Outputing PHP tags in a Textarea

cesarcesar

I need to show PHP and HTML code inside of a textarea for people to copy out into their own site. I can get code to work correct without PHP code in it like

htmlspecialchars("<iframe src =\"http://www.sitename.com/app/score.php?quiz_id=".$_SESSION['action']['quiz_id']."&uid=0\" width=\"480\" height=\"925\" scrolling=\"no\" frameborder=\"0\" marginheight=\"0\" marginwidth=\"0\"></iframe>".$show_commander, ENT_QUOTES);

But when adding PHP code into it its all FUBAR'd and throws a "Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /hsphere/local/home/santccom/sitename/app/step8.php on line 123 " error. This is my f'd code

<?= htmlspecialchars("<? if($_GET['proxy']){ $param = 'field_name='.$_GET[field_name].'&proxy=1'; }else{ $param = 'quiz_id='.$_SESSION[action][quiz_id].'&uid=0'; } ?>".$show_commander, ENT_QUOTES); echo'<iframe src=\"http://www.sitename.com/app/score.php?$param\" width=\"480\" height=\"925\" scrolling=\"no\" frameborder=\"0\" marginheight=\"0\" marginwidth=\"0\"></iframe>'; ?>

What i need is for something to look exactly similar to the following on screen inside of my textarea.

<? if($_GET['proxy']){ $param = "field_name=".$_GET['field_name']."&proxy=1"; }else{ $param = "quiz_id=119&uid=0"; }

echo"<iframe src=\"http://www.sitename.com/app/score.php?$param\" width=\"480\" height=\"925\" scrolling=\"no\" frameborder=\"0\" marginheight=\"0\" marginwidth=\"0\"></iframe>"; ?>

Where am i going wrong? Thanks for the help.

ok i got the result i wanted, but i thinks is very dirty. I'm going with this way for now, but im still open for suggestions on the "correct" way to do it.

<?= htmlspecialchars("<?php", ENT_QUOTES); ?> if($_GET['proxy']){ $param = 'field_name='.$_GET[field_name].'&question_num='.$_GET[question_num].'&quiz_id='.$_GET[quiz_id].'&score_id='.$_GET[score_id].'&field_value='.$_GET[field_value].'&proxy=1'; }else{ $param = '<?= htmlspecialchars('quiz_id='.$_SESSION[action][quiz_id].'&uid=0&score_id='.$_SESSION[quiz][score_id].'&offsite=1', ENT_QUOTES); ?>'; } echo"<iframe src=\"http://www.commander.com/app/score.php?$param\" width=\"480\" height=\"925\" scrolling=\"no\" frameborder=\"0\" marginheight=\"0\" marginwidth=\"0\"></iframe>"; echo"<?= htmlspecialchars($show_commander, ENT_QUOTES); ?>"; <?= htmlspecialchars("?>", ENT_QUOTES); ?>

Note: I just realized your thread title says outputting the code in a <textarea>. The following would not be good for that, but is good if you just want to display code sample, but not have them be part of a form textarea element.

A clean solution is to put the PHP text into a separate file. (If you don't want it to be executable, give it a .txt suffix or such.) Then output it with the [man]highlight_file/man function:

<h3>Example Code:</h3>
<?php
highlight_file('example_code.txt');
?>

Not only does this keep the main file cleaner, it outputs the text with context-sensitive colors.

(If it's not practical to have the PHP code in a separate file, then assign it to a variable and use the [man]highlight_string/man function, instead.)
