I am trying to setup my PHP site in my hosting server which is made from Codeigniter 2.2.0. Everything is fine only $end_date = $end_date ?: $start_date; this line of code generate a parse error -saying Parse error:
syntax error, unexpected ':' .
My hosting server php version is 5.2. How can I avoid this error?
In PHP, shorthand ternary operator is only available since version 5.3.

Since PHP 5.3, it is possible to leave out the middle part of the ternary operator. Expression expr1 ?: expr3 returns expr1 if expr1 evaluates to TRUE, and expr3 otherwise.
Try this
$end_date = (!empty($end_date)) ? $end_date : $start_date;
empty(). Evaluating $end_date in boolean context (as it happens when it is the first operand of the ternary conditional operator) is the same as ! empty($end_date).$end_date and ! empty($end_date) in this context.
$end_date = ' ';the !empty() check is usefulempty(' ') === FALSE. Compare the columns empty() and boolean: if($x) from the first table displayed in the "Comparisons of $x with PHP functions" page. if ($x) (or $x ? ... : ...) is the same as if (! empty($x)) for any value of $x.local and host PHP versions were differents.
This code solved in booth.
$end_date = (!empty($end_date)) ? $end_date : $start_date;
empty(). Evaluating $end_date in boolean context (as it happens when it is the first operand of the ternary conditional operator) is the same as ! empty($end_date).
