<?php

$text="HALLO";

$new_text=str_replace("A","a",$text);
$new_text=str_replace("B","b",$text);
$new_text=str_replace("C","c",$text);
$new_text=str_replace("D","d",$text);
$new_text=str_replace("E","e",$text);
$new_text=str_replace("F","f",$text);
$new_text=str_replace("G","g",$text);
$new_text=str_replace("H","h",$text);
$new_text=str_replace("I","i",$text);
$new_text=str_replace("J","j",$text);
$new_text=str_replace("K","k",$text);
$new_text=str_replace("L","l",$text);
$new_text=str_replace("M","m",$text);
$new_text=str_replace("N","n",$text);
$new_text=str_replace("O","o",$text);
$new_text=str_replace("P","p",$text);
$new_text=str_replace("Q","q",$text);
$new_text=str_replace("R","r",$text);
$new_text=str_replace("S","s",$text);

$new_text=str_replace("X","x",$text);
$new_text=str_replace("Y","y",$text);
$new_text=str_replace("Z","z",$text);

echo $new_text;

?>

Normalerweise erwarte ich jetzt 'hallo', aber es kommt nur 'HALLO'. Wieder unverändert.

@Arni:
Deine Argumentstion ist manchmal etwas undurchsichtig...

[Arni]

[superman.92]

Schon. Aber sie hilft mir nicht. Prost.

[Arni]

$text=str_replace("A","a",$text);
$text=str_replace("B","b",$text);
$text=str_replace("C","c",$text);
$text=str_replace("D","W",$text);

$text=str_replace("J","Q",$text);
$text=str_replace("K","P",$text);
$text=str_replace("L","l",$text);
$text=str_replace("M","N",$text);
$text=str_replace("N","M",$text);

$text=str_replace("X","C",$text);
$text=str_replace("Y","B",$text);
$text=str_replace("Z","A",$text);

echo $text;

?>

[TobiaZ]

OKAY: Versuch á la Arni:

<?php

$text="HIII";

$text=str_replace("A","a",$text);
$text=str_replace("B","b",$text);
$text=str_replace("C","c",$text);
$text=str_replace("D","W",$text);
$text=str_replace("E","V",$text);
$text=str_replace("F","U",$text);
$text=str_replace("G","T",$text);
$text=str_replace("H","S",$text);
$text=str_replace("I","R",$text);
$text=str_replace("J","Q",$text);
$text=str_replace("K","P",$text);
$text=str_replace("L","l",$text);
$text=str_replace("M","N",$text);
$text=str_replace("N","M",$text);
$text=str_replace("O","o",$text);
$text=str_replace("P","K",$text);
$text=str_replace("Q","J",$text);
$text=str_replace("R","I",$text);
$text=str_replace("S","H",$text);
$text=str_replace("T","G",$text);
$text=str_replace("U","F",$text);
$text=str_replace("V","E",$text);
$text=str_replace("W","D",$text);
$text=str_replace("X","C",$text);
$text=str_replace("Y","B",$text);
$text=str_replace("Z","A",$text);

echo $text;

?>

Ausgabe: HIII...

[Arni]

sag mal verstehst Du das echt nicht ??

Du ersetzt doch I durch R
und dann R wieder durch I

also was soll denn da rauskommen ??



und so läuft aber auch keine Verschlüsselung, mal nebenbei

[DrNorton]

hmm ... rein vom logischen würde ich jetzt sagen "HIII" ... aber wie war das gleich mit programmieren und logik ?!
