#48290 [NEW]: provide a function to get caller scope variables

From: kexianbin at diyism dot com Operating system: Irrelevant PHP version: 5.3.0RC2 PHP Bug Type: Feature/Change Request Bug description: provide a function to get caller scope variables Description: ------------ Provide a function to get variables from caller scope. I knew ticket 47454, 40339, 34210 are similar, but this is indeed a useful function that was overlooked. Reproduce code: --------------- Currently: $name="myname"; $value="lk,jdsk'jlkjdf"; function safe($sql) {$sql=strtr($sql, array('"'=>'\"', '\\'=>'\\\\')); return 'return "'.preg_replace(array('/\{#(.*?)\}/'), array('".addslashes($\1)."'), $sql).'";'; } $sql="insert into z_test (name, value) values ('{$name}', '{#value}')"; mysql_query(eval(safe($sql))); If we have function get_caller_vars() in caller's scope: (similar to get_defined_vars() in current scope) $name="myname"; $value="lk,jdsk'jlkjdf"; function mysql_query_safe($sql) {extract(get_caller_vars()); $sql=strtr($sql, array('"'=>'\"', '\\'=>'\\\\')); return 'return "'.preg_replace(array('/\{#(.*?)\}/'), array('".addslashes($\1)."'), $sql).'";'; $sql=eval($sql); mysql_query($sql); } $sql="insert into z_test (name, value) values ('{$name}', '{#value}')"; mysql_query_safe($sql); Expected result: ---------------- We have a function to get variables in caller scope. Actual result: -------------- No such function. -- Edit bug report at http://bugs.php.net/?id=48290&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48290&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48290&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48290&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48290&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48290&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48290&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48290&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48290&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48290&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48290&r=support Expected behavior: http://bugs.php.net/fix.php?id=48290&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48290&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48290&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48290&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48290&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48290&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48290&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48290&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48290&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48290&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48290&r=mysqlcfg
