input type='image' $_POST problem while image sa submit button

When i used <input type="image' name="submit"/> as submit button and <input type="image' name="reject"/> as Reject button in a form ,i  notice that $_POST have no information about which button is clicked...
SOLUTION
Use a hidden field and set its value using javascript using a function 'onclick'.

For example:
<form>
<input type="text" name="name"/>
<input type="image' name="submit"  onclick="confirm('submit')"/>
 <input type="image' name="reject" onclick="confirm('reject')"/> 
<input type="hidden" name="suborrej">
</form>
<script type="text/javascript">
function confirm(status)
{
document.getElementById('suborrej').value=status;
}
</script>
Now you can check using php
if($_POST['suborrej']=='submit')
{
}
else
{
}

Sorting array of numbers using Insertion Sort in PHP (PHP Code)

Every repetition of insertion sort removes an element from the input data, inserting it into the correct position in the already-sorted list, until no input elements remain. The choice of which element to remove from the input is arbitrary, and can be made using almost any choice algorithm.


<?php
                           $num=array(1,9,3,7,8,2,5,6);
                         function insertionsort($num)
                       {
                            for ($i=0;$i<=count($num)-1;$i++)
                            {
                                 for($j=0;$j<$i;$j++)
                                   {
                                       if($num[$j]>$num[$i])
                                      {
                                       $temp=$num[$i];
                                       $num[$i]=$num[$j];
                                        $num[$j]=$temp;
                                       }
                                 }
                                //var_dump($num);
                            }
                            return $num;
                       }
                        var_dump($num);
                        var_dump(insertionsort($num));

Sorting numbers using bubble sort technique in php ( Sorting Code)

 

Bubble sort

A bubble sort, a sorting algorithm that continuously steps through a list, swapping items until they appear in the correct order.

Main article: Bubble sort

Bubble sort is a simple sorting algorithm. The algorithm starts at the beginning of the data set. It compares the first two elements, and if the first is greater than the second, it swaps them. It continues doing this for each pair of adjacent elements to the end of the data set. It then starts again with the first two elements, repeating until no swaps have occurred on the last pass. This algorithm's average and worst case performance is O(n²), so it is rarely used to sort large, unordered, data sets. Bubble sort can be used to sort a small number of items (where its inefficiency is not a high penalty). Bubble sort may also be efficiently used on a list that is already sorted except for a very small number of elements. For example, if only one element is not in order, bubble sort will take only 2n time. If two elements are not in order, bubble sort will take only at most 3n time...
<?php
$num=array(1,9,3,7,8,2,5,6);
function sorter($num)
{
    for ($i=0;$i<=count($num)-1;$i++)
{
    if($num[$i]>$num[$i+1])
    {
        //echo $num[$i].':'.$num[$i+1].'<br>';
        $temp=$num[$i];
        $num[$i]=$num[$i+1];
        $num[$i+1]=$temp;
        $num=sorter($num);
    }
   
    }
    return $num;
}
var_dump($num);
var_dump(sorter($num));

1,121,12321,123454321 create pyramid using php

1st logic

1^2 = 1

11^2 = 121

111^2 = 12321

1111^2 = 1234321

11111^2 = 123454321

<?php

for($s=1;$s<=100000;$s=($s*10)+1) 

{

    echo $s*$s.'</br>';

}

?>

using php you can create output in this way too.


<?php

$s=1;$i=1;$j=1;$m=1;$n=1;

echo $s.'</br>';

for($s=2;$s<=5;$s++)

{

    $out=$m.$s.$n;

    echo $out.'</br>';

    $m=$m.++$i;

    $n=++$j.$n;

}
