我是PHP新手，我正在尝试在命名数组中应用命名数组。我已经能够应用每个绳索名称（即“Poly Soak”）以及img，title，blurb，desc等，但是我很难尝试将$specTable应用到表格中。我也试图申请$applications和$benefits但没有运气。
我正在使用GET命令生成每个页面。页面填充如下：
water-rescue-ropes.php？value = aqua-d
water-rescue-ropes.php？value = poly-soak ... etc
function strip_bad_chars( $input ) {
$output = preg_replace( "/[^a-zA-Z0-9_-]/", "", $input );
return $output; }
if (isset($_GET['value'])) {
$waterRescueRope = strip_bad_chars( $_GET['value'] );
$rope = $waterRescueRopes[$waterRescueRope];}
以下是 已编辑的 数组信息：
$waterRescueRopes = array(
"poly-soak" => array(
'img' => "3P",
'title' => "Poly Soak™",
'blurb' => "Pelican’s 16 strand kernmantle construction is a...",
'desc' => "Polypropylene Water Rescue Rope",
'construction' => "16 Strand",
'cover' => "Polypropylene",
'core' => "Polypropylene",
array(
array(
'sku' => "3P-12Y",
'diameter' => "3/8"",
'tensile' => 3000,
'weight' => 3.4,
),
array(
'sku' => "3P-14Y",
'diameter' => "7/16"",
'tensile' => 3380,
'weight' => 4.7,
),
),
array("Water Rescue", "Canyoneering"),
array("Lightweight", "Buoyant", "High Visibility"),
),
"poly-soak-economy" => array(
'img' => "FQK",
'title' => "Poly Soak™ Economy",
'blurb' => "All the great benefits and features of our Poly Soak rope but at a lower cost.",
'desc' => "Polypropylene Economy Water Rescue Rope",
'construction' => "16 Strand",
'cover' => "Polypropylene",
'core' => "Polypropylene",
array(
array(

'diameter' => "1/8"",
'tensile' => 2000,
'weight' => 1.5,
),
),
array("Water Rescue"),
array("Economical", "Lightweight", "Buoyant"),
),
"poly-soak-2" => array(
'img' => "3PN",
'title' => "Poly Soak™",
'blurb' => "This UL certified polypropylene rope is approved for...",
'desc' => "NFPA® Water Rescue Rope",
'construction' => "24 Strand",
'cover' => "Polypropylene",
'core' => "Polypropylene",
array(
array(
'sku' => "3PN-12Y",
'diameter' => "3/8"",
'tensile' => 4200,
'weight' => 3.05,
),
),
array("Water Rescue", "Canyoneering", "Mooring"),
array("Bright Colors for Greater Visibility", "Supple for Compact Storage", "Certified to the Highest Standard", "Buoyant"),
),
"aqua-d" => array(
'img' => "3q",
'title' => "Aqua-D™",
'blurb' => "This water rescue rope has a blended Dyneema® and polypropylene core. With a multifilament polypropylene cover, this rope floats and has near zero water retention. It is extremely strong, light 'weight', and has a no-stretch braid that meets the needs of coastal and river rescue professionals worldwide.",
'desc' => "Dyneema® Polypropylene Water Rescue Rope",
'construction' => "16 Strand",
'cover' => "Polypropylene",
'core' => "Dyneema®",
array(
array(
'sku' => "3Q-08Y",
'diameter' => "1/4"",
'tensile' => "3200",
'weight' => "1.7",
),
array(
'sku' => "3Q-10Y",
'diameter' => "5/16"",
'tensile' => "3400",
'weight' => "2.3",
),
array(
'sku' => "3Q-12Y",
'diameter' => "3/8"",
'tensile' => "4950",
'weight' => "3.4",
),
),
array("Minimal Water Retention", "Strong & Lightweight", "Buoyant"),
array("Water Rescue"),
), );
其他附加功能：
function get_specs($array = false)
{
if (!is_array($array))
return array();
elseif(empty($array))
return array();
foreach($array as $polytype => $polydata) {
$new[$polytype]['specs'] = (!empty($polydata[0]))? $polydata[0]:array();
$new[$polytype]['applications'] = (!empty($polydata[1]))? $polydata[1]:array();
$new[$polytype]['benefits'] = (!empty($polydata[2]))? $polydata[2]:array();
}
return $new;
}
以下是 已编辑的 specTable：
<?php function display_specs($spec = array(),$name = false)
{
if(!empty($spec[$name]['specs'])) {
ob_start();
foreach($spec[$name]['specs'] as $specs) {
?>
<tr>
<td><?php echo $specs['sku']; ?></td>
<td><?php echo $specs['diameter']; ?></td>
<td><?php echo $specs['tensile']; ?></td>
<td><?php echo $specs['weight']; ?></td>
</tr>
<?php
}
$data = ob_get_contents();
}
} ?>
// Isolates the specs from the main array
$specs = get_specs($waterRescueRopes);
// Alternately, you can loop through the main array and get all
<?php foreach($specs as $polytype => $spec) {
echo display_specs($specs,$_GET['value']);
}
?>
已编辑 应用程序（优势在类似列表中）：
<?php function display_applications($spec = array(),$name = false)
{
if(!empty($spec[$name]['applications'])) {
ob_start();
foreach($spec[$name]['applications'] as $apps) {
?>
<li><?php echo $apps; ?></li>
<?php
}
$data = ob_get_contents();
return $data;
}
}
?>
<tr valign='top'>
<td class="td-item-cell"><article>
<div class="rel_product_wrapper">
<h3>Applications</h3>
<ul>
<li>
<?php
foreach($specs as $polytype => $spec) {
echo display_applications($specs,$_GET['value']);
}
?>
</li>
</ul>
</div>
</article></td>
</tr>
我目前让他们填充我需要的东西但多次（四种类型的绳子，我假设四次）。
感谢您的时间！我很感激！ ：）

删除数组中的变量，然后创建一个函数来单独提取所需的那些方面。你正在做什么不起作用的原因是每次你在每个数组上写$specTable时，你重新分配/覆盖先前分配的$specTable到当前数组，直到最后它被分配到最后一个主阵列中的数组。这就是为什么只有一个出现的原因。您需要将这些方面保存到新阵列：
功能：将功能放在页面顶部或您在此页面上包含的其他文件中以供使用。最好包括使用类似include("function.specs.php")的内容，因为如果需要，您可以在不同页面上重复使用这些功能。
function get_specs($array = false)
{
if (!is_array($array))
return array();
elseif(empty($array))
return array();
foreach($array as $polytype => $polydata) {
$new[$polytype]['specs'] = (!empty($polydata[0]))? $polydata[0]:array();
$new[$polytype]['applications'] = (!empty($polydata[1]))? $polydata[1]:array();
$new[$polytype]['benefits'] = (!empty($polydata[2]))? $polydata[2]:array();
}
return $new;
}
function display_specs($spec = array(),$name = false)
{
if(!empty($spec[$name]['specs'])) {
ob_start();
foreach($spec[$name]['specs'] as $specs) {
?>
<tr>
<td><?php echo $specs['sku']; ?></td>
<td><?php echo $specs['diameter']; ?></td>
<td><?php echo $specs['tensile']; ?></td>
<td><?php echo $specs['weight']; ?></td>
</tr>
<?php
}
$data = ob_get_contents();
return $data;
}
}
// For sake of ease, you can do an application one by itself,
// Normally, you could just do one class/method that handles all the
// the different arrays
function display_applications($spec = array(),$name = false)
{
if(!empty($spec[$name]['applications'])) {
ob_start();
foreach($spec[$name]['applications'] as $apps) {
?>
<tr>
<td><?php echo $apps; ?></td>
</tr>
<?php
}
$data = ob_get_contents();
return $data;
}
}
使用页面上的功能
// Isolates the specs from the main array
$specs = get_specs($waterRescueRopes);
// To select one product out of the bunch, just use the name from the array.
// Note, you need the $specs array as the first argument
echo display_specs($specs,"poly-soak");
echo display_applications($specs,"poly-soak");
// Alternately, you can loop through the main array and get all: ?>
<table>
<?php
foreach($specs as $polytype => $spec) {
echo display_specs($specs,$polytype);
echo display_applications($specs,$polytype);
}
?>
</table>
应用程序部分：因为该函数已经为您完成了循环，所以您只需要回显它：
<tr valign='top'>
<td class="td-item-cell"><article>
<div class="rel_product_wrapper">
<h3>Applications</h3>
<ul>
<li>
<?php echo display_applications($specs,$_GET['value']); ?>
</li>
</ul>
</div>
</article></td>
</tr>
