Re: PHP Syntax Question -- WEB400

I'm not a php developer, but one thing that struck me is that your code used both array() and Array() constructors. Are array constructors case sensitive in php? They are in JavaScript.

Subject: [WEB400] PHP Syntax Question

Hi,

I posted this question on Zend's forum but got no response so hopefully one
of the PHP users on here can provide some insight to me on this.

I am having trouble understanding why I cannot print the contents of a
returned PHP array from an I5_Program_Call.

It could be because of the way the data structure array(s) are defined in my
RPGLE program and that I am not defining them correctly in my PHP script.

============================================================================
==================================================

Here's the PCML (it's pretty short)

<pcml version="4.0">









<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>

</pcml>

============================================================================
==============

And this is the relevant portion of the PHP Script (also short)

$in_parameters = Array( "KSOCKCN"=>"20",

"KSOCKYR"=>"05",

"KSOCKTY"=>"TR",

"KSOCKNO"=>"000054");

$out_parameters = array(

"OUT_NAME"=>"OUT_NAME",

"OUT_TICKET"=>"OUT_TICKET",

"OUT_ARRAY"=>Array("OUT_NAME1"=>"OUT_NAME1",

"OUT_TICKET1"=>"OUT_TICKET1"));

i5_program_call($hdlPgm, $in_parameters, $out_parameters);

echo "Out_Name is: <font color='red'><h2>".$OUT_NAME."</h2></font> and that
was the value of the Out_Name field<BR><BR>";

echo "Out_Ticket is: <font color='red'><h2>".$OUT_TICKET."</h2></font> and
that was the value of the Out_Ticket field<BR><BR>";

echo "Out_Name1 is: <font
color='blue'><h2>".$out_parameters["OUT_ARRAY"]["OUT_NAME1"][1]."</h2></font

and that was the value of the first array element<br><br>";

============================================================================
============================================================================
=====================================================

When I execute the PRINT statements at the end of the script, the values in
the fields OUT_NAME and OUT_TICKET print the contents just fine that were
returned from the RPG program.

But the values in the data structure array, OUT_ARRAY, and the fields
OUT_NAME1 and OUT_TICKET1 only print the values "OUT_NAME1" and
"OUT_TICKET1" which is the names of the local variables that I thought would
contain the returned data. Or, if I try to print just a single element, I
get whatever character is at that position in that variable name such as
print $out_parameters["OUT_ARRAY"]["OUT_NAME1"][1] would print the letter
"U".

So I am not understanding something here about how to define/refer to the
elements in an RPG data structure array in PHP.

I would appreciate any suggsetions on how to correclty define and print my
data structure arrays from the returned program call.

Thanks!
