Question

Can someone please help me fix this code up? I am getting some weird error:
this for loop not working properly

<?php 
$languages=array('te','hi');
for($langIndex=0;$langIndex<count($languages);$langIndex++)
{
echo $languages;} 
?>

expected result:

te,hi

actual result:

Array Array

Answer 1

you have to get the array-entry for the iteration first ($languages[$langIndex]):

for($langIndex=0;$langIndex<count($languages);$langIndex++) {
  $language = $languages[$langIndex];
  echo $language;
} 

another possibility would be to use a foreach-loop:

foreach($languages as $langIndex => $language) {
  echo $language;
}
