我有 1,000 个 html 页面。还有一个js脚本。
在页面的java代码中我有“$ item_id = 1”。
在每个页面中我都必须更改 id。我的意思是，在 page_2.html 我必须有 "$ item_id = 2" 在 page_3.html 我必须有 "$ item_id = 3" ... 等等
我检查了更多 TextCrawlers 软件，但它只为我提供搜索和替换，没有增量选项。
有什么想法吗？
解决方案。首先，将所有文件中的所有
"$ item_id = 1""$ item_id = 2""$ item_id = wxyz"replace_increment.php<?php
$to_be_replaced = 'wxyz'; // exactly what it wants replaced
$nr_start = 1; // from which no start counting
$path_files = getcwd();
// echo $path_files;
$excluded_files = array(
'.htaccess',
'robots.txt',
'.ftpquota',
'search.html',
'replace_increment.php',
);
$file_list = get_list_dir($path_files, false, 'file', true, $excluded_files);
if ( is_array($file_list) && count($file_list)) {
// sort list files
natsort($file_list);
//echo '<pre>'.var_export($file_list,1).'</pre>';
foreach($file_list as $file) {
$original_content = file_get_contents($file);
// Search the file for the replacement piece
if ( stristr($original_content, $to_be_replaced) ) {
// if found, replaces
$content_modified = str_replace($to_be_replaced, $nr_start, $original_content);
// remove the blank lines
$content_modified = str_replace("\n\n\n\n", "\n\n", $content_modified);
// save the file contents back
$is_saved = file_put_contents($file, $content_modified);
if ( ! $is_saved ) {
die('Error: Unable to modify the file '.$file.'. I stayed at number '.$nr_start);
}
$nr_start++;
}
}
echo 'They were checked '.count($file_list).' files and the last number is '.($nr_start - 1);
} else {
echo 'Files Not found, check the file path';
}

您可以使用硬编码或动态的基本思想来制作一个小程序。 因此，您定义了多个页面（示例适用于相同名称）。
您采用 for 循环并像（在 C# 中）一样使用它：
using System.IO;
using System.Text.RegularExpressions;
for (int i = 1; i <= numberOfPages; i++)
{
File.WriteAllText("Path\\page_" + i + ".html", Regex.Replace(File.ReadAllText("Path\\page_" + i + ".html"), @"\$ item_id = 1", "$ item_id = " + i));
}
如果您有不同的文件名，则需要使用正则表达式来获取正确的编号，并使用 for-each 循环遍历包含文件名的列表。
