$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); 

Answer 1

preg_replace溶液：

// 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（准备好被保存到文件中）：

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