How do I echo in PHP without carriage returns?

Whenever I do an echo in PHP, I get two extra carriage returns. For example:

<?php
  echo 'abc';
?>

yields abc[cr][cr]. If I copy my script to a different server, I even get [cr]abc[cr][cr].

How do I force PHP to echo only my string 'abc' and not the carriage returns?

I have to conclude that a server setting causes PHP to precede and follow all output with an arbitrary number of carriage returns. Of course, this is an error in the config files of the web host I'm working with. It shouldn't be like this.

PHP scripts are natively placed in HTML files, and thus white space sensitive. This means any white space surrounding your tags will be visible on screen. As you would want it to be as it could be mid-paragraph!

As the other answers suggest, either clear the new line returns surrounding your tags, or you can cheat remove the ending line breaks by tricking the PHP interpreter - by leaving off the final "?>" tag.

echo by default does not have carriage return.

Unexpected empty space or lines are mostly caused by the script usage. If your process will be on a single line, then also do use a single line in script side. As for this example; `

On a different topic as a tip, even for more convenient things, you can do so by for simple if/else statements using conditional statements

Consider following example: <?php echo ($foo == "bar") ? "Foo was bar." : "Foo wasn't bar."; ?>
