  • See the duplicate question/answer, but *don't use this approach* even if it can be used. Simply, only echo/write output when you *should*. – user2864740 May 01 '14 at 03:56

Do the check before the echo or if this is for a website echo the content in a <span> tag and use CSS to hide it.

Checking before the echo:

$name = "foo";
if( $name == "foo" ){
    echo $name;
}

Changing the CSS:

$name = "foo";
echo '<span class="hidey">'.$name.'</span>';
$name = "bar";
if( $name != "foo"){
    echo "<style>.hidey{ display: none;</style>";
}

For output control I can only think of Output Control Functions in the PHP documentation.

Try to look into the example of ob_get_contents.

Hope this helps.
