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";
}
}
}
?>
Cheers,
Rob.
