For this module it’s best that your development environment is configured to send live emails.
If it’s local, xampp perhaps, and not currently configured as such,
you may want to refer to this post first:
http://alexyz.com/sending-mail-xampp-gmail/
Step 1, of course, create a new folder entitled emailusers in sites/all/modules
Step 2, in that folder, create emailusers.info, containing the following
(if you’ve read Notes 1-4 this should all be very familiar already):

In your theme (wp-content/themes/YourNewTheme) create or find functions.php
and start making whatever you need. It’s a nice clean place to put things without hacking away at your code,
dynamically inserting with JS, or whatever other measure you’ve either employed in the past, or are considering now…
for example,
<?php
//My own footer hook
function my_footer() {
//code to execute
?><div class=”bigText”>blah blah blah</div><?
}
?>
then, wherever you like, call your new function, example, replace … READ MORE

$original = “foo”;
$ref = &$original;

// now we change the value of $original
$original = “bar”;
// and then print the value of the referring variable
echo $ref; \\Now prints the new value: “bar”

The fgets() function is used to read a single line from a file.
Note: After a call to this function the file pointer has moved to the next line.
The example below reads a file line by line, until the end of file is reached:
| <?php $file = fopen(“welcome.txt”, “r”) or exit(“Unable to open file!”); //Output a line of the file until the end is reached while(!feof($file)) { echo fgets($file). “<br />”; } fclose($file); ?> |
date(format,timestamp)
format is required, example:
date(“Y-m-d”)
of course, Y, m, and d stand for Year, month, day, and they may be separated by whatever you like, so the above example returns 2010-07-27, while date(“m/d/Y”) returns 07/27/2010
now for the timestamp parameter
MAKE what should be supplied for the timestamp, with mktime(hour,minute,second,month,day,year,is_dst)
$tomorrow = mktime(0,0,0,date(“m”),date(“d”)+1,date(“Y”))
date(“Y/m/d”,$tomorrow) returns tomorrow!
example from :
http://w3schools.com/php/php_looping.asp
<?php
$i=1;
do
{
$i++;
echo “The number is ” . $i . “<br />”;
}
while ($i<=5);

Key difference, it ALWAYS executes once, and THEN evaluates
variable variables create variables with variable names
$Bar = "a";
$Foo = "Bar";
$World = "Foo";
$Hello = "World";
$a = "Hello";
$a; //Returns Hello
$$a; //Returns World
$$$a; //Returns Foo
$$$$a; //Returns Bar
$$$$$a; //Returns a
$$$$$$a; //Returns Hello
