Previous Comments: ------------------------------------------------------------------------ [2002-11-15 20:44:10] manogarc@hotmail.com In this example, i´m triying to recover an indeterminate number of vars from a form with the code below. The type of vars is like this: $var1, $var2, $var3, ... but the succesion can be incomplete like this $var1, $var5, $var6, ... for ($n=0; n<=10; $n++) { if (isset(eval("\$var".$n.";")) { [...] } } and the error message is: Parse error: parse error, unexpected T_EVAL, expecting T_VARIABLE or '$' in d:\inetpub\wwwroot\administracion\val_empextdb.php on line 14 Thanks. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=20454&edit=1
