我想從上面陣列字「摩托車」搜索wrod並獲得IRI HTTP路徑。PHP數組搜索值

任何幫助？

你沒有說如果你想要他們全部或只是第一個。

$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>"; 
}

我已經採取了看看array你給了，並想指出幾個事實：

"Motorcycle"裏面"product"
"Motorcycle"是重複的，所以我們需要能夠決定哪個"Motorcycle"的以前我們正在搜索
"Motorcycle"在幾個位置以不區分大小寫的方式顯示爲substring s

因此，首先讓我們實現一個函數，該函數將找到string的相應iri。請注意，我們需要決定他們是否重複我們是否更多iri元素搜索，我們是否希望它是區分大小寫的：

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; 
}

然後，你需要做同樣的product：

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; 
}

最後，你需要調用第二function，像這樣：

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