Why in_array doesn't work on array that was created using loop in PHP? -

why in_array not work on array create loop php ?

this below code show match found.

<?php ($i = 0; $i < 10; ++$i) {     $people[] = $i; }     if (in_array('test', $people))   {   echo "match found";   } else   {   echo "match not found";   } ?> 

and below code show match not found.

<?php $people = array("0","1","2","3","4","5","6","7","8","9"); if (in_array('test', $people))   {   echo "match found";   } else   {   echo "match not found";   } ?> 

how solve first code show match not found

you change

$people[] = $i; ---by--> $people[] = "$i"; 

then compare strings

<?php  ($i = 0; $i < 10; ++$i) {     $people[] = "$i";  }     if (in_array('test', $people))   {   echo "match found";   } else   {   echo "match not found";   } ?>
