<?php
$input = array(

				'email' => 'abc@test.com',
				'first_name' => 'aaa',
				'last_name'  => 'bbb',
				'website'	 => 'www.abc.com',
			),
			array(
				'email'	=> 'def@test.com',
				'first_name' => 'zzz',
				'last_name'	 => 'yyy',
				'website'	 => 'www.zzz.com',
			),
		);


$output = array_map(function($arr){
	$result = array('email' => $arr['email']);
	unset($arr['email']);
	foreach($arr as $key => $val) {
		$result['properties'][] = array('property' => $key, 'value' => $val);
	}
	return $result;
}, $input);


print_r($output);
