 

    require_once 'function.php';

    function ll_nn_predict($xs, $ys, $row, $k) {
        $distances = ll_nearestNeighbors($xs, $row);
        $distances = array_slice($distances, 0, $k);

        $predictions = array();
        foreach($distances as $neighbor=>$distance) {
            $predictions[$ys[$neighbor]]++;
        }
        asort($predictions);

        return $predictions;
    }

    function ll_nearestNeighbors($xs, $row) {
        $testPoint = $xs[$row];

        $distances = _ll_distances_to_point($xs, $testPoint);
        return $distances;
    }

    function _ll_distances_to_point($xs, $x) {
        $distances = array();
        foreach($xs as $index=>$xi) {
            $distances[$index] = ll_euclidean_distance($xi, $x);
        }
        asort($distances);
        array_shift($distances);
        return $distances;
    }

and the function.php that is required is this:

<?php

    function ll_transpose($rows) {
        $columns = array();
        for($i=0;$i<count($rows);$i++) {
            for($k = 0; $k<count($rows[$i]); $k++) {
                $columns[$k][$i] = $rows[$i][$k];
            }
        }
        return $columns;
    }

    function ll_mean($array) {
        return array_sum($array)/($array);
    }

    function ll_variance($array) {
        $mean = ll_mean($array);

        $sum_difference = 0;
        $n = count($array);

        for($i=0; $i<$n; $i++) {
            $sum_difference += pow(($array[$i] - $mean),2);
        }

        $variance = $sum_difference / $n;
        return $variance;
    }
 
    function ll_euclidean_distance($a, $b) {
        if(count($a) != count($b))
            return false;
        
        $distance = 0;
        for($i=0;$i<count($a);$i++) {
            $distance += pow($a[$i] - $b[$i], 2);
        }

        return sqrt($distance);
    }

I just want to know where is the variables in those 2 scripts and add more as I'm not well versed in using PHP. Thank you!

I found a newsletter script called 'easy newsletter' which allows me to set up a page for users to sign up to a news letter emailing list. There is then another page that a admin can log into and create a simple text email to send out to everyone that has signed up. My problems is i require the email to include a attachment and have no clue how i can add this to the script to get it working. Can anyone help me?

The script that sends out the email is included below if this helps:
<?php
  //load configuration
  require("config.php");

  //connect to database
  @mysql_connect($db_server,$db_user,$db_password) or die("Database server connection failed. Check variables \$db_server, \$db_user and \$db_password in config.php");

Adding Rows To Smartframes Script

Hi, I am developing a web application which will be comprised of three columns: (1) Search form, (2) Image gallery, (3) Image details. The site is going to be more like html framesets, but research reveals that framesets are not favourable due to many reasons. I however found an alternative that I want to use instead of html framesets http://www.ironspide...smartframes.htm I thought it would be easy for me to add rows which should serve as a page header, but I was wrong. I tried adding document.write('<frameset rows="17%,*" frameborder="no">'); to this part of the code, but row apeared in a wrong place at the bottom:

// Writes frameset

document.write('<frameset rows="17%,*" frameborder="no">');
document.write('<frameset cols="25%,75%" frameborder="no">');
document.write('<frame src="' + menuURL + '" name="menu">');
document.write('<frame src="' + contentURL + '" name="content" marginheight="15" marginwidth="50" scrolling="yes">');
// -->

The original script for the index.html page is as follows:

<!--
/* SmartFrames - Author: Robert Darrell - http://www.ironspider.ca/ */
// Defines variables
// REPLACE menu.htm WITH YOUR MENU PAGE
// REPLACE page1.htm WITH YOUR INITIAL CONTENT PAGE
menuURL = "menu.htm";
contentURL = "page1.htm";
reloadURL = parent.document.URL;
orphanURL = reloadURL.substring(reloadURL.indexOf('?')+1, reloadURL.indexOf('&'));
frameName = reloadURL.substring(reloadURL.indexOf('&')+1, reloadURL.length);

// Reassigns variable according to frame name passed by orphan
if (frameName == "menu") {
menuURL = orphanURL; 
} else if (frameName == "content") {
contentURL = orphanURL;
}

// Writes frameset
document.write('<frameset cols="25%,75%" frameborder="no">');
document.write('<frame src="' + menuURL + '" name="menu">');
document.write('<frame src="' + contentURL + '" name="content" marginheight="15" marginwidth="50" scrolling="yes">');
// -->
</script>

<!-- Use the noframes section to help search engines index your site -->

Hi everyone,

I have a page that i use to upload images to my website, i got a bit fed up of uploading one at a time so i decided to add multiple file fields to the form to upload multiple images at the same time.

Im having a few problems, iv read up he http://www.php.net/manual/en/features.file-upload.multiple.php and it seems all i have to do is add [] to the form names to turn them into arrays. However when i come to upload the images, i keep getting the "$error[] = "Incorrect format!...." error from the code below. I cant seem to figure out what the problem is.

Could anybody please point me in the right direction?
