我正在尝试传递包含键和值的数组。
键是列,值是要选择的值。
我正在尝试编写一个函数,我可以传递一个数组,并使用键和值作为表的列和值。例如:
$array = array("user"=>"joe", user_id="2");
我需要像这样创建sql语句:
select * from table where $key = $value;

您可以像这样构建一个简单的SQL Select:
<?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));

使用foreach
循环迭代数组并获取键和值。像这样:
$sql='';
foreach($array as $key=>$value){
$sql = sprintf("select * from table where %s = %s",$key,$value);
print $sql;
}
