我想从上面的数组中搜索wrod Word＆＃34;摩托车＆＃34;并获得iri http路径。

任何帮助??

Answer 1

你没有说你是想要它们还是仅仅是第一个。

$val = "Motorcycle";


// only first
$ind = array_search ( $val, $arr ["product"], true );
if ($ind >= 0) {
    echo  $arr ["iri"] [$ind] . "<br>";
}

echo "<hr>" ;

// all values
foreach ( array_keys ( $arr ["product"], $val, true ) as $ind ) {
    echo $arr ["iri"] [$ind] . "<br>";
}

Answer 2

我已经看过你提供的array，并想指出一些事实：

• "Motorcycle"位于"product"
内
• "Motorcycle"重复，因此我们需要能够决定我们之前搜索的"Motorcycle"
• "Motorcycle"在多个位置以不区分大小写的方式显示为substring

首先，让我们实现一个函数，该函数将找到iri的相应string。请注意，我们需要确定我们是否在搜索更多iri元素（如果它们是重复的）以及我们是否希望它区分大小写：

function getIri($input, $str, $duplicates = false, $caseInsensitive = false) {
    $output = array();
    foreach ($input["iri"] as $element) {
        if (($caseInsensitive && (stripos($element, $str) >= 0)) ||
           (strpos($element, $str) >= 0)) {
               $output[]=$element;
               if (!$duplicates) {
                   return $output;
               }
        }
    }
    return $output;
}

然后，您需要对product执行相同的操作：

function getPreviousProductOf($input, $str, $duplicates = false, $caseInsensitive = false, $substring = false) {
    $output = array();
    //We start from 1, as the 0'th element does not have a previous
    for ($index = 1; $index < count($input["product"]); $index++) {
        if (($substring && $caseInsensitive && (stripos($input["product"][$index], $str) >= 0)) ||
           ($substring && !$caseInsensitive && (strpos($input["product"][$index], $str) >= 0)) ||
           (!$substring && $caseInsensitive && (strcasecmp($input["product"][$index], $str) === 0)) ||
           (!$substring && !$caseInsensitive && ($input["product"][$index] === $str))) {
            $output = array_merge($output, getIri($input, $input["product"][$index]), $duplicate, $caseInsensitive);
            if (!$duplicate) {
                return $output;
            }
        }
    }
    return $output;
}

最后，您需要调用第二个function，如下所示：

var $result = getPreviousProductOf($input, "Motorcycle");
