Hi everyone,
I am struggling with regular expression trying to match strings
delimited by double quotes, but taking into consideration that \" is not
a string ending character.
STFW for the concept "look behind assertion" - that is what you need to
differentiate between an escaped double-quote and the delimiting double quote.
-------8<---------------------------------------------------------------
-
$in = 'this is a string : "Hi everyone my name is \"Mathieu\"!" Here is
a second string : "PHP is just perfect"';
// pattern for catching strings between "
$pattern = '#"([^"]*)"#';
// surround matching string with HTML span code to highlight
$replacement = '<b>"${1}"</b>';
// perform the reg exp replacement
$out = preg_replace($pattern, $replacement, $in);

$out contains :
this is a string : <b>"Hi everyone my name is \"</b>Mathieu\<b>"!"</b>
Here is a second string : <b>"PHP is just perfect"</b>
This behaviour is normal considering my pattern (anything between two "
that is not a ").
But I don't know how to get this :
this is a string : <b>"Hi everyone my name is \"Mathieu\"!"</b> Here is
a second string : <b>"PHP is just perfect"</b>
I would like my pattern to express : Anything between two " that is not
a " except if it is escaped.
Thanks for reading me, any help in return is welcome !
