Echoing ASCII code

[phpdev@dr]

I have a php page that splits a string into chars and then echoes the ASCII code for each char. I'm trying to get it print the original value => ASCII code, splitted by :,  like:

 

A => 65: B=>66: C => 67:

 

It is currently echoing: =>65 : =>66: =>67:

Any one, please?

 

Thanks,

And where is your current code?

Do you mean something like:

 

$arr = Array('A', 'B', 'C');
foreach($arr as $val)
{
     echo $val . "=>" . ord($val) . ":";
}

 

ord

chr

Well, if the input is a string, then this will work

 

<?php

function strToASCII($textStr, $sepStr=' => ', $delimStr=' : ')
{
    $strLen = strlen($textStr);
    $resultAry = array();

    for($i=0; $i<$strLen; $i++)
    {
        $resultAry[] = "{$textStr[$i]}{$sepStr}" . ord($textStr[$i]);
    }

    return implode($delimStr, $resultAry);
}

$text = "Test";
echo strToASCII($text);

//Output:
//
// T=>84 : e=>101 : s=>115 : t=>116

?>

This is what I have:

 

<?php

$string = $_post ['string']

for($i = 0; $i != strlen($string); $i++)
{

     $asciiString .= "&#".ord($string[$i]).";";

}

$asciiCode = str_replace("&", "&", $asciiString);

echo "String in ASCII:<br>";

echo $asciiString;

echo "<br>The code:<br>";

echo $asciiCode;

?>

Great! Thank you all!!!!!!!

Just a tip: It probably doesn't make much different in this particular case (as I assume these are relatively small strings), but it is slower to have the PHP parser continually compute a value in a for loop when you can define the value before hand.

 

In this line

for($i = 0; $i != strlen($string); $i++)

 

The parser must compute the length of $string on each iterration of the loop. If the string can change length on each iterration, that would be fine. but, if the string will be 'fixed' for the duration of the loop, then it is considered better form to define a variable with that length

 

$stringLength = strlen($string);
for($i = 0; $i < $stringLength ; $i++)

Or set the length of the string inside the first parameter for the for loop to make things look cleaner:

 

for($i = 0, $stringLength = strlen($string); $i < $stringLength ; $i++)

for($i = 0, $stringLength = strlen($string); $i < $stringLength ; $i++)

 

 

I like that better. I always forget about putting additional parameters within for loops like that.
