You will want to hook up with a bitcoin node in a technique or one other to broardcast to the newtork. There are a variety of php and bitcoin open supply repos that may do that, take a look right here https://github.com/search?q=bitcoind+php&ref=cmdform
Another choice if you do not need to run the bitcoin consumer regionally is to hook up with an api to broadcast your transaction.
An instance I discovered for php connecting to blockchain.data is as follows
<?php
$guid="GUID_HERE";
$firstpassword="PASSWORD_HERE";
$secondpassword="PASSWORD_HERE";
$amounta = "10000000";
$amountb = "400000";
$addressa = "1A8JiWcwvpY7tAopUkSnGuEYHmzGYfZPiq";
$addressb = "1ExD2je6UNxL5oSu6iPUhn9Ta7UrN8bjBy";
$recipients = urlencode('{
"'.$addressa.'": '.$amounta.',
"'.$addressb.'": '.$amountb.'
}');
$json_url = "http://blockchain.data/service provider/$guid/sendmany?password=$firstpassword&second_password=$secondpassword&recipients=$recipients";
$json_data = file_get_contents($json_url);
$json_feed = json_decode($json_data);
$message = $json_feed->message;
$txid = $json_feed->tx_hash;
?>
Hope this helps
