替换包含 php 的页面的文本词

Question

I'd like to replace in text [[banner]] to an ad banner.

For example:

some text...
[[banner]]
some text...

I'd like php to find in my text all [[banner]] words and include a php page in its place, so the result would be the same as if I did:

some text...
<?php include ("banner.php"); ?>
some text...

any ideas if it is possible?

Answer 1

Using preg_replace here should be viable:

$input = "some text...\n[[banner]]\nsome text...";
$output = preg_replace("/\[\[(.*?)\]\]/", "<?php include (\"$1.php\"); ?>", $input);
echo $output;

This prints:

some text...
<?php include ("banner.php"); ?>
some text...

Note that I assume that the name of the PHP script file is whatever text be contained within [[banner]] . If not, then state the logic here.
