problem while including two scripts...

Leszek

Hi.
Could you help solve the problem:

i have a file that has two includes:

//my script
<?php
include(.'/prog1.php');
include(.'/prog2.php');
?>
the thing is that prog1.php has two loops inside and prog2.php has no loops.
So prog1.php is slower than prog2.php

So prog2.php is done before prog1.php

Am I right?

And I want to make sure that prog1.php is done before prog2.php starts

Is it possible to do?
How can it be done?

Thanks
Leszek

No.
The file 'prog1.php' will be completely 'included' before the
'prog2.php' include happens.

Try it.

As everything is executed in sequel, the line thats is before another, will
first be done before the next line is executed

so we have two scripts,

--- script1.php ---
<?PHP
for($i=0;$i<10000;$i++) {
x++;
}
echo $x."\n";
for($i=0;$i<10000;$i++) {
x++;
}
echo $x."\n";
echo "script1 finished!!!\n";
?>
--- eof ---

--- script1.php ---
<?PHP
echo "script2 finished!!!\n";
?>
--- eof ---

Without any deep study we can see that script1.php takes longer time to
execute than what script2.php
We then have the main script

--- main.php ---
<?PHP
include('script1.php');
include('script2.php');
?>
--- eof ---
No matter which computer, what type of CPU it has, as long as it has a working
version of PHP that supports include(), echo() and for() (that should be all
released versions), you will get the same result

--- output of executing main.php ---
10000
20000
script1 finished!!!
script2 finished!!!
--- eof ---

If you want to execute something at the same time, you need to fork the
process and for that you need pcntl_fork()

and to make things to do as you don't want, that the results from the fastest
script run will come first, then you need to modify the main.php to look
something like this

--- forkedmain.php
if (($pid = pcntl_fork()) == -1) {
die("could not fork");
} else if ($pid) {
include('script1.php);
} else {
include('script1.php);
}
?>
--- eof ---

This could result in an output that looks more like

--- output of executing main.php ---
script2 finished!!!
10000
20000
script1 finished!!!
--- eof ---

So to be sure that your first include will be executed before your second
include, _DON'T_ use pcntl_fork().

Leszek,

Simply put, php programs are actually scripts which get interpreted from
the top down ( barring any inline methods ).

A simple example I think will illustrate your problem (or lack thereof).
The code for the 3 scripts is below.

//file test.php
<?php

include("test.inc-1.php");
include("test.inc-2.php");

echo " Done!";

?>
//file test.inc-1.php
<?php

for ($x = 0; $x < 100; $x++) {
for ($y = 0; $y < 50; $y++) {
echo '- ';
}

echo ' ';
}

?>
//file test.inc-2.php
<?php

echo ' Now in test.inc-2.php';

?>
If you run the script 'test.php' you will see that all of the output
generated from test.inc-1.php is produced before the output from
test.inc-2.php. I don't think that there is any question which script
takes longer to run.

Does this answer your question, or is there something I am missing.

Cheers,
Carl.

It will be, as Carl said.

The include statement is basically replaced with the code in the file.
This code will then execute.
The second include will only be read after the code from the first file
has all been executed.
The second include statement will then be replaced with the code from
that file etc etc.

Yes so maybe the problem is somewhere else...

here are my scripts

it worked great until i added two "for" loops in "zawiadomienie.php"

and now user who sends data gets on the screen only variables from the both
"for" loops
and the one who recives is getting email with all the form variables without
the ones from the "for" loops

I have no idea why it doesn't work properly :((

Thanks for any ideas

The rest can be unmodified.

The problem is that you are mixing storage in variables and echo out, you
shouldn't do this, store everything in variables and when finished, then echo
out the stuff.

and now user who sends data gets on the screen only variables from the both
"for" loops
This for you store everything else in $tresc1 and $tresc2

and the one who recives is getting email with all the form variables without
the ones from the "for" loops

This for you didn't store those values in $tresc1 and $tresc2

Leszek,

I think your problem is in "zawiadomienie.php". In this script, you
first begin to build the variable '$tresc1' then you stop appending to
this variable and echo the contents of your for loop to the client. You
then do the same for the variable '$tresc2'.

Try changing your for loop to continue appending to the proper variables.

//example code for _second_ loop:
$tresc2 .= "";

for ($i=1;$i<=5;$i++){
$osoba=$_POST["name"."$i"];
if (strlen($osoba)>0){
$tresc2 .= $osoba." ";
}
}
$tresc2 .= "";
// end-example.

This should address getting the complete text in the email, though I
think that at this point you will not see any of this on screen. If you
wish to see it on screen, in 'uzytkownik.php' add:

echo $tresc1 .' '. $tresc2;

anytime after including 'zawiadomienia.php'.

Hope this helps.
Carl.
