Do it all in the database, if possible.
If you _really_ have to mix sql/plsql and shell programming:

- as array in bash:

Code:
$ var1="($(printf "%s \n" "set pages 0 feed off" \
> "select ename from emp;"|sqlplus -s scott/tiger))"; \
> printf "The first element in \$var1 array is: %s, \
> the second: %s and so on ...\n" \
> "${var1[1]}" "${var1[2]}"
The first element in $var1 array is: ALLEN, the second: WARD and so on ...

- as a single variable:

Code:
$ var1="$(printf "%s \n" "set pages 0 feed off" \
> "select ename from emp;"|sqlplus -s scott/tiger)"; \
> echo "Quoted: $var1"; \
> echo "Unquoted:" $var1
Quoted: SMITH
ALLEN
WARD
JONES
MARTIN
BLAKE
CLARK
SCOTT
KING
TURNER
ADAMS
JAMES
FORD
MILLER
Unquoted: SMITH ALLEN WARD JONES MARTIN BLAKE CLARK SCOTT KING TURNER ADAMS JAMES FORD MILLER

I'm sure that it will be better
if you use only one programming language.

LIST(3) 								 1								   LIST(3)

list - Assign variables as if they were an array

SYNOPSIS
array list (mixed $var1, [mixed $...]) DESCRIPTION
Like array(3), this is not really a function, but a language construct. list(3) is used to assign a list of variables in one operation. PARAMETERS
o $var1 - A variable. RETURN VALUES
Returns the assigned array. EXAMPLES
Example #1 list(3) examples <?php $info = array('coffee', 'brown', 'caffeine'); // Listing all the variables list($drink, $color, $power) = $info; echo "$drink is $color and $power makes it special. "; // Listing some of them list($drink, , $power) = $info; echo "$drink has $power. "; // Or let's skip to only the third one list( , , $power) = $info; echo "I need $power! "; // list() doesn't work with strings list($bar) = "abcde"; var_dump($bar); // NULL ?> Example #2 An example use of list(3) <table> <tr> <th>Employee name</th> <th>Salary</th> </tr> <?php $result = $pdo->query("SELECT id, name, salary FROM employees"); while (list($id, $name, $salary) = $result->fetch(PDO::FETCH_NUM)) { echo " <tr> " . " <td><a href="info.php?id=$id">$name</a></td> " . " <td>$salary</td> " . " </tr> "; } ?> </table> Example #3 Using nested list(3) <?php list($a, list($b, $c)) = array(1, array(2, 3)); var_dump($a, $b, $c); ?> int(1) int(2) int(3) Example #4 Using list(3) with array indices <?php $info = array('coffee', 'brown', 'caffeine'); list($a[0], $a[1], $a[2]) = $info; var_dump($a); ?> Gives the following output (note the order of the elements compared in which order they were written in the list(3) syntax): array(3) { [2]=> string(8) "caffeine" [1]=> string(5) "brown" [0]=> string(6) "coffee" } NOTES
Warning list(3) assigns the values starting with the right-most parameter. If you are using plain variables, you don't have to worry about this. But if you are using arrays with indices you usually expect the order of the indices in the array the same you wrote in the list(3) from left to right; which it isn't. It's assigned in the reverse order. Warning Modification of the array during list(3) execution (e.g. using list($a, $b) = $b) results in undefined behavior. Note list(3) only works on numerical arrays and assumes the numerical indices start at 0. SEE ALSO
each(3), array(3), extract(3). PHP Documentation Group LIST(3)
