限时送ChatGPT账号..
我正在尝试传递一个包含键和值的数组.
I am trying to pass a array that contains keys and values.
键是列,值是要选择的值.
The keys are columns and values are the values to select.
我正在尝试编写一个函数,我可以在其中传递数组并将键和值用作表的列和值.例如:
I am trying to write a function where I can pass a array and use the key and values as the column and values of a table. for example:
$array = array("user"=>"joe", user_id="2");
我需要像这样创建 sql 语句:
I need the sql statement to be created like so:
select * from table where $key = $value;
推荐答案
您可以像这样构建一个简单的 SQL Select:
You can build a simple SQL Select like so:
<?php
/**
* @param array Column => Value pairs
* @return string
*/
function create_sql_select(array $pair){
$condition = array();
foreach ( $pair as $key => $value){
$condition[] = "{$key} = '{$value}'";
}
// Separate by AND delimiter if there are more than 1 pair
$condition = join(' AND ', $condition);
// Return prepared string:
return "SELECT * FROM your_table WHERE {$condition}";
}
//Will print: SELECT * FROM your_table WHERE user = 'some' AND age = '10'
print create_sql_select(array('user' => 'some', 'age' => 10));
