php implode(101)with quotes

Question

扼杀一个简单的数组

看起来像这样

$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);

那会回来的

 lastname,email,phone

很棒,所以我可能会这样做

$array = array('lastname', 'email', 'phone');
$comma_separated = implode("','", $array);
$comma_separated = "'".$comma_separated."'";

现在我有我想要的漂亮的csv字符串

 'lastname','email','phone'

有没有更好的方法来做到这一点,我觉得应该有一个可选参数implode我错过了什么？

Answer 1

$array = array('lastname', 'email', 'phone');


echo "'" . implode("','", $array) . "'";

Answer 2

function add_quotes($str) {
    return sprintf("'%s'", $str);
}

$csv =  implode(',', array_map('add_quotes', $array));

另请注意,fputcsv如果要写入文件.

Answer 3

不,你这样做的方式很好.implode()只需要1-2个参数(如果你只提供一个数组,它会用空字符串连接它们).

Answer 4

$ids = sprintf("'%s'", implode("','", $ids ) );

Answer 5

不知道它是否更快,但是,您可以使用您的方法保存一行代码:

从

$array = array('lastname', 'email', 'phone');
$comma_separated = implode("','", $array);
$comma_separated = "'".$comma_separated."'";

至:

$array = array('lastname', 'email', 'phone');
$comma_separated = "'".implode("','", $array)."'";

Answer 6

如果你想使用循环,你也可以这样做:

$array = array('lastname', 'email', 'phone');
foreach($array as &$value){
   $value = "'$value'";
}
$comma_separated = implode(",", $array);

Answer 7

$id = array(2222,3333,4444,5555,6666);
$ids = "'".implode("','",$id)."'";

Or

$ids = sprintf("'%s'", implode("','", $id ) );
