handling strings

What is the best way to handle strings?

echo $variable1 . 'this is a string with a ' . $variable2;

echo "$variable1 this is a string with a $variable2";

echo $variable1 . "this is a string with a " . $variable2;

echo <<<EOF
$variable1 this is a string with a $variable2
EOF;

echo $variable1 ?> this is a string with a <?php echo $variable2; ?>

Are there speed advantages in the different situations?

Speed differences are so small that they'd be swamped by other factors. What's important is how readable the source code is and how easy it is to maintain.

Incidentally, the third and fourth examples produce different results from the other two. Is this intentional?

Nice answer. Thx.

Did the third and fourth really produce different results? They shouldn't.

<?php

$variable1 = 'foo';
$variable2 = 'bar';


echo $variable1 . 'this is a string with a ' . $variable2;

echo "\n";

echo "$variable1 this is a string with a $variable2";

echo "\n";

echo $variable1 . "this is a string with a " . $variable2;

echo "\n";

echo <<<EOF
$variable1 this is a string with a $variable2
EOF;

echo "\n";

echo $variable1 ?> this is a string with a <?php echo $variable2; ?>

foothis is a string with a bar
foo this is a string with a bar
foothis is a string with a bar
foo this is a string with a bar
foo this is a string with a bar
