Question

How can I convert all single quotes to double quotes in all HTML tags only? Is there an easier way to do it?
Thanks 🙂

For example:
How can I convert this string (actual data from my work):

<TEXTFORMAT LEADING='2'><P ALIGN='LEFT'><FONT FACE='Verdana' style="font-size:10' COLOR='#0B333C'>My name's Mark</FONT></P></TEXTFORMAT>

To this:

<TEXTFORMAT LEADING="2"><P ALIGN="LEFT"><FONT FACE="Verdana" style="font-size:10" COLOR="#0B333C">My name's Mark</FONT></P></TEXTFORMAT>

Answer 1

If you don’t care about the JavaScript and CSS issues mentioned elsewhere, try this:

$text = "<TEXTFORMAT LEADING='2'><P ALIGN='LEFT'><FONT FACE='Verdana' style='font-size:10' COLOR='#0B333C'>My name's Mark</FONT></P></TEXTFORMAT>";
echo preg_replace('/<([^<>]+)>/e', '"<" . str_replace("\\\\\'", \'"\', "$1") . ">"', $text);
