PHP:pg_escape_identifier()的用法_PostgreSQL函数

pg_escape_identifier

(PHP 5 >= 5.4.4)

pg_escape_identifier — Escape a identifier for insertion into a text field

说明

string pg_escape_identifier ([ resource $connection ], string $data )

pg_escape_identifier() escapes a identifier (e.g. table, field names) for quering the database. It returns an escaped identifier string for PostgreSQL server. pg_escape_identifier() adds double quotes before and after data. Users should not add double quotes. Use of this function is recommended for identifier parameters in query. For SQL literals (i.e. parameters except bytea), pg_escape_literal() or pg_escape_string() muse be used. For bytea type fields, pg_escape_bytea() must be used instead.

Note:

This function has internal escape code and can also be used with PostgreSQL 8.4 or less.

参数

connection

PostgreSQL database connection resource. When connection is not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().

data

A string containing text to be escaped.

返回值

A string containing the escaped data.

范例

Example #1 pg_escape_identifier() example

<?php 
  // Connect to the database
  $dbconn = pg_connect('dbname=foo');
  
  // Escape the table name data
  $escaped = pg_escape_identifier($table_name);
  
  // Select rows from $table_name
  pg_query("SELECT * FROM {$escaped};");
?>
