I have been playing with php for quite long, and have many chances answering people
question in www.experts-exchange.com
But, this is a question that noone can answer yet :
When you install PHP4 in Win98 (I install both in Apache for Win and PWS, and some has
similar problem in IIS) :
file : try.php
<?
system("dir/w > c:\dir.txt");
print join("",file("c:\dir.txt");
?>
The execution of system() runs ok, but the 2'nd statement is never executed (the
browser simply hang).
But if I do :
C:>php try.php
it runs ok !!
When I do exec() or system() or variant of it, PHP always open a new window (DOS) to
perform the task, but then it failed to kill that process (or failed to return the
handler to web server itself)...
If this is a really bug, then Zend must consider this is a serious bug since many
people have asked "how to delete a file in Win/PWS - NT/IIS" simply because they can't
do unlink() and using exec() always fail ...
Oh ya, you may also notice if() statement :
if ($x=1 && $myname="alex" || $x=2) print "$x $myname";
it will print "1 1" ?? whereas in Perl (and other prog language) should print "1 alex"
...
it may cause bug if someone write :
function f1()
{if (???) return 1; else return "a";}
function f2()
{if (???) return 2; else return "b";}
function f3()
{if (???) return 3; else return "c";}
if ($x=f1() || $x=f2() || $x=f3())
print "function(s) debug value : $x";
It will do wrongly ...
