Parsing sql query PHP
parsing, php, sql
Solution
Use an SQL parser. http://code.google.com/p/php-sql-parser/
Copy paste from this example:
<?php
require_once('php-sql-parser.php');
$parser=new PHPSQLParser('SELECT a FROM some_table an_alias WHERE d > 5;', true);
print_r($parser->parsed);
Example output:
Array
(
[SELECT] => Array
(
[0] => Array
(
[expr_type] => colref
[alias] =>
[base_expr] => a
[sub_tree] =>
[position] => 8
)
)
[FROM] => Array
(
[0] => Array
(
[expr_type] => table
[table] => some_table
[alias] => Array
(
[as] =>
[name] => an_alias
[base_expr] => an_alias
[position] => 29
)
[join_type] => JOIN
[ref_type] =>
[ref_clause] =>
[base_expr] => some_table an_alias
[sub_tree] =>
[position] => 18
)
)
[WHERE] => Array
(
[0] => Array
(
[expr_type] => colref
[base_expr] => d
[sub_tree] =>
[position] => 45
)
[1] => Array
(
[expr_type] => operator
[base_expr] => >
[sub_tree] =>
[position] => 47
)
[2] => Array
(
[expr_type] => const
[base_expr] => 5
[sub_tree] =>
[position] => 49
)
)
)
Problem
I want to parse a SQL query into an array. I could not figure out the code. Example: ``` $sql_query = "SELECT id, login, pass FROM users WHERE id=3, login=faforty ORDER DESC LIMIT 3"'; ``` and this sql query should be as follows: ``` $data = array(); $data['select'] = array('id', 'login', 'pass'); $data['from'] = array('id' => 3, 'login' => 'faforty'); $data['order'] = 'desc'; $data['limit'] = 3; ``` Query may be different.
