MySQL, phpMyAdmin and Greek

[phpfan]

Hi all,

 

I am trying to save Greek strings on my MySql database but although that the values appear correct when i retrieve them from the database when i do a "browse" in my tables the Greek values appear as strings on coded characters such as (Λαστιχα). I have try to change the Collation of the Greek fields to greek_bin and greek_latin_ci but i still have the same problem. Is there any solution??

 

I am using MySQL client version: 5.0.33 and PhpMyAdmin version 2.92

 

Thank You in Advance

It's likely you are storing them that way.  Try the following (for a post variable named "var"):

 

$var_decoded = urldecode($_POST['var']);
$var_escaped = mysql_real_escape_string($var_decoded);

 

Then put $var_escaped in the database.

 

Do you know what encoding your data is in?  UTF8?

Hi

 

I have try this and i get a result look like this ÁíôñÝáò. The variable that i try to store was Αντρέας. So the encoding has changed but not to the required... The encoding of my data is UTF-8...

 

Thank you btherl ,any further suggestions...

Oops.. it looks like php can't handle those types of entites.  And I was using the wrong function too.. Anyway, back to the problem

 

I found this function on the php website

 

   function utf8_replaceEntity($result){
       $value = (int)$result[1];
       $string = '';
      
       $len = round(pow($value,1/8));
      
       for($i=$len;$i>0;$i--){
           $part = ($value & (255>>2)) | pow(2,7);
           if ( $i == 1 ) $part |= 255<<(8-$len);
          
           $string = chr($part) . $string;
          
           $value >>= 6;
       }
      
       return $string;
   }

   function utf8_html_entity_decode($string){
       return preg_replace_callback(
           '/&#([0-9]+);/u',
           'utf8_replaceEntity',
           $string
       );
   }

 

If you feed your string into that, it will convert the data from html entities into utf8.  I tested it here, and with the sample string you gave it produces greek characters.  If you have any trouble with it let me know.

 

You should call utf8_html_entity_decode($str) to do the decoding.

Hi btherl

 

I must do something wrong because the variable that supposes to have the decode value is empty...

 

 function utf8_replaceEntity($result){
       $value = (int)$result[1];
       $string = '';
      
       $len = round(pow($value,1/8));
      
       for($i=$len;$i>0;$i--){
           $part = ($value & (255>>2)) | pow(2,7);
           if ( $i == 1 ) $part |= 255<<(8-$len);
          
           $string = chr($part) . $string;
          
           $value >>= 6;
       }
      
       return $string;
   }

   function utf8_html_entity_decode($string){
       return preg_replace_callback('/&#38;#([0-9]+);/u', 'utf8_replaceEntity',$string);
   }

$myname = utf8_html_entity_decode($name);

 

I pass the variable $name to the function which is a Greek string and then try to store the result of the decoding in the variable $myname but the variable $myname appears to be empty when i try to use it...

 

Any ideas.....  ???
