将 SQL 查询字符串转换为数组格式 [关闭]

Question

<?php 
$str = "INSERT INTO `f_part` (lname,fname,email)  VALUES ('tha','thia','thia@gmail.com')";
?>

任何人都可以帮我将此字符串转换为数组

$result = array('table'=>'f_part',
                'data'=>array('lname=>'tha','fname=>'thia','email'=>'thia@gmail.com')

            )

您需要通过查找不同的 MySQL 关键字来分析查询，例如 INSERT、SELECT、INTO、VALUES、FROM、WHERE 等。但是，这可能会变得棘手和困难，因为您必须注意单引号，转义字符等。

我建议你只使用http://code.google.com/p/php-sql-parser/。该课程已经完成了棘手的部分。它与您想要的输出并不完全相同，但它会为您提供类似的东西，甚至更多。

这是一个示例查询：

SELECT STRAIGHT_JOIN a,b,c 
  from some_table an_alias
 WHERE d > 5;

以及示例输出：

Array
( 
    [OPTIONS] => Array
        (
            [0] => STRAIGHT_JOIN
        )       

    [SELECT] => Array
        (
            [0] => Array
                (
                    [expr_type] => colref
                    [base_expr] => a
                    [sub_tree] => 
                    [alias] => `a`
                )

            [1] => Array
                (
                    [expr_type] => colref
                    [base_expr] => b
                    [sub_tree] => 
                    [alias] => `b`
                )

            [2] => Array
                (
                    [expr_type] => colref
                    [base_expr] => c
                    [sub_tree] => 
                    [alias] => `c`
                )

        )

    [FROM] => Array
        (
            [0] => Array
                (
                    [table] => some_table
                    [alias] => an_alias
                    [join_type] => JOIN
                    [ref_type] => 
                    [ref_clause] => 
                    [base_expr] => 
                    [sub_tree] => 
                )

        )

    [WHERE] => Array
        (
            [0] => Array
                (
                    [expr_type] => colref
                    [base_expr] => d
                    [sub_tree] => 
                )

            [1] => Array
                (
                    [expr_type] => operator
                    [base_expr] => >
                    [sub_tree] => 
                )

            [2] => Array
                (
                    [expr_type] => const
                    [base_expr] => 5
                    [sub_tree] => 
                )

        )

)
