add Multiple classes in a PHP echo statement

Question

Hi I am trying to add more than one class whilst echoing some html but it Just does not seem to work. the PHP looks like the following:

echo
"<div class="."alert alert-success"." role="."alert".">
        <strong>Well done!</strong> You successfully read this important alert message.
</div>";

the output looks like this (captured using dev tools on chrome):

<div class="alert" alert-success="" role="alert">
        <strong>Well done!</strong> You successfully read this important alert message.
</div>

It has autofilled the ="" on the alert-success but it looks like this officially

<div class="alert" alert-success role="alert">
        <strong>Well done!</strong> You successfully read this important alert message.
</div>

For some reason the alert-success class appears to be put in after the brackets. I have tried moving around the " but it remains in the same place. is there something simple I am missing.

read this: Strings

The real output is :

<div class=alert alert-success role=alert>
        <strong>Well done!</strong> You successfully read this important alert message.
</div>

The reason to this is simple : strings in PHP are enclosed by double quotes, and in your code you never put double quotes in the string : you use them to close the string.

To use a double quote in a PHP string enclosed by double quotes, you need to escape the character, by adding a backslash before it :

echo
"<div class=\"alert alert-success\" role=\"alert\">
        <strong>Well done!</strong> You successfully read this important alert message.
</div>";

Try with -

echo
"<div class='alert alert-success' role='alert'>
        <strong>Well done!</strong> You successfully read this important alert message.
</div>";

The problem is double code and single code so that is wont work. If you want to use double code us backslash.

class=\"alert alert-success\" role=\"alert\"

This is run successfully thanks.

"Well done! You successfully read this important alert message";
