break

I've got a bit of an issue with my little program. I have a JOptionPane asking for a number, and if that number is less than 10, a loop that just continues on and on forever doing what's in it, keeping on asking for numbers. Inside that loop, I call a method, with an int as parameter. In the method, I need to (without altering any of the code in the class that calls the method) find out whether the number I entered is less than 1. If it is, I need to call on another method. That bit's done. But! The mainloop keeps rolling, so it keeps doing the other stuff in the loop. I need to stop it from

$rows = mysql_num_rows($result) ; for ($j=0 ; $j < 3 ; $j++) { for ($i=0 ; $i < 3 ; $i++) { $row = mysql_fetch_array($result) ; echo '<a href="image2.php?id='.$row['ID'].'">'."<img src='".$row['Image']."' />".'</a>' ; } echo "\r\n"; } The code displays three groups of three images. My understanding was that \r\n and \n (double quotes) should create a new line. However it is just inserting a space between the images. Is the way am callign \r\n wrong or is it am using the wrong code to isneert a new line (line break) Examples (# = one image): Without echo \r\n: ######### With echo \r\n: ### ###

How to have the break statement in PostgreSQL? I have the structure like this: for() { for() { if(somecondition) break; } } As per my understanding it should only break the inner for loop? There is no BREAK in PL/pgSQL . EXIT terminates the loop. CONTINUE continues at the next iteration of the loop. You can attach a <<label>> to loops and add it as parameter to each of these commands. Then you terminate / continue the labeled loop. Else, it concerns the inner loop. RETURN exits from the function (so not applicable in a DO statement). All of this applies to procedural elements of PL/pgSQL, not

So what I want to do is create a casperJS function which allows us to repeat a step X times, by refreshing the page first, when this step function reaches the timeout. For unreliable test due to a specific page bug/freeze at the moment and reduce the percentage of false negative. I have just a problem, I don't know how to break this loop, because I'm in IIFE scope, see following code : var echoTest = function(){ casper.echo('Hi'); }; var trueFunction = function(){ return true; }; var verifyFailedTest = function(number, trueReturn, thenFunction){ var i = 0; //outer: <------- for (; i <= number;

I believe this is a very simple question, but I can't find a simple answer to it. I have an infinite loop, e.g. while(1) , for(;;) , and I need to break from the loop on a keypress. What is the easiest way to do this? P.S.: I can't use getch , cin.ignore , or cin.get because it stops the loop. Well, what you want is asynchronous input. All of the methods provided by cin wait for enter. You will have to use system-specific functions for that, or use a library that will do it for you. What you need to do is to not only process your logic in a while loop, but also listen from message pipe from

I'm trying to break a PHP array into 3 columns (has to be columns, not rows) so it would look something like this: Item 1 Item 2 Item 3 Item 4 Item 5 Item 6 Item 7 Item 8 Item 9 Item 10................ The best approach I can think of would be to break the main array into 3 arrays, 1 for each column although I can't work out the best approach to do this - more specifically the criteria I could use to generate the 3 arrays. TroodoN-Mike I would use this: $i = 1 foreach ($array as $value) { if ($i % 3 === 0) { echo $value . '<br />'; } $i++; } Or when using html table: <table> <tr> <?php $i = 0;
