hi.

i have the following test multidiminsional array. i'm trying to figure out
how to iterate through the array, to produce something like

foo, physics, sss
foo, physics, sffgg
foo, english, sss
foo, english, sffgg

can't quite seem to get it right!!

thoughts/comments... etc...

thanks

--------------------
$a=array("college"=> "foo",
"dept"=>array("dept"=> "physics",
"class"=>array("class1"=>"sss","class2"=>"sffg g")
),
"dept"=>array("dept"=> "english",
"class"=>array("class1"=>"sss","class2"=>"sffg g")
)
);

robert

You can't. You're array is valid but the second 'dept' key overwrites
the first. Thus the physics dept is lost.

Check it for yourself... print_r( $a )

Cheers,
Rob.

hey robert..

ok.. so if i changed the array to have a dept1, and a dept2

$a=array("college"=> "foo",
"dept1"=>array("dept"=> "physics",
"class"=>array("class1"=>"sss","class2"=>"sffg g")
),
"dept2"=>array("dept"=> "english",
"class"=>array("class1"=>"sss","class2"=>"sffg g")
)
);
how would i iterate through this..??

thanks

Your array is terribly structured. But the following provides traversal
in the way you want:

<?php
$a = array (
"college" => "foo",
"dept1" => array (
"dept" => "physics",
"class" => array (
"class1" => "sss",
"class2" => "sffgg" ) ),
"dept2" => array (
"dept" => "english",
"class" => array (
"class1" => "sss",
"class2" => "sffgg"
)
)
); $college = $a['college'];
foreach( $a as $deptKey => $deptInfo )
{
if( strpos( $deptKey, 'dept' ) === 0 )
{
$dept = $deptInfo['dept'];
foreach( $deptInfo['class'] as $class )
{
echo "$college, $dept, $class\n";
} } }
?>

Rob.

hey robert!!

thanks. and yeah, you're right, it's not the best.. so tell me, given that
i'm ripping through this on the fly, and i can have the structure in any way
i choose. this is just to simulate/populate some test tbls.. what's a better
way to create an array structure to have a collegename, followed by some
deptnames, followed by some classnames for the depts...

perhaps something like this??

$a = array
(
"college" => "foo",
array
(
"dept" => "physics",
"class" => array
(
"class1" => "sss",
"class2" => "sffgg"
)
),
array
(
"dept" => "english",
"class" => array
(
"class1" => "sss",
"class2" => "sffgg"
)
)
);

Not quite. The following is probably what you want:

<?php

$colleges = array
( array (
'name' => 'Blah Blah University',
'depts' => array
( array (
'name' => 'physics',
'classes' => array
(
'sss',
'sffgg',
),
), array (
'name' => 'english',
'classes' => array
(
'sss',
'sffgg',
),
),
),
), array (
'name' => 'Glah Gleh University',
'depts' => array
( array (
'name' => 'physics',
'classes' => array
(
'sss',
'sffgg',
),
), array (
'name' => 'english',
'classes' => array
(
'sss',
'sffgg',
),
),
),
),
);

foreach( $colleges as $college )
{
$collegeName = $college['name'];
foreach( $college['depts'] as $dept )
{
$deptName = $dept['name'];
foreach( $dept['classes'] as $className )
{
echo "$collegeName, $deptName, $className\n";
} } }
?>

Cheers,
Rob.

This is actually a much smaller data structure.
$colleges = array (
'Blah Blah University' => array (
'physics' => array
(
'sss', 'sffgg', ),
'english' => array
(
'sss',
'sffgg', ) ),
'Glah Gleh University' => array (
'physics' => array
(
'sss', 'sffgg', ),
'english' => array
(
'sss',
'sffgg',
),
) );
foreach( $colleges as $collegeName => $depts ) {
foreach( $depts as $deptName => $classes)
{
foreach( $classes as $className )
{
echo "$collegeName, $deptName, $className\n";
}
}
}

Yes, I thought of that one too, but it's less flexible. What if you need
to add other fields to the college, or department. Then you'd need to
redo the whole structure to something more similar to what I did. Since
bruce was having issues, I gave him a flexible format that could handle
other fields if they arose.

Cheers,
Rob.

both ways work...!!!

this is a really simple/quick issue to populate some test db tbls.. i've
only played with multi php arrays (sp??) in passing... and my days of being
a serious eng/software guy are long over!!

although.. with this economy!

thanks
