quick question

[justinh]

<?php

$colors = array("red", "blue", "green"); 
$ct = count($colors); 

for($i = 0; $i <= $ct; ++$i){

$rainbow .= $colors[$i].",";

}

echo $rainbow;

?>

 

this returns red,blue,green,,

 

I'm trying to get it to return red,blue,green,

nvm fixed it myself

 

<?php

$colors = array("red", "blue", "green"); 
$ct = count($colors); 

for($i = 0; $i <= $ct; ++$i){

if($i == $ct){
$rainbow .= $colors[$i]; 
}else{
$rainbow .= $colors[$i].",";
}


}

echo $rainbow;

?>

Better off using implode

 

$colors = array("red", "blue", "green");
echo implode(',', $colors);
