Calling a function using variable name in PHP
<?php
function show_name()
{
echo 'Rangan Roy';
}
$var = 'show_name';
$var(); // output: Rangan Roy
?>
function show_name()
{
echo 'Rangan Roy';
}
$var = 'show_name';
$var(); // output: Rangan Roy
?>
What "e" means in PHP??
<?php echo 2e0 . '<br/>'; echo 2e1 . '<br/>'; echo 2e2 . '<br/>'; echo 2e3 . '<br/>'; /* outputs: 2 20 200 2000 */ ?>
