How to use the find function in fleaphp crud operation_PHP tutorial

Prototype of find function

Copy code The code is as follows:

/**
* Returns the first record that meets the conditions and all associated data. If the query has no result, it returns false
*
* @param mixed $conditions
* @param string $sort
* @ param mixed $fields
* @param mixed $queryLinks
*
* @return array
*/
function & find ($conditions, $sort = null, $fields = '*', $queryLinks = true)
{
$rowset =& $this->findAll($conditions, $sort, 1, $fields, $queryLinks);
if (is_array($rowset)) {
$row = reset($rowset);
} else {
$row = false;
}
unset ($rowset);
return $row;
}

$conditions,
$sort = null,
$fields = '*'
$queryLinks = true
$conditions = null, query conditions
usually array , including field name and value
