copied!<p>I'm pretty sure I know what's going on here, your function <code>metersToFeetInches</code> is <code>echo</code>ing a value rather than <code>return</code>ing it.</p> <pre><code>function metersToFeetInches() { echo 'OUTPUT'; } echo 'FIRST '.metersToFeetInches().' LAST'; // Outputs: OUTPUTFIRST LAST </code></pre> <p><code>echo metersToFeetInches()</code> is actually redundant.</p> <p>This is because the function runs before the string you built is actually output. Note that both examples you posted would have this problem. Change your function to <code>return</code> a value instead. Afterwards, any places where you have used it like so:</p> <pre><code>echo 'Something'; metersToFeetInches(); echo 'Something Else'; </code></pre> <p>You'll have to use an <code>echo</code>:</p> <pre><code>echo 'Something'; echo metersToFeetInches(); echo 'Something Else'; </code></pre> <p>Functions should pretty much always <code>return</code> a value. Lesson learned, perhaps?</p> <hr> <p>If you are really in a bind and cannot change the function, you'll have to resort to <a href="http://php.net/manual/en/book.outcontrol.php" rel="nofollow">output buffering</a>:</p> <pre><code>ob_start(); metersToFeetInches($productarea); $metersToFeetInches = ob_get_clean(); echo "<p><strong>" . __('Area:', 'honegumi') . "</strong> " . number_format($productarea) . " m² (" . $metersToFeetInches . " ft²)" . "</p>"; </code></pre> <p>...which is rather silly to have to do.</p>
