PHP version: 5.2.8
PHP Bug Type: Performance problem
Bug description: include of same file is re-access and re-compiled each time
within same script
Description:
------------
include "foo.php" within a loop is re-accessed & re-compile before
execution each time...
php already knows that the file has been included (include_once generates
an error), but does not remember the code within...
for source code clarity, has there is no macro-processor like in C, it is
very usefull to use the include statement...
a function call is not appropriate in every case, as local variable scope
can be a problem...
if there are 20 or more variable to be accessed, code will be not clear if
they are part of function arguments,
neither the code will be clear if all variables are declared global.
so it is really an issue for me...
Reproduce code:
---------------
<?
for ($i=0;$i<10000;++$i)
{
include "foo.php";
}
?>
foo.php : hundreds of code lines
when content of foo.php is pasted inside the loop, execution time
dramasticaly shorter..
