Sorting strings and numbers(varchar type column) in SQL query

Problem :
                  I have a problem with sorting by a string-column when i use SQL query on MySQLServer. There are both numbers, strings and mixture of both in this column and when i sort it numbers are not looks in sorting. ex. 7.5 6 14 8.5 9. I would like to sort numbers numerically and both strings and mixed alphabetically, 14 6 7.5 8.5 9.


Soluation :

Set your query in sorting by using "order by '0000000000'+rtrim(FEILDNAME)" 

Where FEILDNAME is your varchar type column name which you want to sort. This will build up a string for the numbers with leading zeros, so they will get sorted correctly.

Image download using CURL - PHP

$url = 'IMAGE PATH URL';
  //$random_no = rand(10000,99999999);  // for random number
  //$file_handler = fopen($random_no.'.jpeg', 'w');  // random number image name
$file_handler = fopen('image1.jpeg', 'w');   // static image name as image1
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_FILE, $file_handler);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_exec($curl);
curl_close($curl);
fclose($file_handler);

Using this code you can download image from server where 'IMAGE PATH URL' is the url of image. Image is generated in jpeg file extension named as image1 or you can use random generated name.

Hope its help you.

Assign Different Menu for Login user and unregistered user

Only you have to write if else condition to check that. For example in joomla site you need to assign different menus for frontend. before login users can see a normal menu but after user login they will see another menu. you can write the code in the template index file and assign different menu.

<?php  
   $user =& JFactory::getUser(); 
   if ($user->get('id') == NULL) {   
?>   
    <jdoc:include type="modules" name="nonregister_menu">   
<?php
   } 
  elseif ($user->get('id') != NULL) {  
?>
   <jdoc:include type="modules" name="loginuser_menu">    
<?php 
   }
 ?>

Find string between two strings - PHP

This is a little function to find a string between two specified pieces of strings. This could be used to find any string between two strings.

function get_string($string, $start, $end){
 $string = " ".$string;
 $pos = strpos($string,$start);
 if ($pos == 0) return "";
 $pos += strlen($start);
 $len = strpos($string,$end,$pos) - $pos;
 return substr($string,$pos,$len);
}

$fullstring = "Find string between two strings in PHP";
$parsed = get_string($fullstring, "between ", " in PHP");

echo $parsed; 

(result = two strings)

Assign an smarty variable to a PHP variable

Developer can use PHP code in smarty(.tpl file code) within a {php} block or an {include_php}.

when developer use a {php} block inside a Smarty template developer are inside the Smarty scope (object)
So when developer need to reference a Smarty method developer would use $this
so when developer assign an smarty variable to a php variable it looks something like this in smarty:

Code:

{php}    $t = $this->get_template_vars( 'foo' ); {/php}

print_r in Smarty development

{$foo|@print_r}

The @ tells smarty to pass the entire array to the modifier rather than calling the modifier for each element of the array. 

Smarty also print array like php print_r() function: {$foo|@debug_print_var}. 

Developer may also consider smarty's debug facility (which developer can enable in-template by inserting a {debug} tag).
