I cannot access my Joomla administration

I can’t access my site anymore.

This could happen for various reasons, such as:

your IP address was automatically added to the Blacklist area
you accidentally added your own country to the Country block area
you haven’t allowed your user to access any component from within the Joomla! administrator area
forgot the additional backend password

To overcome these restrictions, you will simply have to open your FTP account, head to:

/plugins/system/rsfirewall/ and rename rsfirewall.php to rsfirewall.php.bak
This will automatically disable the RSFirewall! System plugin, thus the firewall restrictions won’t be applied.

Once you have completed the above step, you will be able to access your Joomla! administrator panel as you would normally do and revert your RSFirewall! settings. After you are done, remember to rename the file back.

How to print a String in reverse order

Most to time this question is asked in Interview, how can we print a string in reverse order with for loop

//error_reporting(NULL);
$string = trim("This is a reversed string");

//find length of string including whitespace
$len =strlen($string);

//slipt sting into an array
$stringExp = str_split($string);

for ($i = $len - 1; $i >=0;$i--)
{
echo $stringExp[$i];
}

OR

you can use

<?php
echo strrev("Hello world!");

How to sort multi-dimension array according to given price

This code is very helpful for beginner in PHP. To break multi-dimension Array into one single array and then you sort it according to your need, In my scenario, I wanted to Sort it with price High to Low and Low to High so I use array_multisort().

and you can use its sorting type flags, for more details look below at code and sample code link.

					"prices" => 2.90,
                ),

        ),

);

$array = $list_box_contents;
// merging multi-dimension array into one array.
$result = array_merge_recursive($array[0],$array[1],$array[2]);
// now Sort array according to price HIGH to Low
array_multisort($result, SORT_DESC);

print_r($array);
foreach ($result as $key => $val) {
   foreach ($val as $new) {
    }
   echo  $new;
  }
