Echoing content sometimes takes a very long time

Question

I have a script that builds my webpage in one string ($content) and then echo it to the user.

My script looks like this:

$time1= microtime(true);
$conten

You may be able to do this better using output buffers. On a basic level, you use ob_start() to begin writing to an output buffer, and then ob_end_flush() to push it to the client. Here is what php.net has to say about ob_start():

This function will turn output buffering on. While output buffering is active no output is sent from the script (other than headers), instead the output is stored in an internal buffer. The contents of this internal buffer may be copied into a string variable using ob_get_contents(). To output what is stored in the internal buffer, use ob_end_flush().
