    </month-name>
</TVchannel>

I have the above XML data file. I am trying to echo the title in the channel-name = "HR" section. So,the echo should be ' Welcome to HR-TV.

This is my php code for doing this

<?php
    $picture_container = simplexml_load_file('data.xml');
    echo $picture_container->[month-name[0]]->[channel-name[1]]->title;
?>

However, when I run this is get this error Parse error: syntax error, unexpected '[', expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' in C:\wamp64\www\POC - ITTV\logic.php on line 3

Kindly help

echo $picture_container->{'month-name'}[0]->{'channel-name'}[1]->title->__toString();

BTW, it should be {'channel-name'}[2] for output 'Welcome to HR-TV'.

There are a lot of errors in this :

1. month-name or channel-name are not constants. You can't use them as contants even they were constants you can't use "-" letter when declaring a constant or variable or any method or any function. ( PHP Interpreter understands it as minus operation. )

2. If you wanna access a generated property with -! or keys like these, you should use a syntax like this :

$something->{'keyword-name'}

So you can access your Simple XML Generated Properties like :

$picture_container->{'month-name'}[0]['channel_name'][1]->title;

Simply, try to remove -> operator when using square brackets wrapping. Similar as follows:

<?php
    $picture_container = simplexml_load_file('data.xml');
    echo $picture_container["month-name"][0]["channel-name"][1]->title;
?>
