single character arithmetics?
<p>I need to invent my own conversion function because of some encoding issue.
I decided that for now I will create a conversion table for my characters.</p>

<p>I want to know how I can possibly do an operation like the following C code to print out characters 'a' to 'z':</p>

<pre><code>char a='a';
for(i=0;i&lt;26;i++){ 
  printf("%c",a);
}
</code></pre>

<p>How can I do that (incrementing characters value by value) in PHP ?</p>
