#18063 — how to have dio on raspberry

I have a brand new install of raspian, fresh install of apache2 + php 
+rrdools
But the php script that ran well on a old version of rapian ( I had 
compiled both apache and php at that time) faile with '
-- undefined function dio_open() '
So probably php is not compiled with dio!
Is there a way to add these functionality to php without recompile?
Many tanks to all

to give some precision, dio allow direct access to tty, ..
exmple:
$DEVICE="/dev/ttyS1";
$LOCK="/var/lock/lockdev/LCK..ttyS1";

-----
$fd = dio_open($DEVICE, O_RDWR |O_NOCTTY | O_NONBLOCK );
if (! $fd ) {
    LogErrors($myErrors,"Error opening $DEVICE");ABORT("error opening 
$DEVICE ");}

$param = array( 'baud' => 9600, 'bits' => 8, 'stop'  =>1, 'parity' => 0);
if ( ! dio_tcsetattr($fd, $param) ) {
           dio_close($fd);
           ABORT("Error while dio_tcsetattr \n");
}

$rc = dio_write($fd, "\r");
sleep(1);
while ($rs != ":" ) {
    $rs = dio_read($fd, 1);
}

$rc = dio_write($fd, "E0\r");

$rs = "";
$x =0;
while ($rs != ":" ) {
    $rs = dio_read($fd, 1);
    $x++;
    if ( $x > 10000 ) { LogErrors($myErrors,"Timeout waiting 
prompt");ABORT("Timeout waiting prompt\n"); }
}

$rc = dio_write($fd, "SH\r");

Alternatively, just use fopen(), fclose(), fread(), fwrite(). Set port 
parameters with exec("stty -F [device] [parameters]"), see: man stty. 
Flushing the buffers at the right moment might be tricky, or it might 
work well automatically; I don't know.

Look at this old thing for inspiration:

Unless you find php7 dio package in the repository or in a ppa, you will 
need to compile your own php with dio support.

Well the intro does say

  Note:
  This extension has been moved to the » PECL repository and is no
  longer bundled with PHP as of PHP 5.1.0.

That might be helpful to know...

As was the more imnporatnt note:

"It is not bundled anymore. See http://pecl.php.net/dio to fetch the CVS 
version (being unmaintained, there is no release in pecl). Not a bug > 
bogus."

“it should be clear by now to everyone that activist environmentalism 
(or environmental activism) is becoming a general ideology about humans, 
about their freedom, about the relationship between the individual and 
the state, and about the manipulation of people under the guise of a 
'noble' idea. It is not an honest pursuit of 'sustainable development,' 
a matter of elementary environmental protection, or a search for 
rational mechanisms designed to achieve a healthy environment. Yet 
things do occur that make you shake your head and remind yourself that 
you live neither in Joseph Stalin’s Communist era, nor in the Orwellian 
utopia of 1984.”

I could not find it.  Maybe we are seeing different text?

Yes, that's useful, but it's in a user note.  This one is probably
reliable though.
