pg_delete

(PHP 4 >= 4.3.0, PHP 5, PHP 7)
Deletes records
mixed pg_delete ( resource $connection, string $table_name, array $assoc_array [, int $options = PGSQL_DML_EXEC ] )

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

Parameters:
connection

PostgreSQL database connection resource.

table_name

Name of the table from which to delete rows.

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.

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() internally.

Returns:

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

Changelog:
5.6.0

No longer experimental. Added PGSQL_DML_ESCAPE constant, TRUE/FALSE and NULL data type support.

5.5.3/5.4.19

Direct SQL injection to table_name and Indirect SQL injection to identifiers are fixed.

Examples:
pg_delete() 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\n";
  } else {
      echo "User must have sent wrong inputs\n";
  }
?>
