preg_replace

I am putting a site together for my own reference, to take notes on php code, so I can go back later on and see how it is done. I am storing the code in MySQL.

Obviously when I insert my code in to the database and pull this back out nothing is displayed.

For instance in this forum their is a small php tag you can use to enclose your php code before submitting. How does this work so when it displayed it looks like this below.

<? echo "For example I enclosed this in the PHP tags before submitting to the database"; ?>

hi.
<?php
is the correct way to open php code,
unless you would like possibly later get problems with your scripts

To your question.
Use this function [man]highlight_string[/man]

There is also one highlight_file() function
that can take any php page file and display it as colored code.
Try this

<?php

$php_str = '<?php echo "For example I enclosed this in the PHP tags before submitting to the database"; ?>';

highlight_string( $php_str ); // will echo directly
echo '<br><hr>';
echo '<br><br>';

// will put the highlighted colored html source in a variable
// for later display
$html_output_code = highlight_string( $php_str, true );

echo $html_output_code;
echo '<br>';
// we can show the HTML source coode of this
echo htmlentities( $html_output_code );

?>

Brilliant thank you very much.

And the <?php has now been noted. Why should we do this? is this to do with php.ini file?

The "<?" and "<?=" tags only function if the short_open_tag option is enabled. For maximum portability of your scripts, it is best not to depend on this option being enabled. Many people specifically prefer not to enable it since it conflicts with the "<?xml version='1.0' ?>" declaration tag for XML documents.
