Character codes (converter script)

**TechTalk** · Jul 5, 2001 00:36

I am hoping someone can help me here. I am trying to make a script that will take an email address and convert it to all character codes (‘ etc.) I have written the small script below (please keep in mind im new to php) and you will see the problem with it by looking at it. Is there any other way to search the string and replace each letter?

The script:

Code:

<?

// Do lower case
$email=ereg_replace("a","&amp;#97;",$email);
$email=ereg_replace("b","&amp;#98;",$email);
$email=ereg_replace("c","&amp;#99;",$email);
$email=ereg_replace("d","&amp;#100;",$email);
$email=ereg_replace("e","&amp;#101;",$email);
$email=ereg_replace("f","&amp;#102;",$email);
$email=ereg_replace("g","&amp;#103;",$email);
$email=ereg_replace("h","&amp;#104;",$email);
$email=ereg_replace("i","&amp;#105;",$email);
$email=ereg_replace("j","&amp;#106;",$email);
$email=ereg_replace("k","&amp;#107;",$email);
$email=ereg_replace("l","&amp;#108;",$email);

$email=ereg_replace("L","&amp;#76;",$email);
$email=ereg_replace("M","&amp;#77;",$email);
$email=ereg_replace("N","&amp;#78;",$email);
$email=ereg_replace("O","&amp;#79;",$email);
$email=ereg_replace("P","&amp;#80;",$email);
$email=ereg_replace("Q","&amp;#81;",$email);
$email=ereg_replace("R","&amp;#82;",$email);
$email=ereg_replace("S","&amp;#83;",$email);
$email=ereg_replace("T","&amp;#84;",$email);
$email=ereg_replace("U","&amp;#85;",$email);
$email=ereg_replace("V","&amp;#86;",$email);
$email=ereg_replace("W","&amp;#87;",$email);
$email=ereg_replace("X","&amp;#88;",$email);
$email=ereg_replace("Y","&amp;#89;",$email);
$email=ereg_replace("Z","&amp;#90;",$email);

// Do Numbers
$email=ereg_replace("0","&amp;#48;",$email);
$email=ereg_replace("1","&amp;#49;",$email);
$email=ereg_replace("2","&amp;#50;",$email);
$email=ereg_replace("3","&amp;#51;",$email);

$email=ereg_replace("6","&amp;#54;",$email);
$email=ereg_replace("7","&amp;#55;",$email);
$email=ereg_replace("8","&amp;#56;",$email);
$email=ereg_replace("9","&amp;#57;",$email);

// Do Misc Chars
$email=ereg_replace("@","&amp;#64;",$email);
$email=ereg_replace("\.","&amp;#46;",$email);
$email=ereg_replace("_","&amp;#95;",$email);
$email=ereg_replace("-","&amp;#45;",$email);
$email=ereg_replace(" ","&amp;#160;",$email);
 
 
 echo $email;
 
?>

Personally i would use an array to accomplish this...

Code:

$codes=array("a"=>"&#97;", "b"=>"&#98;");
//make $string equal the "string" you want to do the replacements in..
$string="dsfndfknfd";

//now we will loop through and do all the replacements..
foreach($codes as $char=>$new){
  $string=str_replace($char, $new, $string);
}

That should work..of course you will need to add all the codes to the array!

OK here is what I have now .... The same thig is happening though. When the first "a" is replaced with "&#97;" , then the next time is searches the string it finds that a in the word "amp" and replaces it too. Then it just seems to be stuck in that loop.

I am calling it like this:

Could i be doing something wrong?

Thanks alot

Hey, arghh my code was very bad...sorry! I have written and am still testing the below...it appears to be working!

Code:

<?
$codes=array(

  }

 echo $all;

That might be a good way of going if you are being paid by lines of code

However, there is a logic error in your solution in that you are replacing characters with numerals and then later replacing those numerals with other numerals. In any case, there is a simpler way to achieve your desired result.

The function ord will return the ASCII code of a character (the ordinal value)
http://php.net/manual/en/function.ord.php

So you can iterate through a string (by treating it as an array) and pack a new string with the html code for each char. To pack it into HTML you would have to prefix each ASCII value with '&#' and suffix it with ';'.

give this a whirl:

PHP Code:


<?php

function htmlCharCode($str) { // returns string

   for ($i = 0; $i < strlen($str); $i++) {

      $encodedStr .= '&#' . ord($str[$i]) . ';';

   }

   return $encodedStr;

}



// test

$email = 'doda@foobar.com';

echo htmlCharCode($email);

?>

PHP really does have a function for every occasion!
