Hi folks.
I have an interesting problem with regards to variable scope in loops.
Now I understand how this operates in functions but its the first time I
have seen variable scope in a loop.
Below is a code snippet of what I have:
// execute SQL query
OCIExecute($sql_statement) or die("Couldn't execute statement.");
// get number of columns for use later
$num_columns = OCINumCols($sql_statement);
// format results by row
while (OCIFetch($sql_statement)) {
for ($i = 1; $i < $num_columns+1; $i++) {
// Create array to store fetch results
$incident_array[i] = OCIResult($sql_statement,$i);
//echo "<P>Incident array value $i: $incident_array[i]</P>";
}
}
// Output results of incident array
echo "<P>First array value: $incident_array[1]</P>";
Now I 'expected' the echo statement to properly display the results of
the first array element but instead, the value is blank. Now when I
uncomment the echo statement WITHIN the for loop, it does display so I
know the values are being stored but apparantly the scope of the array
is within the loop and not outside.
How can I make the array values accessible outside of the loop? I found
a 'global' statement in the documentation but it didn't seem to like
taking an array as a parameter. I had it looking something like this:
global $incident_array[];
Any help would be appreciated.
