#11954 — converting numbers to ascii values

In BASIC I would run a for loop to print out the corresponding characters
for a given value.

for x=65 to 90
print chr$(x)
next x

would give ABCDEF......

how is this done in php?

for ($x = 65; $x <=90; ++$x)
  printf("%c",$x);

Ineptocracy

(in-ep-toc’-ra-cy) – a system of government where the least capable to 
lead are elected by the least capable of producing, and where the 
members of society least likely to sustain themselves or succeed, are 
rewarded with goods and services paid for by the confiscated wealth of a 
diminishing number of producers.

Nope. That just gets the numeric values of $x, not the ASCII (or other
characterset) equivalent.

  ~ $ echo '<?php for ($x = 65; $x < 91; $x++) echo($x); echo PHP_EOL ?>' |
      php
  6566676869707172737475767778798081828384858687888990
  ~ $ 

The alternative I suggested gives

  ~ $ echo '<?php for ($x = 65; $x <= 90; ++$x) printf("%c",$x);
      echo PHP_EOL ?>' | php
  ABCDEFGHIJKLMNOPQRSTUVWXYZ
  ~ $

There is a probably more efficient alternative to this shell-script/C like 
way in PHP:

  for ($i = 65; $i <= 90; ++$i)
  {
    echo chr($i);
  }

And finally:

$ php -r 'var_dump(implode("", array_map("chr", array_keys(array_fill(65, 
26, true)))));'
string(26) "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

That was a quick hack; this is better:

$ php -r 'var_dump(implode("", array_map("chr", range(65, 90))));'
string(26) "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

Note how PHP's range() differs from, e.g., Python's: <http://php.net/range>

thanks that was what I was looking for.
In my array the key is one letter.
"A"=>array()
"B"=>array()
"C"=>array()

I need to step through each character to get the list.
What is a good way to do that?

BASIC style

x=65
while x<91
a$=chr$(x)
print a$
x=x+1
wend

for-loop works fine, you can also use foreach-loop if you have a list of 
keys stored in a variable.

You don't understand. RtS isn't asking for someone to tell him how to write it -- he's asking for 
someone to write it for him.

Doug,

J.O. understands Richard quite well.  But for others reading the 
newsgroup, J.O.'s update can be helpful.

And I see Richard has his usual (lack of) intelligent response to you.

Thanks for replying for me, you are spot on as usually.

What about trying to copy this to PHP:

$x=65;
while ($x<91) {
   a$=chr($x);
   print $a;
   $x=$x+1;
}



RTFM:
http://us2.php.net/while

o, BTW, i left (at least) 1 error in above code,
maybe you can find it ???

Using a combination of the following:

http://php.net/manual/en/control-structures.for.php
http://us3.php.net/chr
http://us3.php.net/print

Or in other words, just about the same way it is in basic, but using the 
equivalent php control structures and functions instead.
