What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.



pg_put_line — Sends a null-terminated string to a back-end server.


int pg_put_line([conn], data);
int conn (optional): Connection ID
string data: Data to insert


TRUE on success; FALSE on error


Sends a null-terminated string to the PostgreSQL server back end initiated by the COPY() SQL statement. The COPY statement expects data to be tab-delimited, as demonstrated in the following example.

While the NULL terminator is sent automatically, "\." must be sent to indicate that all data has been sent. When sending backslashes in your application, remember to escape them with another backslash (\\) as shown in the example.

pg_exec($db, "CREATE TABLE mydata (id int4, name char(16), ratio float8)");
pg_exec($db, "COPY bar FROM stdin");

foreach ($file as $line) {
    $tmp = explode(",", $line);
    pg_put_line($db, sprintf("%d\t%s\t%.2f\n", $tmp[0], $tmp[1], $tmp[2]));

pg_put_line($db, "\\.\n");
