$sql1="INSERT INTO tble1 (name, father_name ,Mother_name,  age, blood_group)VALUES ('";
for($i=0;$i<count($values1);$i++) {
   if($i == count($values1)-1){
        $sql1 .= $values1[$i]."')";
        return 0;
   }
   $sql1 .= $values1[$i]."', '";
}

但你不应该这样做，因为这是危险的，它被称为“sql注入”
你必须这样做

$req = $bdd->prepare('INSERT INTO tble1(name, father_name ,Mother_name,  age, blood_group) VALUES(:name, :father_name , :Mother_name,  :age, :blood_group)');
$req->execute(array(
    'name' => $values1[0],
    'father_name' => $values1[1],
    'Mother_name' => $values1[2],
    'age' => $values1[3],
    'blood_group' => $values1[4]
    ));

如果你有这样一个数组

$values=[name,...., name, father_name, Mother_name, age, blood_group];

那就这样做吧

$values=array_chunk($values, 5);

for($i=0;$i<count($values);$i++) {
    $values1 = $values[$i];
$req = $bdd->prepare('INSERT INTO tble1(name, father_name ,Mother_name,  age, blood_group) VALUES(:name, :father_name , :Mother_name,  :age, :blood_group)');
$req->execute(array(
    'name' => $values1[0],
    'father_name' => $values1[1],
    'Mother_name' => $values1[2],
    'age' => $values1[3],
    'blood_group' => $values1[4]
    ));
}

例子
你的表格里有这样一个数组

$values=[name0, father_name0, Mother_name0, age0, blood_group0, name1, father_name1, Mother_name1, age1, blood_group1];

它包含两组数据 name0, father_name0, Mother_name0, age0, blood_group0 以及 name1, father_name1, Mother_name1, age1, blood_group1 它可能包含n组数据，但它们都有5个值，这就是为什么我使用

$values=array_chunk($values, 5);

它将数组拆分为n个（在本例中是2个数组）数组
完成后让我们回到我们的示例 $values=array_chunk($values, 5); 值将等于

$values=[[name0, father_name0, Mother_name0, age0, blood_group0], [name1, father_name1, Mother_name1, age1, blood_group1]];

使用for循环，我们将像这样循环这些子数组

for($i=0;$i<count($values);$i++) {
   $values1 = $values[$i];
   ....
}

对于要多次添加相同值的js代码，请改为这样做

var arrayA = [];
function addvalues()

    var len = arrayA.length;
    for(let i=len; i<$('[name=data]').length; i++){
        if($('[name=data]')[i].val() || $('[name=data]')[i].val()==0){//if you aren't sure that these values can be null or not. Delete this line if you think that they can't be null.
           arrayA.push($('[name=data]')[i].val());
        }
     }

}

对于insert函数，也可以这样做

function insert(){
       $.ajax({  
             url:'insert.php',  
             method:"POST",  
             data:{  details: arrayA},  
             success:function(data){  
                             //alert(html);
                     }  
       });  
    }
