显示来自PHP foreach循环的特定值

Question

I have a simple foreach loop in PHP. I want to get specific value from that loop. I can get the 1st value with the below code but is it possible to get only 2nd or 3rd value from the same loop. My code to get first value is below,

$i = 0;
$colors = array("red","green","blue","yellow"); 
foreach ($colors as $value)
{
  $i++;
  if($i==2) break;
  echo "$value <br>";
}

Answer 1

I might be wrong, but give this a try :

       foreach($colors as $value){
           $i++;
            if($i==2){
            echo $value[1].'<br>';//To get the second; $value[2] will get the third
            }
     }

Answer 2

You want to use continue and not break to loop through all the $colors . Also, although break is not going to be used, you want to echo before break if you were to use break as done with continue :

$i = 0;
$colors = array("red","green","blue","yellow"); 
foreach ($colors as $value)
{
  $i++;
  if($i==2) {
    echo $value, "<br />";
    continue;
  }
}

Why you need a loop if you want to get specific value?

$colors = array("red","green","blue","yellow"); 
echo $colors[1]; // 2nd value
echo $colors[2]; // 3rd value
