Apostrophe and Javascript / PHP

Question

Right now I have this for my javascript code

'title': '<?=$name?>',

The thing is, occasionally $name will have an apostrophe in it, and can have the code look something like this

'title': 'Bon Jovi It's My Life - Bon Jovi',

which essentially screws up the javascript.

Would I just do a mysql_real_escape_string on the $name? Wouldn't that leave slashes in the title when I go to use it?

Thanks

Answer 1

<script type="text/javascript">
    var myJson = {
       title: '<?php echo addslashes($somePHPVar) ?>'
    };
</script>

addslashes is the key. See the docs.

Answer 2

use str_replace() before send the string to javascript

str_replace($name, ' ', '-');

Answer 3

Use json_encode(). Never build JSON using string functions.
