PHP escape JSON string saved in a var

Question

So I have some JSON string that I write to a file, and parse it afterwards, for an export/import tool the problem is on import when I try to parse the file using json_decode it dies because of the caracter escaping.

Here I have an example so you can understand better:

enter image description here

When I write the content I do some basic file_put and json_encode

eg:

$current .= "\n\n\n".'$pagzDynamicPages = \''.json_encode($pagzDynamicPagesData).'\';';

So is there a way to escape this type of strings?

Maybe you could use; mysql_real_escape_string or the mysqli version of it? — Tosfera

Try

$current .= "\n\n\n".
    '$pagzDynamicPages = '.
    var_export(json_encode($pagzDynamicPagesData), TRUE).
    ';';

The function var_export() produces a valid PHP expression for the provided data structure.

I want to offer the file to be available for download...so var_export won't work in this case... I tried... and it displays the content instead of offering it for download

Check its documentation. If you pass TRUE as the second parameter it won't output anything but return the PHP code it produces.

I misplaced a closing parenthesis on the original version of the code. Fixed now and formatted to code to be more readable.

You need to escape it properly. Best way probably is heredoc: http://php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc

You can fix the JSON with str_replace:

$pagzDynamicPagesData = str_replace("'", "\'", $pagzDynamicPages);
