Question

我想在多维数组中搜索并替换.txt文件中文本的值

Advertisement and Printing -> Advertising Materials
Health Care -> Medical Laboratory
Business Services -> ISO Consultants
Packaging -> Bindings and Laminations

依旧......

.txt文件内容

$fileContents = file_get_contents("theFile.txt");
$search = $array;
$replace = array(); // Not sure about the replace
$newContents = str_replace($search, $replace, $fileContents);
$handle = fopen("theFile.txt","w");
fwrite($handle, $newContents);
fclose($handle);

例如，在上面的例子中，我希望用数组值替换字符串 广告和印刷 - ＆gt;广告材料至 6 - ＆gt; 8

a,b,c -> a, ab, abc ...

preg_replace解决方案：

// sample array (extended)
$arr = [
    ['Advertisement and Printing' => 6], ['Health Care' => 1],
    ['Medical Laboratory' => 3], ['Advertising Materials' => 8],
    ['Business Services' => 4], ['ISO Consultants' => 12],
    ['Packaging' => 10], ['Bindings and Laminations' => 14]
];

$lines = file_get_contents('theFile.txt');
$result = "";

foreach ($arr as $key => $val) {
    list($k, $v) = each($val);
    $lines = preg_replace("/(-> )$k|^$k/m", '${1}'.$v, $lines);
}

print_r($lines);

输出（准备保存到文件中）：

6 -> 8
1 -> 3
4 -> 12
10 -> 14
