pg_delete - Deletes records

SYNOPSIS

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

DESCRIPTION

       pg_delete(3)  deletes  records  from  a	table specified by the keys and values in $assoc_array. If $options is specified, pg_convert(3) is
       applied to $assoc_array with the specified options.

PARAMETERS

	      o $connection
		- PostgreSQL database connection resource.

	      o $table_name
		- Name of the table from which to delete rows.

	      o $assoc_array
		- 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
		deleted.

	      o $options
		-  Any	number	of PGSQL_CONV_FORCE_NULL, 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(3) internally.

RETURN VALUES

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

EXAMPLES

       Example #1

	      pg_delete(3) example

	      <?php
		$db = pg_connect('dbname=foo');
		// This is safe, since $_POST is converted automatically
		$res = pg_delete($db, 'post_log', $_POST);
		if ($res) {
		    echo "POST data is deleted: $res
";
		} else {
		    echo "User must have sent wrong inputs
";
		}
	      ?>
