Seems like the xTalk spirit would say something like:
set the isbuffering to true
set the isbuffering to false
put the length of the outputbuffer
replace "me" with "you" in the outputbuffer
send outputbuffer
There would be some interesting possibilities if you could just
address "the buffer" as a container and even modify it after the fact
but before sending. Technically you can do the same in PHP (fetch the
buffer into a variable, modify it, output it) but it's a bit messy in
that case.
So what would be a good way to express this via on-rev?
in PHP scripting
ECHO or PRINT do the immediate send of a string to a
browser when that line is executed...
unless you turn on Output Buffering
ob_start() -- Turn on output buffering
then later
$stringToSend = ob_get_flush()
-- Flush the output buffer, return it as a string and turn off
output buffering
or, at the end of the script execution,
the output buffer will automatically be sent to the browser .
The Output Control functions allow you to control when output is
sent from the script. This can be useful in several different
situations, especially if you need to send headers to the browser
after your script has began outputting data. The Output Control
functions only affect functions such as echo() and data between
blocks of PHP code, and do not affect headers sent using header() or
setcookie().
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(). Alternatively, ob_end_clean()
will silently discard the buffer contents.
• Output Control Functions
• flush — Flush the output buffer
• ob_clean — Clean (erase) the output buffer
• ob_end_clean — Clean (erase) the output buffer and turn off
output buffering
• ob_end_flush — Flush (send) the output buffer and turn off output
buffering
• ob_flush — Flush (send) the output buffer
• ob_get_clean — Get current buffer contents and delete current
output buffer
• ob_get_contents — Return the contents of the output buffer
• ob_get_flush — Flush the output buffer, return it as a string and
turn off output buffering
• ob_get_length — Return the length of the output buffer
• ob_get_level — Return the nesting level of the output buffering
mechanism
• ob_get_status — Get status of output buffers
• ob_gzhandler — ob_start callback function to gzip output buffer
• ob_implicit_flush — Turn implicit flush on/off
• ob_list_handlers — List all output handlers in use
• ob_start — Turn on output buffering
• output_add_rewrite_var — Add URL rewriter values
• output_reset_rewrite_vars — Reset URL rewriter values
