在php中打印数组数组的值

我正在用一个for填充一个数组，这将他发送给一个角色，她将接收并使用foreach我将数组的值分配给我的变量并打印，但是，只有值的第一个数组和其他节目被忽略。

此代码填充数组

$return_arr = array();

for ($i=0;$i<$cont-1;$i++)
{
    /* the mysql code for insert multiple data*/


    //The array
    $row_array[$i]['idTicket'] = $idTicket;
    $row_array[$i]['porcionSubtotal'] = $porcionSubtotal[$i];
    $row_array[$i]['cajero'] = $cajero;
    $row_array[$i]['porcionCant'] = $porcionCant[$i];
    $row_array[$i]['tipoPago'] = $tipoPago;
    $row_array[$i]['marca'] = $marca;
    $row_array[$i]['descuento'] = $descuento;
    $row_array[$i]['nombreProducto'] = $nombreProducto;
}

array_push($return_arr, $row_array);
crearTicketVenta($return_arr, $total);

我的pdf函数是

function crearTicketVenta($return_arr, $totalVenta){
$total = $totalVenta;
foreach($return_arr as $index => $value){

        $nombre = $value[$index]['nombreProducto'] .'<br>';
        $cantidad = $value[$index]['porcionCant'] .'<br>';
        $importe = $value[$index]['porcionSubtotal'] .'<br>';
        $subtotal = $value[$index]['porcionSubtotal'] .'<br>';
        $idTicket = $value[$index]['idTicket'];
        $cajero = $value[$index]['cajero'];
        $porcionSubtotal = $value[$index]['porcionSubtotal'];
        //unset($return_arr[$index + 1]);
    }
}

并且var_dump数组是

array(1) { [0]=> array(2) { [0]=> array(8) { ["idTicket"]=> int(160) ["porcionSubtotal"]=> string(2) "21" ["cajero"]=> string(9) "undefined" ["porcionCant"]=> string(1) "1" ["tipoPago"]=> string(9) "undefined" ["marca"]=> string(5) "ADATA" ["descuento"]=> string(1) "%" ["nombreProducto"]=> string(7) "Carrito" } [1]=> array(8) { ["idTicket"]=> int(160) ["porcionSubtotal"]=> string(3) "135" ["cajero"]=> string(9) "undefined" ["porcionCant"]=> string(1) "1" ["tipoPago"]=> string(9) "undefined" ["marca"]=> string(12) "LIDeditorial" ["descuento"]=> string(1) "%" ["nombreProducto"]=> string(30) "Las cuatro Vidas de Steve Jobs" } } }

仔细查看您的数据：

array(1) { [0]=> array(2) { [0]=> array(8) { ["idTicket"]=> int(160)    ["porcionSubtotal"]=> string(2) "21" ["cajero"]=> string(9) "undefined" ["porcionCant"]=> string(1) "1" ["tipoPago"]=> string(9) "undefined" ["marca"]=> string(5) "ADATA" ["descuento"]=> string(1) "%" ["nombreProducto"]=> string(7) "Carrito" } [1]=> array(8) { ["idTicket"]=> int(160) ["porcionSubtotal"]=> string(3) "135" ["cajero"]=> string(9) "undefined" ["porcionCant"]=> string(1) "1" ["tipoPago"]=> string(9) "undefined" ["marca"]=> string(12) "LIDeditorial" ["descuento"]=> string(1) "%" ["nombreProducto"]=> string(30) "Las cuatro Vidas de Steve Jobs" } } }

array(1)

在显示数据时，您正在这样做

foreach($return_arr as $index => $value) {

    $nombre = $value[$index]['nombreProducto'] .'<br>';
    $cantidad = $value[$index]['porcionCant'] .'<br>';
    $importe = $value[$index]['porcionSubtotal'] .'<br>';
    $subtotal = $value[$index]['porcionSubtotal'] .'<br>';
    $idTicket = $value[$index]['idTicket'];
    $cajero = $value[$index]['cajero'];
    $porcionSubtotal = $value[$index]['porcionSubtotal'];
    //unset($return_arr[$index + 1]);
}

$return_arr只有一个值，这就是foreach显示一个条目的原因。

用作：foreach($return_arr[0] as $index => $value) {

或更改

array_push($return_arr, $row_array);至$return_arr = $row_array;

我解决了这个问题，谢谢你的答案。

这是我的代码的一部分，这部分会生成一个数组。

for ($i=0;$i<$cont-1;$i++){
    //the mysql query
    //the array
    $row_array[$i]['idTicket'] = $idTicket;
    $row_array[$i]['porcionSubtotal'] = $porcionSubtotal[$i];
    $row_array[$i]['cajero'] = $cajero;
    $row_array[$i]['porcionCant'] = $porcionCant[$i];
    $row_array[$i]['tipoPago'] = $tipoPago;
    $row_array[$i]['marca'] = $marca;
    $row_array[$i]['descuento'] = $descuento;
    $row_array[$i]['nombreProducto'] = $nombreProducto;
}
    //push the array
    array_push($return_arr, $row_array);
    //send array and value
    crearTicketVenta($return_arr, $total);

这是我的完整代码，此代码生成PDF凭证。

    <?php
function crearTicketVenta($return_arr, $totalVenta){
    // Include the main TCPDF library (search for installation path).
    require_once('includes/tcpdf/tcpdf.php');

//Define format date
date_default_timezone_set('America/Mexico_City');
$hoy = getdate();
$fechaActual= $hoy['mday'].'-'.$hoy['mon'].'-'.$hoy['year'];
$horaActual= $hoy['hours'].':'.$hoy['minutes'];

//Define variables
$total = $totalVenta;
$nombre = '';
$cantidad = '';
$importe = '';
$subtotal = '';
$idTicket = '';
$cajero = '';
$porcionSubtotal = '';

//The array
foreach($return_arr as $index => $value){   
    if(is_array($value)) {
       foreach ($value as $key => $values) {
            $nombre .= $values['nombreProducto'] .'<br>';
            $cantidad .= $values['porcionCant'] .'<br>';
            $importe .= $values['porcionSubtotal'] .'<br>';
            $subtotal .= $values['porcionSubtotal'] .'<br>';
            $idTicket = $values['idTicket'];//Don't repeat
            $cajero = $values['cajero'];//Don't repeat
            $porcionSubtotal .= $values['porcionSubtotal'];
        }
    }       
}
