Variables only printable from foreach loop - php

Question

I want to get the variables within a foreach loop in PHP, when it is within the while loop I can print all the object data but when I echo the variables outside of the while loop it prints only a value of the variable, how do I declare the variables global and access their values anywhere?
<?php
global $answerList, $countList;
foreach( $finalAnswer as $answerID ) {
foreach ($answers as $ans => $answer_list) {
foreach ($answer_list->unique('AnswerShortID') as $answer) {
if ($answer->AnswerShortID === $answerID){
$answerList = $answer->Text;
$countList = $answer_list->count();
echo $answerList;
}
}
}
}
echo $answerList;
?>

Answer 1

You don't need the global, you are overwriting the variables each time through the loop so the variable only contains the last one. Just save to an array, then you can loop it later or implode it to display:
// you don't need to do this in the loop
$countList = $answer_list->count();
foreach ($answer_list->unique('AnswerShortID') as $answer) {
if ($answer->AnswerShortID === $answerID){
$answerList[] = $answer->Text;
}
}
echo implode(',', $answerList);
//or
foreach($answerList as $value) {
echo "<something>$value</something>other stuff";
}

Answer 2

The below will store all values in a string, which you can then echo out later. By adding a period before the equals sign you are adding new values to the end of the string with each iteration of the loop. Your code currently deletes the last value and replaces it with a new one every time you complete the loop.
<?php
global $answerList, $countList;
foreach( $finalAnswer as $answerID ) {
foreach ($answers as $ans => $answer_list) {
foreach ($answer_list->unique('AnswerShortID') as $answer) {
if ($answer->AnswerShortID === $answerID){
$answerList .= $answer->Text;
$countList .= $answer_list->count();
echo $answerList;
}
}
}
}
echo $answerList;
?>
