I have a json string which contains some html and it's attrubutes. I'm trying to to escape or replace double quotes with single quotes in this string. my code works with some html attributes but not with all.

My example:

$json='{"en":"<b class="test" size="5" >Description</b>"}';
$json=preg_replace('/([^:,{])"([^:,}])/', "$1".'\''."$2",$json);
echo htmlspecialchars($json);
//ouput: {"en":"<b class='test' size='5" >Description</b>"}


Needed result:

{"en":"<b class='test' size='5' >Description</b>"}
preg-replace php json

I hope this works as expected ([^{,:])"(?![},:])

$json='{"en":"<b class="test" size="5" >Description</b>"}';
$json=preg_replace('/([^{,:])"(?![},:])/', "$1".'\''."$2",$json);

Results in

{"en":"<b class='test' size='5' >Description</b>"}

Try this one : str_replace('"', "'",$json);

$json='{"en":"<b class="test" size="5" >Description</b>"}';
$json=str_replace('"', "'",$json);
echo htmlspecialchars($json);

Output will : {'en':'<b class='test' size='5' >Description</b>'}
