I am using PHPExcel to extract data from my database onto an organized Excel sheet. Everything is working great except for one thing. My database entries can sometimes contain HTML markups like <strong></strong>, <BR>, <p></p> etc ... So I managed to get this PHP line working, this is working great to replace my <BR> markups to a space.

$data = str_replace("<br />", "n", $data);         
$data = str_replace("<br/>", "n", $data);          
$data = str_replace("<br>", "n", $data);

However when I try doing the following it does nothing. I was expecting that it would bold the text.

$data = str_replace("<strong>", '&B', $data);

I read on these forums that its best to use preg_replace and setup an array for all the HTML markups I need replaced. For the life of me I can't understand how to use preg_replace. Would someone please give me some advise what is the best way to replace markups such as <strong> and </strong> to bold when it exports, this would be very much appreciated.



'&B' will only set bold text for printed page headers and footers, as described in the section of the documentation entitled Setting the print header and footer of a worksheet

Formatting the content of a cell is described in the section of the documentation entitled Formatting cells, something like:


or (if your content contains actual markup) using Rich Text objects if you only want to set part of the text to bold.

$objRichText = new PHPExcel_RichText();
$objRichText->createText('This text is ');

$objBoldTextRun = $objRichText->createTextRun('bold');

but you will need to parse your markup to convert it to a Rich Text object

<form name="add" method="post">
     <select name="age">
        <option value="1_sre">23</option>
        <option value="2_sam">24</option>
        <option value="5_john">25</option>
     <input type="submit" name="submit"/>

You will have the selected value in $_POST['age'], e.g. 1_sre. Then you will be able to split the value and get the 'stud_name'.

$stud = explode("_",$_POST['age']);
$stud_id = $stud[0];
$stud_name = $stud[1];

The usual workflow:

  1. Provide a Javascript rich-text editor for your users such as TinyMCE:
  2. Grab the source generated by the RTE and filter it through HTML Purifier before saving to the database.
  3. Escape the existing HTML: <div id="myHtml" style="display: none"><?php echo htmlentities($html); ?></div>
  4. Re-populate the RTE via Javascript - in the case of TinyMCE as follows: tinyMCE.activeEditor.setContent($('#myHtml').html());

You can also load the HTML content via AJAX.

Eventually solved it with the help of TiMESPLiNTER (give him the credit!), didn't know $1 didn't get brought along and that you have to call a variable $matches in the callback function and get $matches[1] instead of $1.

$counter = 1;

function parse(){
    function cb($matches){
        global $counter;

        return '<span class="b">'. $this->counter .'. ' . $matches[1] . '</span>';

    $string = preg_replace_callback("_(.*?)_si", 'cb', $string);

Use the vectorised str method replace:

In [30]:

df['range'] = df['range'].str.replace(',','-')
0    (2-30)
1  (50-290)


So if we look at what you tried and why it didn't work:


from the docs we see this desc:

str or regex: str: string exactly matching to_replace will be replaced with value

So because the str values do not match, no replacement occurs, compare with the following:

In [43]:

df = pd.DataFrame({'range':['(2,30)',',']})
df['range'].replace(',','-', inplace=True)
0    (2,30)
1         -
Name: range, dtype: object

here we get an exact match on the second row and the replacement occurs.
