Here you have to use vsprintf()instead of sprintf().
在这里你必须使用vsprintf()而不是sprintf().
sprintf()accepts only plain variables as argument. But you are trying to pass an array as argument.
sprintf()只接受普通变量作为参数。但是您试图将数组作为参数传递。
For that purpose you need vsprintf()which accepts array as argument.
为此，您需要vsprintf()接受数组作为参数。
For example in your case:
例如在你的情况下：
"some text %s another text %s extra text %s"
and the array:
和数组：
$array[0] match the first %s
$array[1] match the second %s
$array[2] match the third %s
To achieve what you want you have to do the following:
要实现您想要的，您必须执行以下操作：
$output = vsprintf("some text %s another text %s extra text %s",$array);
echo $output;
Output:
输出：
some text match the first another text match the second extra text match the third
