I came to the conclusion after about 3.5hrs of experimenting. Newbies may test too.

Thanks for the code on how to echo things. But that's not what I really was trying to do. I was experimenting and trying to figure how php does things. I came to this following conclusion. I opened this thread to learn if my conclusion is spot-on or not and so I'd appreciate if you let me know if I am spot on or not.
**CONCLUSION:
If array (full) is turned into variable $ then offset must be inside the same bracket.
If array (full) is NOT turned into variable $ then it must be quoted. And, offset must be in a separate bracket.**
If you are confused then check my op and my previous post that shows my experiment.@ginerjm
Do you mind letting me know about my conclusion above ?
What do you think ? Percentage-wise, how spot-on was I ?I have no interest in this topic. Learn from that. If you have a question post the question and the code that is giving you that question. Stop posting these theoretical nonsensical things. We're here to help, not necessarily to teach. You will learn from the answers we provide to your genuine problems. Our time is wasted otherwise. @ginerjm#1637450
I did some experiments. I came to a conclusion from my code research. Asked you seniors to let me know if my conclusion was correct or not. If you say, it is correct, then I learnt something and stick to what I learnt. Else, I quit learning my findings. I empty my cup and pour out the bad tea.
That's all.
What's the harm in that ?
Is My Array Conclusions True ?
Hi,
Is my conclusion correct ?
CONCLUSION:
1. If array (full) is turned into variable $ then offset must be inside the same bracket.2. If array (full) is NOT turned into variable $ then it must be quoted. And, offset must be in a separate bracket.
[code]
<?php
$string = ‘full[]=title&title=mrs&full[]=first_name&first_name=iris&full[]=surname&surname=alison’;
parse_str($string);
echo $arr[‘full'[0]]; //Outputs: Notice: Undefined index: f in ..
echo $arr[‘full[0]’]; //Outputs: Notice: Undefined index: full[0] in ..
echo $arr[‘full’][0]; //Outputs: title. Outputs: Array Key.
echo $arr[“full”[0]]; //Outputs: Notice: Undefined index: f in ..
echo $arr[“full[0]”]; //Outputs: Notice: Undefined index: full[0] in ..
echo $arr[“full”][0]; //Outputs: title. Outputs: Array Key.
echo $arr[$full][0]; //Outputs: Warning: Illegal offset type in ..
echo $arr[$full[0]]; //Outputs: mrs. Outputs: Array Value.
