Remove empty elements from an Array using PHP
In the variable data array I have given 8 data elements.
Let $a, $b, $c, $d,$e contains data and others that is $f, $g, $h are empty so we will get the new array size as 5 by using the sizeof() function in PHP.
<?php $data=array("$a", "$b", "$c", "$d", "$e" , "$f" ,"$g" , "$h"); //print_r($data); function array_trim($data) { $j = 0; for ($i = 0; $i<count($data); $i++) { if ($data[$i] != "") { $b[$j++] = $data[$i]; } } return $b; } $new_size=array_trim($data);
good..
