#20392 [Com]: HTML_Template_IT error with $ in values

ID: 20392 Comment by: olonoh@yahoo.com Reported By: olonoh@yahoo.com Status: Bogus Bug Type: PEAR related Operating System: Linux PHP Version: 4.2.2 New Comment: I'm not clear how that's expected behavior. I'm not referring to PHP's handling of strings, but of IT.php's usage of preg_replace() instead of str_replace(). I understand that this is necessary: $value = "\$1" but if I can print $value to STDOUT with the dollar sign, I don't understand why I have to escape it again before substituting it for a template variable. If the value isn't explicitly defined in my code, form input for example, I'd have to substitute all '$' for '\$' and then revert back to the original value if I wanted to use it in something other than IT.php.

Just add put a backslash before '$'. Thanks for your report. ------------------------------------------------------------------------ [2002-11-14 20:22:11] olonoh@yahoo.com I think you misunderstood the report. The $1 was the literal value (note the single quotes around the string). When IT.php processes the value it's evaluated instead of being taken literally -- I wouldn't think that'd be expected behavior. Try this modified example: <?php require_once('HTML/IT.php'); $value = 'I have $1 in my pocket'; $t = new IntegratedTemplate; $t->setTemplate('{x}', TRUE, TRUE); $t->setVariable('x', $value); print $value."\n"; $t->show(); ?> This prints: I have $1 in my pocket I have in my pocket The first time it's printed correctly, but after it's processed in IT.php it's printed incorrectly. ------------------------------------------------------------------------ [2002-11-14 20:06:07] nicos@php.net Thank you for taking the time to write to us, but this is not a bug.

It's certainly what would happen if used $whatever in a string anywhere else in PHP - I think people would just get confused if their variables suddenly disappeared. If you want to include a $ sign in the string, you need to escape it (\$). ------------------------------------------------------------------------ [2002-11-12 09:51:43] derick@php.net recategorize ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
