Migration to PHP8

Question

I have code from old PHP. But when I tried to execute it by PHP 8.

The first code was:

PasteBin

I had error:

Fatal error: Array and string offset access syntax with curly braces is no longer supported in **** on line 550

On line:

for ($i = 0; $i < strlen($text); $i++) $res .= ord($text{$i}) . "-";

I changed it to:

for ($i = 0; $i < strlen($text); $i++) $res .= ord($text[$i]) . "-";

But I had another error:

Warning: Trying to access array offset on value of type bool in *** on line 76

On line:

$real = $row['sip'];

I have no idea - how to rewrite this string.
Can you help me?

Answer 1

the problem is that you are trying to access a boolean value as you do with an array.

i imagine that $row is the result of a query, and that query does not return any matching rows, so it's false.

just check if $row is false before you access it.

<?php
$row = false;
echo $row['test'];

this returns that warning.

as per your comment, it depends on what you wanna do.

if it exist return the values, if it doesn't?

if($row){
// if it contains something, do something with it
}else{
// do something else if it doesn't
}

i don't know what's the flow of your code, so I can't really help you, it's just a check to see if the $row variable is not false
