Re: PHP Syntax Question

Hi John,

Actually Zend finally did get back to me with the solution late yesterday.

In order to work with the individual elements of a data structure array from
RPG, you have to do it like this.

First, given the following PCML:

<struct name="OUT_ARRAY">
<data name="OUT_NAME1" type="char" length="30" usage="inherit" />
<data name="OUT_TICKET1" type="char" length="14" usage="inherit" />
</struct>
<program name="ATESTX1" path="/QSYS.LIB/ALIB.LIB/ATESTX1.PGM">
<data name="KSOCKCN" type="char" length="2" usage="inputoutput" />
<data name="KSOCKYR" type="char" length="2" usage="inputoutput" />
<data name="KSOCKTY" type="char" length="2" usage="inputoutput" />
<data name="KSOCKNO" type="char" length="7" usage="inputoutput" />
<data name="OUT_NAME" type="char" length="30" usage="inputoutput" />
<data name="OUT_TICKET" type="char" length="14" usage="inputoutput" />
<data name="OUT_ARRAY" type="struct" struct="OUT_ARRAY" count="5"
usage="inputoutput" />
</program>



And given that you want to access the individual elements within OUT_ARRAY,
the data structure array, you define it in PHP like this:


$out_parameters = array(
"OUT_NAME"=>"OUT_NAME",
"OUT_TICKET"=>"OUT_TICKET",
"OUT_ARRAY"=>"OUT_ARRAY");


Rather than defining it like a normal multidimensional PHP array which would
have been like this:


$out_parameters = array(
"OUT_NAME"=>"OUT_NAME",
"OUT_TICKET"=>"OUT_TICKET",
"OUT_ARRAY"=>array("OUT_NAME1"=>"OUT_NAME1",
"OUT_TICKET1"=>"OUT_TICKET1"));


Then to get to the results after the I5_Program_Call you would do this:

print "The value of Out_NAME1 is: ".$OUT_ARRAY[0]["OUT_NAME1"];
print "The value of Out_NAME1 is: ".$OUT_ARRAY[0]["OUT_TICKET1"];
print "The value of Out_NAME1 is: ".$OUT_ARRAY[1]["OUT_NAME1"];
print "The value of Out_NAME1 is: ".$OUT_ARRAY[1]["OUT_TICKET1"];

etc...


I would have never thought of that particular combination to make this work,
but work it does. Very slick actually and makes passing a large number of
records in a single I5_Program_Call really simple.

Thanks for you suggestion too!

Shannon,

The example below works - it is not as complex a situation as yours (I
always work from simple - it suits my brain!) but you should be able
to adapt. I'm also going to copy my Zend contacts on this because
there are no examples of using an array that I can find and there are
things like countref that are available in the interface that I can
find nothing about at all.

Anyway - here's the PHP:

<?php
include("conn.php");
/* connection step */
$Hdlcon = i5_connect($connect,$user, $pass,
array(I5_OPTIONS_JOBNAME=>"I5JOB"));

$description = file_get_contents("/www/zendcore/htdocs/ARRAY.pcml")
or trigger_error("Error while opening PCML file", E_USER_ERROR);

// Prepare the program
($hdlPgm = i5_program_prepare_PCML($description))
or trigger_error("Error while parsing PCML: " . i5_errormsg(),
E_USER_ERROR);

// Define input values
$in_parameters = Array("IOARRAY"=>array("One","Two","Three","Four"));

// And output variables
$out_parameters = array("IOARRAY"=>"IOARRAY");

echo "<br>Here's the input parms: ";
var_dump($in_parameters);

// Make the call
i5_program_call($hdlPgm, $in_parameters, $out_parameters)
or trigger_error("Error while executing program: " . i5_errormsg(),
E_USER_ERROR);

echo "<br><br>And here's the resulting output: ";
var_dump($IOARRAY);

?>

And here's the RPG program. The Printer part was introduced because I
couldn't tell where the failures were occurring.

FQprint O F 132 Printer

D Array Pr ExtPgm('ARRAY/PARTNER400')
D IOArray 5a Dim(4)

D Array PI
D IOArray 5a Dim(4)

D x S 5i 0

/Free
except info;
For x = 1 to %Elem(IOArray);
IOArray(x) = %Char(x);
EndFor;
except info;

*InLR = *On;
/End-Free

OQprint E info 2
O IOArray(1) 12
O IOArray(2) 24

Hope this helps.

We could certainly do with a few more examples of this type of program
call.
