How would I pass awk output to a perl variable?
For example, I want to save the value in the 4th column into the variable called test. My best guess is something as follow, but I am sure this isn't correct.

LEARN ABOUT PHP
sqlite_open
SQLITE_OPEN(3) SQLITE_OPEN(3)
sqlite_open - Opens an SQLite database and create the database if it does not exist
SYNOPSIS
resource sqlite_open (string $filename, [int $mode = 0666], [string &$error_message])
DESCRIPTION
Object oriented style (constructor): SQLiteDatabase::__construct (string $filename, [int $mode = 0666], [string &$error_message])
Opens an SQLite database or creates the database if it does not exist.
PARAMETERS
o $filename
- The filename of the SQLite database. If the file does not exist, SQLite will attempt to create it. PHP must have write permis-
sions to the file if data is inserted, the database schema is modified or to create the database if it does not exist.
o $mode
- The mode of the file. Intended to be used to open the database in read-only mode. Presently, this parameter is ignored by the
sqlite library. The default value for mode is the octal value 0666 and this is the recommended value.
o $error_message
- Passed by reference and is set to hold a descriptive error message explaining why the database could not be opened if there was
an error.
RETURN VALUES
Returns a resource (database handle) on success, FALSE on error.
EXAMPLES
Example #1
sqlite_open(3) example
<?php
if ($db = sqlite_open('mysqlitedb', 0666, $sqliteerror)) {
sqlite_query($db, 'CREATE TABLE foo (bar varchar(10))');
sqlite_query($db, "INSERT INTO foo VALUES ('fnord')");
$result = sqlite_query($db, 'select bar from foo');
var_dump(sqlite_fetch_array($result));
} else {
die($sqliteerror);
}
?>
NOTES
Tip
On Unix platforms, SQLite is sensitive to scripts that use the fork() system call. If you do have such a script, it is recommended
that you close the handle prior to forking and then re-open it in the child and/or parent. For more information on this issue, see
The C language interface to the SQLite library in the section entitled Multi-Threading And SQLite.
Tip
It is not recommended to work with SQLite databases mounted on NFS partitions. Since NFS is notoriously bad when it comes to lock-
ing you may find that you cannot even open the database at all, and if it succeeds, the locking behaviour may be undefined.
Note
Starting with SQLite library version 2.8.2, you can specify :memory: as the $filename to create a database that lives only in the
memory of the computer. This is useful mostly for temporary processing, as the in-memory database will be destroyed when the process
ends. It can also be useful when coupled with the ATTACH DATABASE SQL statement to load other databases and move and query data
between them.
Note
SQLite is safe mode and open_basedir aware.
