How can I write PHP code in PHP? I want to do this, but it doesn't work:

<?php echo '<?php echo \'aoeu\'; ?>'; ?>

Hope someone can give me a hint,

Many thanks

Answer 1

<?php echo htmlentities('<?php echo \'aoeu\'; ?>'); ?>

Answer 2

If you output some complex code definitely use a template engine like smarty.. otherwise your code will look a complete mess.

I once patched the propel ORM which does output PHP code without using a template engine. It generates all the model classes based on the XML configuration files. Their code was a big mess. Don't do it.

Answer 3

Try This

<<< is Heredoc

<?php

echo <<< EOF

<?php
echo <<< EOF
EOF;
?>

EOF;

?>

Answer 4

<?php echo '&lt;?php echo \'aoeu\'; ?&gt;'; ?>

If you don't escape the '<' and '>' they will be printed as html tags.

Answer 5

You can use highlight_string or highlight_file if you use highligh_file you have to indicate php file that you want to show

<?php
highlight_string('<?php echo\'hello\' ?>');
highlight_file("D:\local\ajax_bottom.php");
?>

or you can combine both which the best solution for me:

<?php

$string=highlight_file("D:\local\hatirlaticilar\Adminn\autocomplete\gethint.php");
highlight_string("$string");
?>

or you can combine in a different way:

<?php


highlight_string(highlight_file("D:\local\hatirlaticilar\Adminn\autocomplete\gethint.php"));
?>
