I have code from old PHP. But when I tried to execute it by PHP 8.
The first code was:
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?
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
