If you want just the desired result te,hi from that array, use

echo  implode(',', $languages);

You call your array ($languages) every time, in your loop...

try with : 

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

or 

foreach($languages as $langue){
    echo $langue;
}

You accidentally use echo array. Try this:

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

You should use array index when addressing to elements of array

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

You're trying to print out the whole $languages array each time around the loop -- there's nothing inside the loop which actually looks at what value $langIndex has. You could either print out the string at the index you're currently looking at:

echo $languages[$langIndex];

Or you could save yourself some trouble and use a foreach loop instead:

foreach ($languages as $lang) {
    echo $lang;
}

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;
}
