Inside a for loop, I'm trying to set a variable based on the what iteration of the loop it's on:
<?php
for ($k = 0; $k < 3; $k++){
if ($k = 0) : $var = 'zero';
elseif ($k = 1) : $var = 'one';
else : $var = 'two';
endif;
?>
This is iteration <?php echo $var; ?>.
<?php }; ?>
But it continues looping forever until my browser freezes... what's going on? Any help would be greatly appreciated!
You are essentially setting $k to be 0 and 1. Comparing values use '=='. Try this instead.
<?php
for($k = 0; $k < 3; $k++){
if ($k == 0)
$var = 'zero';
elseif ($k == 1)
$var = 'one';
else
$var = 'two';
?>
This is iteration <?php echo $var; ?>.
<?php } ?>
In the if statements, you are using the = operator which assigns...
then $k will always be 0 and the loop will never end.
Replace = to == in the if statements. So it will compare instead of assign $k a value.
A clearer example.-
if ($k = 1) // It will return 1, because you are assigning $k, 1.
But in
if ($k == 1) // It will return a boolean **true** if $k equals 1, **false** otherwise.
for ($k = 0; $k < 3; $k++){
if($k == 0){
$var = 'zero';
}elseif($k == 1){
$var = 'one';
}else{
$var = 'two';
}
}
echo $var;
