Hello to all,<br><br>I am trying to create a simple for loop, but instead of incrementing numbers, I want to increment characters. I am able to get the code to work, up until the end, when it comes time to output the last char.<br>
<br>for ($i = A; $i < Z; $i++)<br> {<br> echo "$i <br>";<br> }<br><br>In this simple example, the output would be to echo the characters A - Y, omitting Z; which is expected. If I change $i < Z to $i <= Z, one would expect to have Z included in the output. Unfortunately, this does not happen. Instead, it continues to loop past Z until it outputs YZ (A - Z, AA - AZ, BA - BZ, ..... YA - YZ). This would imply that it's matching against ZA instead of just Z. I know there are alternate ways around this, but now I'm really curious about the looping behavior here. Any insight is appreciated.<br>
<br><br clear="all">I also have a related question with an if condition, if you want further head scratching.<br><br>if ($i != M || $i != Z) { echo " | "; }<br><br>With this statement, whenever $i has the value of either M or Z it should execute the condition, but it doesn't. However, if I separate the if condition into two separate conditions statements, it works as intended.<br>
<br>if ($i != M) { echo " | "; }<br><br>if ($i != Z) { echo " | "; }<br><br>I'm not sure why the || would cause a problem, but for some reason it does.<br><br>-- <br>-Rob<br><br>Ben Franklin Quote: "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety."
