Question

At a place in my PHP application, I need to echo PHP’s Global variable’s Syntactically, i.e. something of the sort
echo "$_POST['submit']";
But this ain’t working. Can anyone please shed some light on it?

The actual piece of code is:
echo "<?php if(isset($_POST['submit'])) echo 'value="'. $_POST['{$column['Field']}'] .'"'; ?>";

Answer 1

Try using nowdoc

$str = <<<'EOD'
<?php if(isset($_POST['submit'])) echo 'value="'. $_POST['{$column['Field']}'] .'"'; ?>
EOD;

This is available from PHP 5.3 and it doesn’t interpolate into string the variable value

to echo it simply do a:

echo $str;

or a

echo htmlentities($str);
