Hello,

Since phpdocx 12.5 (https://www.phpdocx.com/news/post/phpdocx-v12-5-release-notes/224), searchAndReplace allows using strings and arrays to replace contents:

DocxUtilities: searchAndReplace, searchAndRemove and searchAndHighlight methods allow using arrays (Advanced and Premium licenses).

From the API documentation page:

search

The string of text or array that you want to replace.

replace

The string of text or array that you want to include.

Please check the following included in the package (DocxUtilities/searchAndReplace/sample_2.php):

$docx = new DocxUtilities();

$options = array(
    'document' => true,
    'endnotes' => true,
    'comments' => true,
    'headersAndFooters' => true,
    'footnotes' => true,
);

$searchTerms = array(
    'data',
    'Another',
    'Some',
    'More',
    'comment',
);
$replaceTerms = array(
    'required data',
    'Other',
    'SOME',
    'MORE',
    'my comment',
);
$docx->searchAndReplace('../../files/second.docx', 'example_searchAndReplace_2.docx', $searchTerms, $replaceTerms, $options);

Using previous versions of phpdocx you need to call searchAndReplace as many times as needed, generating a new file for each string to be replaced.

This method supports plain texts, but not regex, so your approach is correct to get dynamically the content to be replaced.

Regards.
