html entities to hex.

[hassank1]

I want to enter an arabic string in a text box. so it will be converted to something like that :

 

ex: بس

 

how can I convert the numbers above to hexadecimal and the &# to '0' ..

 

I want the result to be something like that

 

$input = "بس"
$output = "06280633"

Will the format ever change, this are a fw ways to go about this, but if "بس" might change to "76;س" or "بسبسبس" one way will be better than the other....

 

To get you started dechex() returns a hexadecimal value from a decimal so;

 

<?php
$your_number = 1576;
$hex_number = dechex($your_number);
echo $hex_number;//echos 628

ok but how can I loop the whole string,is there a regular expression or something that can extract only the number(s) and convert them using the above function .. ..

My regex isn't amazing, but this should work;

 

$subject = "بس";

$pattern = "/()([0-9]+);/";

preg_match_all($pattern, $subject, $matches);

echo $matches[1][0].'<br />';
echo $matches[1][1].'<br />';
echo $matches[2][0].'<br />';
echo $matches[2][1].'<br />';

 

I've got all the array values (that you require) printed out afterwards so that you can see what's happened. After that you can just loop through them;

 

$finalPart = NULL;
for($i=0;$i<count($matches[0]);$i++) {
$firstPart = ($matches[1][$i] == '')? 0 : '';
$secondPart = dechex($matches[2][$i]);
$finalPart .= $firstPart . $secondPart;
}
echo $finalPart;

 

So when you put it altogether;

 

<?php
$subject = "بس";
$pattern = "/()([0-9]+);/";
preg_match_all($pattern, $subject, $matches);

$finalPart = NULL;
for($i=0;$i<count($matches[0]);$i++) {
$firstPart = ($matches[1][$i] == '')? 0 : '';
$secondPart = dechex($matches[2][$i]);
$finalPart .= $firstPart . $secondPart;
}
echo $finalPart;
?>

Sorry, U've never dealt with different languages with php so that is not a question I can help you with, I'm sure someone else will take a look for you. I'd recommend starting a new thread as this want might be ignored because  of the number of posts...
