PHP Manual :: pg_insert

pg_host || pg_last_error || PostgreSQL Functions || PHP Manual

(PHP 4 >= 4.3.0, PHP 5, PHP 7)

pg_insert Insert array into table


mixed pg_insert ( resource $connection , string $table_name , array $assoc_array [, int $options = PGSQL_DML_EXEC ] )

pg_insert() inserts the values of assoc_array into the table specified by table_name. If options is specified, pg_convert() is applied to assoc_array with the specified options.



PostgreSQL database connection resource.


Name of the table into which to insert rows. The table table_name must at least have as many columns as assoc_array has elements.


An array whose keys are field names in the table table_name, and whose values are the values of those fields that are to be inserted.


Any number of PGSQL_CONV_OPTS, PGSQL_DML_NO_CONV, PGSQL_DML_ESCAPE, PGSQL_DML_EXEC, PGSQL_DML_ASYNC or PGSQL_DML_STRING combined. If PGSQL_DML_STRING is part of the options then query string is returned. When PGSQL_DML_NO_CONV or PGSQL_DML_ESCAPE is set, it does not call pg_convert() internally.

Return Values

Returns TRUE on success or FALSE on failure. Returns string if PGSQL_DML_STRING is passed via options.


Example #1 pg_insert() example

// This is safe, since $_POST is converted automatically
$res pg_insert($dbconn'post_log'$_POST);
  if (
$res) {
"POST data is successfully logged\n";
  } else {
"User must have sent wrong inputs\n";
