Hi again,

I need a code to display numbers in a row, each time the same echo code is displayed. For example, the first time it is displayed i'd want it to display 1, then the second it would display 2, and so on. I'm trying to do something like the following code at the moment, but the problem is a can't get it to display anything other than 1 each time the echo code is posted

PHP Code:

<?php

while ( $num <= 0 ) {

    $num += 1;

}

?>



<?php echo $num; ?>

Perhaps if someone could show me a correct code? Also, the echo code has to be the same each time, so things the following code won't work, because i will be deleting certain parts of the code at certain times, and i will need it to, say, if i delete part number two, for it to display '2' on number three, if you follow what i mean...

PHP Code:

<?

$numbers=array("1","2","3");

sort($numbers);

?>



<?php echo $numbers[0]; ?>



<?php echo $numbers[1]; ?>



<?php echo $numbers[2]; ?>

Thanks to everyone who helps, if you can understand this, and also thanks to blaw, i got my code working last time

loops are something useful in PHP
try to use FOR .. that's how is can be used :

PHP Code:

$names=array('NeverMind','tsb','Ryan');

$num=count($names);



for ( $i=1; $i<$num; $i++ ) {

  $counter=$i-1

  echo"$i- $names[$counter] .";

} 

and if you want to use it when you fetch data from databases like MySQL e.g. you need to make sure that mysql_fetch_array() is inside the loop not outside it.. like this :

PHP Code:

$fetch=mysql_query("SELECT * FROM table")or

die('couldn\'t excute query: '.mysql_error());



$num=mysql_num_rows($fetch);



for ( $i=1; $i<=$num; $i++ ) {

  $data=mysql_fetch_array($fetch);

  //we put it inside loop not outside it,

  //otherwise it will print the same data through the loop

  

  echo $data['ID'], $data['name']; 

} 

BTW if you want increment of a variable by 1 , you could use $var++ ..

Is that the whole code, because when i use it, it says:

Code:

Parse error: parse error, unexpected T_ECHO in /blah/blah/blah/numbers.php on line 7

All i basically want is something like:

PHP Code:

<? 

$numbers=array("1","2","3"); 

?> 



<?php echo $numbers; ?> 



<?php echo $numbers; ?> 



<?php echo $numbers; ?>

Obviously that doesn't work, but i want it to display 1, 2, and 3 in each of the echos, in that order, with the echo codes being identical to each other...

PHP Code:

<?php 

$num = 0;

while ( $num => 0 ) { 

    $num ++; 

    echo $num; 

} 

?>

Will produce an endless loop of numbers

I used:

PHP Code:

<?php

$num = 0;

while ( $num >= 0 ) {

    $num ++;

    echo $num;

}

?>

...but how can i get it to display one number at a time, and in places i want it by using:

PHP Code:

<?php echo $num; ?>

So for example the echo in the second code would display '1', and then if i used that code again underneath it would display '2', and then if i used it again it would display '3', and so on?

Thanks

hmm you could create a function

ie

PHP Code:

<?

function add1($num){

$num++;

return $num;

}

$numb = 1;

?>

Then whenever you want to call another number you

PHP Code:

<?

$numb = add1($numb);

echo $numb;

 ?>

You can make that a bit shorter but it not that long anyway

Thanks, that's perfect =D
