Bạn có thể tạo một SQL Select đơn giản như sau:
<?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));
