eval does not work reliably in conjunction with global, at least not in the cygwin port version. So: <?PHP class foo { //my class... } function load_module($module) { eval("global \$".$module."_var;"); eval("\$".$module."_var=&new foo();"); //various stuff ... ... } load_module("foo"); ?> becomes to working: <?PHP class foo { //my class... } function load_module($module) { eval('$GLOBALS["'.$module.'_var"]=&new foo();'); //various stuff ... ... } load_module("foo"); ?> Note in the 2nd example, you _always_ need to use $GLOBALS[$module] to access the variable! ---- Server IP: 212.124.37.9 Probable Submitter: 62.216.215.89 ---- Manual Page -- http://www.php.net/manual/en/function.eval.php Edit -- https://master.php.net/note/edit/84140 Del: integrated -- https://master.php.net/note/delete/84140/integrated Del: useless -- https://master.php.net/note/delete/84140/useless Del: bad code -- https://master.php.net/note/delete/84140/bad+code Del: spam -- https://master.php.net/note/delete/84140/spam Del: non-english -- https://master.php.net/note/delete/84140/non-english Del: in docs -- https://master.php.net/note/delete/84140/in+docs Del: other reasons-- https://master.php.net/note/delete/84140 Reject -- https://master.php.net/note/reject/84140 Search -- https://master.php.net/manage/user-notes.php
