PHP print vs echo

This is a big topic for anyone writing PHP so I thought I would do my own test. I ran each 3 times ignoring the first run. With this simple test it would seams that The Data follows.

PHP 5.1.6 (cli) (built: Jul 16 2008 19:52:52)

Print

$i = 0;
for($i;$i<10000000;$i++)
{
print "Hello World.\n";
}

[blog@HomeWorkstation tmp]$ time ./print.php > /dev/null

real 0m5.894s
user 0m3.095s
sys 0m2.787s
[blog@HomeWorkstation tmp]$ time ./print.php > /dev/null

real 0m5.946s
user 0m2.943s
sys 0m2.996s
[blog@HomeWorkstation tmp]$ time ./print.php > /dev/null

real 0m5.838s
user 0m3.155s
sys 0m2.666s


Echo

$i = 0;
for($i;$i<10000000;$i++)
{
echo "Hello World.\n";
}

[blog@HomeWorkstation tmp]$ time ./echo.php > /dev/null

real 0m6.387s
user 0m3.150s
sys 0m3.208s
[blog@HomeWorkstation tmp]$ time ./echo.php > /dev/null

real 0m6.038s
user 0m3.091s
sys 0m2.928s
[blog@HomeWorkstation tmp]$ time ./echo.php > /dev/null

real 0m6.466s
