我目前正在尝试搜索一些json结果（SKU和ID），如果找到我输入的字符串（SKU），我希望它显示产品ID。
我是新手，所以也许我完全走错了路。
这是我到目前为止所做的：
<?php
// Establish connection with TG
$context = stream_context_create(array(
'http' => array(
'header' => "Authorization: Bearer 872ed5e72dfc7e4e0adaa7c663cab7d81415078fdbe4f486d085b718c93b3eb3")
)
);
// API URL for TG
$url = "http://api.tradegecko.com/variants";
// Get the JSON information from TG
$data = file_get_contents($url, false, $context);
// Decode that motherfucker
$json = json_decode($data);
// Now for each item do something
foreach ($json->variants as $row) {
$getsku = $row->sku;
$getid = $row->id;
$check_sku = $getsku." - ".$getid;
// show decoded results
//echo $check_sku."<br>";
}
// Check to see if the SKU is there
$checking = array($check_sku);
// Search results for the string
$string = 'gini-gear';
// if the SKU matches the string, echo the product ID
foreach ($checking as $product_info) {
if (strpos($string, $product_info) !== FALSE) {
echo "The SKU was found, the ID is ".$getid;
return true;
}
}
echo "The SKU was not found, try again";
return false;
?>
解码的json结果如下。所以我正在寻找它以获取＆＃39; 6337393＆＃39;。但我得到的只是＆＃34;找不到SKU，再试一次＆＃34;。有人可以帮忙吗？
编辑：下面解码结果的完整列表。最初粘贴了一些以节省空间但添加了完整列表以帮助理解var_dump。

编辑：感谢Barmar！我已将其更改为以下（我认为是正确的）但它仍然找不到它。
<?php
// Establish connection with TG
$context = stream_context_create(array(
'http' => array(
'header' => "Authorization: Bearer 872ed5e72dfc7e4e0adaa7c663cab7d81415078fdbe4f486d085b718c93b3eb3")
)
);
// API URL for TG
$url = "http://api.tradegecko.com/variants";
// Get the JSON information from TG
$data = file_get_contents($url, false, $context);
// Decode that motherfucker
$json = json_decode($data);
$checking = array();
foreach ($json->variants as $row) {
$getsku = $row->sku;
$getid = $row->id;
$check_sku = $getsku." - ".$getid;
// show decoded results
//echo $check_sku."<br>";
$checking[] = $check_sku;
$string = "gini-gear";
// if the SKU matches the string, echo the product ID
//foreach ($check_sku as $product_info) {
if (strpos($string, $check_sku) !== FALSE) {
echo "The SKU was found, the ID is ".$getid;
return true;
}
//}
echo "The SKU was not found, try again";
return false;
// End of foreach $json->variants
}
?>
编辑2 ：仍然获得相同的回报 - ＆＃34;找不到SKU，再试一次＆＃34;
<?php
// Establish connection with TG
$context = stream_context_create(array(
'http' => array(
'header' => "Authorization: Bearer 872ed5e72dfc7e4e0adaa7c663cab7d81415078fdbe4f486d085b718c93b3eb3")
)
);
// API URL for TG
$url = "http://api.tradegecko.com/variants";
// Get the JSON information from TG
$data = file_get_contents($url, false, $context);
// Decode that motherfucker
$json = json_decode($data);
$checking = array();
foreach ($json->variants as $row) {
$getsku = $row->sku;
$getid = $row->id;
$check_sku = $getsku." - ".$getid;
// show decoded results
//echo $check_sku."<br>";
$checking[] = $check_sku;
$string = "gini-gear";
foreach ($checking as $id => $product_info) {
if (strpos($string, $product_info) !== FALSE) {
echo "The SKU was found, the ID is ".$id;
return true;
}
}
echo "The SKU was not found, try again";
return false;
// End of foreach $json->variants
}
?>
编辑3： var_dump提供以下内容。由于某种原因，有很多重复，这就是为什么它如此长（不能发布它太长），但看到它here
编辑4：我已经更改了strpos，但仍然遇到了同样的问题。以下是更正的strpos安排。
$string = "gini-gear";
foreach ($checking as $id => $product_info) {
if (strpos($product_info, $string) !== FALSE) {
echo "The SKU was found, the ID is ".$id;
return true;
}
}
答案 0 :(得分：0)
您需要在$checking循环中添加foreach数组。如果你想知道哪个ID匹配，你应该把它作为一个关联数组。
$checking = array();
foreach ($json->variants as $row) {
$getsku = $row->sku;
$getid = $row->id;
$check_sku = $getsku." - ".$getid;
// show decoded results
//echo $check_sku."<br>";
$checking[$getid] = $check_sku;
}
如果你在循环后这样做。 $check_sku只有最后一行的值，而不是每一行的所有值。
然后您的搜索循环应如下所示：
foreach ($checking as $id => $product_info) {
if (strpos($product_info, $string) !== FALSE) {
echo "The SKU was found, the ID is ".$id;
return true;
}
}
这是整个脚本，我已经测试过它并且有效：
<?php
// Establish connection with TG
$context = stream_context_create(array(
'http' => array(
'header' => "Authorization: Bearer 872ed5e72dfc7e4e0adaa7c663cab7d81415078fdbe4f486d085b718c93b3eb3")
)
);
// API URL for TG
$url = "http://api.tradegecko.com/variants";
// Get the JSON information from TG
$data = file_get_contents($url, false, $context);
// Decode it
$json = json_decode($data);
$checking = array();
foreach ($json->variants as $row) {
$getsku = $row->sku;
$getid = $row->id;
$check_sku = $getsku." - ".$getid;
// show decoded results
//echo $check_sku."<br>";
$checking[$getid] = $check_sku;
}
$string = "gini-gear";
foreach ($checking as $id => $product_info) {
if (strpos($product_info, $string) !== FALSE) {
echo "The SKU was found, the ID is ".$id;
return true;
}
}
echo "The SKU was not found, try again";
return false;
