找出每个单词在db中重复多少次

Question

我正在使用 drupal 来管理我的内容。我想搜索我所有的内容标题和正文，并找出每个单词在整个内容中重复了多少次。

可能是通过sql查询，但我没有使用sql的经验。

有什么想法吗？

Answer 1

此代码在 ANY 内容类型的正文字段和 ALL 字段中搜索特定字符串。您可以通过命令行运行它。假设您将其保存为“fieldsearch.php”，然后您可以将其运行为：

php fieldsearch.php "myStringForWhichToSearch"

您需要填写您的连接数据和数据库名称。它输出匹配节点的数组，但您可以将该输出格式化为您想要的任何内容（我推荐 csv）。

<?php


//Set Parameters here
$env = "dev"; // Options [dev|prod] - Defaults to dev

$prodConnection = array(
                        "host" => "",
                        "user" => "",
                        "pass" => ""
                        );


$devConnection = array(
                        "host" => "",
                        "user" => "",
                        "pass" => ""
                        );

//Use the selected env settings
if($env == "prod"){
  $connection = $prodConnection;
} else {
  $connection = $devConnection;
}



function getTables($con, $database){
  //Get the set of field tables
  $sql = "SHOW TABLES FROM $database";
  $result = mysqli_query($con, $sql);

  if (!$result) {
      echo "DB Error, could not list tables\n";
      echo 'MySQL Error: ' . mysql_error();
      exit;
  }

  $tables = array();
  while ($row = mysqli_fetch_row($result)) {
      $tables[] = $row[0];

  mysqli_free_result($result);

  return $tables;

function getFieldTables($con,$database){
  $allTables = getTables($con, $database);

  $fieldTables = array();
  foreach($allTables as $key => $table){

    if( isFieldTable($table) ){
      $fieldTables[] = $table;
    }
  }

  //add the common tables
  $fieldTables[] = "field_data_body";
  $fieldTables[] = "field_data_comment_body";

  return $fieldTables;
}

function isFieldTable($table){
  //echo $table . "\n";
  if( stripos($table, "field_data_field") !== FALSE){
    return TRUE;
  }
}

//Set the search term here:

  $searchString = $argv[1];

  $outArray = array();

  $fieldTables = getFieldTables($con, $databaseName);

  //Query each field tables data for the string in question
  foreach($fieldTables as $key => $table){
