[RESOLVED] 2 dimensions array: problem foreach

[choubix]

hello,

I have a script where, if the user recommend the website to his friends I send them an email.
it works just fine BUT: if the "friend" is already registered on the website the email is still sent to him...

so I got this code:

	$array = array( array("$email1", "$sendmail1"),
			         array("$email2", "$sendmail2"),
			         array("$email3", "$sendmail3"),
			         array("$email4", "$sendmail4"),
			         array("$email5", "$sendmail5")
			         );

	foreach($array as $key=>$value) 
		{
		foreach($value as $subkey=>$subvalue) 
			{
			if(isset($subvalue)) 
				{
				$swift->send($message, "$value", "[e-mail]");
				}
			}
		}

what I am trying to do here:

• read the array

• $value = email address

• $subvalue = the value of sendmail (if set: value = 1)

• for each email, check the value of sendmail (called $subvalue)

• if $subvalue exists in the array, use the email in the script.

the thing is: it doesnt work...

can anybody give me a hand on this please?

thanks!

hi,

I tried to reverse the values and subvalues. still it doesnt work.
I think the problem comes from the !empty() as I try to skips the $values that are empty when sending the email.

		$array = array( array("$sendmail1", "$email1"),
						array("$sendmail2", "$email2"),
						array("$sendmail3", "$email3"),
						array("$sendmail4", "$email4"),
						array("$sendmail5", "$email5")
						);

	//while(list($key,$value) = each($email)
	foreach($array as $key=>$value) 
		{
		foreach(!empty($value) as $subkey=>$subvalue)
			{
			$swift->send($message, "$subvalue", "[e-mail]");
			}
		}

hope someone can help me there 🙂

managed to find the answer! 🙂

$array = array( 
						array("$sendmail1", "$email1"),
                        array("$sendmail2", "$email2"),
                        array("$sendmail3", "$email3"),
                        array("$sendmail4", "$email4"),
                        array("$sendmail5", "$email5")
                        );  

	     foreach($array as $key=>$value)
            {
				if(!empty($value[0]))
				{
				$swift->send($message, "$value[1]", "[e-mail]"); 
				print_r($value[1]);
				}
			}
