Clever solution to uncertain multi-condition query under fleaphp_PHP tutorial

Question: For example, the implementation is as follows:
$data = array(
'id' => );
$posts = $this->_modelstudent->findAll($data);
There is a text box with id name on the page, where you can enter the ID query, NAME query, or both;

Solution: Write a loop to make judgments
The example is as follows:
$conditions = null;
$fields = array('id', 'name', 'sex', 'phone');
foreach($fields as $each) {
if(!empty($_POST[$each])) {
if($conditions) {
$conditions .= " AND {$each }={$_POST[$each]}";
} else {
$conditions .= "{$each}={$_POST[$each]}";
}
}
}
