Convert text to binary

edmarriner · Apr 4, 2006

hi,

Is there any easy way in php to convert letters in to binary?
I just thought i would ask if there is any function before writing a long str_replace to replace the letters with binary code.

thanks,

hi,

thanks for repling so fast.

i had a look at that page but i cant work out how i could do this.
any ideas?

im want 2 basicly.

have a string and convert the string into binary.

<?php
$text = "some text here";
//some function to convert the text into binary
echo"$text";
?>

and it would output:

01110011 01101111 01101101 01100101 00100000 01110100 01100101 01111000 01110100 00100000 01101000 01100101 01110010 01100101

See if you can use this..

PHP:

<html>
<head>
<title>Binary</title>
</head>

<body>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<textarea name="text" rows="10" cols="45"></textarea><br>
<input type="submit" name="submit" value="Convert!">
<input type="reset" value="Clear">
</form>

<?php

function binary($str)
{
  $text_array = explode("\r\n", chunk_split($str, 1));

  for($i = 0; $i < count($text_array) - 1; $i++)
  {
    $newstring .= substr("0000".base_convert(ord($text_array[$i]), 10, 2), -8);
  }
  return $newstring;
}

if(isset($_POST['submit']))
{
  $text = trim(strip_tags(stripslashes($_POST['text'])));
  $text = chunk_split(binary($text), 8, " ");
  
  echo $text;
}
?>

</body>
</html>

It's pretty simple to write this function but it is also kinda impossible because of the many different character code tables. It's not like in the old Pascal times with the chr() function
