Question

I have to replace all HTML markup in a text with BB Codes, and I am struggling with replacing the inline CSS styled elements.

HTML:

<span style="font-family: arial;">Arial</span>
<span style="font-size: 7px;">small text</span>
<span style="color: skyblue;">Blue Text</span>
<div align="center">centered text</div>

Should get replaced by the following:
BB Code:

[FONT=arial]Arial[/FONT]
[SIZE=7]small text[/SIZE]
[COLOR=skyblue]Blue Text[/COLOR]
[CENTER]centered text[/CENTER]

whereas the font families, color codes, and size values can differ.

Non working starting point:

$text = preg_replace('#<span style="color: (.*?);">(.*?)</span>#siU', '[color=$1]$2[/color]', $text);

Answer 1

How about

$text = preg_replace('/<span style="color: (.*?);">(.*?)<\/span>/siU', '[color=$1]$2[/color]', $text);

I just replaced the # with / and it’s working for me.
As for the other replacements:

/<span style="font-size: (.*?)px;">(.*?)<\/span>/
[size=$1]$2[/size]

/<span style="font-family: (.*?);">(.*?)<\/span>/
[font=$1]$2[/font]

/<div align="(.*?)">(.*?)<\/div>/
[$1]$2[/$1]

UPDATE
Fiddled it: phpfiddle.org/main/code/zqu-bgs
(end escaped the / of the closing tags)
