note 61323 deleted from function.eval by danbrown

Note Submitter: karig at karig dot net ---- OK, here's what I've found to work for me: Let's say I have a string like this, pulled from a much larger file: $text = "<p>The following is generated by PHP:</p>\n" . '<?php $a = 6; $b = 4; $c = $a + $b; ' . 'echo "<p>Variable c = $c</p>\n"; ?>' . "<p>This is just more text.</p>\n"; Doing this just echoes the PHP code (so a visitor can actually read it by viewing the web page's source) instead of executing it: echo $text; I wanted to have the PHP code in the text executed, so that the /result/ is echoed, and the code itself is not. Happily, all I needed to do to get this to work for me was this: ob_start(); eval ('?>' . $text); $text = ob_get_clean(); // Do whatever else you want with $text before outputting it echo $text; That little '?>' prepended to $text (suggested by a previous note here) seems to be the key. Note that I DON'T append a corresponding '<?php' to $text, as a previous note suggested; I tried that, and I got an error. But I've found that "eval ('?>' . $text);" works: ---- OUTPUT ---- The following is generated by PHP: Variable c = 10 This is just more text. ---- HTML REVEALED IN WEB-PAGE SOURCE ---- <p>The following is generated by PHP:</p> <p>Variable c = 10</p> <p>This is just more text.</p>
