数组php中的addor合并字段

Question

这是代码的一部分：

$toExport = array(
            array('c.id_customer','"[quickid]"'),
            array('c.firstname','"[name]"'),
        array('c.lastname','"[lastname]"'),
            array('c.siret','"[hej]"'),
            array('c.email','"[email]"'),
);

我想在[name]中合并c.firstname和c.lastname，如果这是正确的术语？ 像这样的东西：

$toExport = array(
            array('c.id_customer','"[quickid]"'),
            array('c.firstname + c.lastname','"[name]"'),
            array('c.siret','"[hej]"'),
            array('c.email','"[email]"'),
);

我知道最后一段代码超级错误，但有可能吗？

这是整个代码：
