Re: [PHP] $$var
As per my experience so far, there is no such depth limit existing. The only limit is imposed by the system resources (like script execution time etc.) but not by PHP.

Re: [PHP] Re: Delaying $(document).ready() in jQuery until php script finish
Also, the $(document).ready() is triggered when the DOM is ready to be manipulated. I dont know why you would consider alter the behavior of this event, maybe what you want is to create yourself a custom event handler ...

Re: [PHP] Re: Delaying $(document).ready() in jQuery until php script finish
i'm not sure i understand your problem ?!? php runs on the server, delivers html code and/or javascript to the browser and only from there the jQuery will execute it's main loop and start trigger some events such as the ready event. So the php script is always finish when javascript start to execute ...

Re: [PHP] $$var
If $a = 'foo' and $$a = nothing (i.e. no value assigned to $foo) you will get an error if you tried to use this to do something else.

Re: [PHP] $GLOBALS example script on php.net
It doesn't though, it creates a copy of the $_GLOBALS super global array, removes entries that will have been set by the system (i.e. it leaves user-defined variables) and then returns the ones that are left, so in that, the user note is perfectly correct.

Re: [PHP] $$var
Hi Ashim, These are called Variable Variables. Ideally they should be avoided, as they introduce unnecessary legibility issues. This is what it does in a nutshell, it's actually quite simple: $foo = 'bar'; $bar = 'foobar'; echo $$foo;//This prints foobar What it does is, take the value of $foo (which is 'bar') and if a variable exists by that name, it will go forth and print the value of $bar; In this case foobar.

[PHP] imap_search ?
hi ! it works if there is / are emails in the box before script run (i use
cli not web based) but after it works 1 time it doesnt work again it enters
to infinite loop ,
at that line
while(!$emails) { $emails = imap_search($inbox,'ALL'); echo "email yok\n";
print_r($emails); }
imap_search($inbox,'ALL'); it doesn't try to research emails in $inbox,
doesn't it stay as connected or it's just for 1 time use :S ? should i reuse
imap_open everytime when i need to use imap_search ?
$inbox = imap_open($hostname,$usernamex,$password) or die('Cannot connect to
domain:' . imap_last_error());
function onayla()
{
global $inbox;
$emails = imap_search($inbox,'ALL');
while(!$emails) { $emails = imap_search($inbox,'ALL'); echo "email yok\n";
print_r($emails); }
echo "\nyeaah"; print_r($emails);
if($emails) {
rsort($emails);
echo "Number of email:".imap_num_msg($inbox);
foreach($emails as $email_number) {
$overview = imap_fetch_overview($inbox,$email_number,0);
if(stristr($overview[0]->subject,"Test"))
{
$message = imap_fetchbody($inbox,$email_number,1);
echo "$message\n\r";
//$link=arasi('activate:','-- The',$message); //echo "\n\r".$link;
#fwrite(fopen("deneme.txt",w),file_get_contents($link));
//imap_delete($inbox,'1:*');
//imap_expunge($inbox);
}
}
}
imap_delete($inbox,'1:*');
imap_expunge($inbox);
}
[PHP] $$var
Dear All, I was reading the php manual for session_register, and I found the following line there : - $_SESSION[$var] = $$var; Why do I need $$ there ? Can someone explain? Thank you, Ashim
