PHP obfuscate_mailto函数代码示例

/**
 * Get a list of fields to be displayed in lists of users, etc.
 *
 * The input of the function is a user record;
 * possibly null, in this case the function should return only the field titles.
 *
 * The function returns an array of objects that describe user data fields.
 * Each of these objects has the following properties:
 *  $field->title : Displayable title of the field
 *  $field->value : Value of the field for this user (not set if $user is null)
 *
 * @param stdClass $user the user record; may be null
 * @return array an array of field objects
