neds75 Posted July 13, 2006 Share Posted July 13, 2006 Hi programmers,I have one problem, and don't have idea how to solve it.Here is very much simplyfied code with which I have problem:[code]<?php$variable = "<?php \$v1 = \"10\"; \$v2 = \"50\"; \$output = \$v1+\$v2; @include \"./functions.php\";//This function provde some output too echo \$output; ?>";$template = "<html> <head><title>Test</title></head> <body> <%variable%> </body> </html>";$template = str_replace("<%variable%>",$variable,$template);echo $template;?>[/code]The problem is when I run this script in browser I get next html code:[code]<html> <head><title>Test</title></head> <body> <?php $v1 = "10"; $v2 = "50"; $output = $v1+$v2; @include "./functions.php"; echo $output; ?> </body> </html>[/code]Of course this is totaly expected($variable is string), but I want that all php variables to be substituted with their values when I do echo $template, so I do not want any php code in browser.I solved this problem by writing $template to file, and then called this file via class that imitate browser(snoopy), and it works as I wanted, but the problem is because I have to write to file, and that may be very slow(this is part of template engine).SO my question is:Is it possible to do substitutions somehow in memory, without writing template variable(or $variable) to file and accessing it via browser?I know this is very specific problem, hope someone will have some ideas.

GingerRobot Posted July 13, 2006 Share Posted July 13, 2006 Perhaps i am missing the point here with your simplified version, but couldn't you just put the php information that you want that is currently in $variable and put it in a file and include the file?

neds75 Posted July 13, 2006 Author Share Posted July 13, 2006 That script is part of bigger system, and I have to do it thatway.ANyway, I found sollution(got it on another forum), and that is eval() function.Thanks,Ivica Link to comment https://forums.phpfreaks.com/topic/14460-variable-substitution-problem/#findComment-57225 Share on other sites More sharing options...
