How can I search , replace + increment in a html file?

Question

I have 1,000 html pages. And a js script.

In the java code in the page I have somewhere "$ item_id = 1".

In every page I must change the id. I mean, in page_2.html I must have "$ item_id = 2" in the page_3.html I must have "$ item_id = 3" ... etc

I check more TextCrawlers softwares, but it offers me only search and replace, without incremental option.

Any ideas?

The Solution. First, replace in all your files all "$ item_id = 1", "$ item_id = 2" .. etc, with "$ item_id = wxyz" Then run the php script below in localhost, in the folder you keep the html files. You can name it 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';
}
