I get a strange PHP error after updating my php version to 5.4.0-3.
I have this array:
Array
(
[host] => 127.0.0.1
[port] => 11211
)
When I try to access it like this I get strange warnings
print $memcachedConfig['host'];
print $memcachedConfig['port'];
Warning: Illegal string offset 'host' in ....
Warning: Illegal string offset 'port' in ...
I really don't want to just edit my php.ini and re-set the error level.
The error Illegal string offset 'whatever' in...
generally means: you're trying to use a string as a full array.
That is actually possible since strings are able to be treated as arrays of single characters in php. So you're thinking the $var is an array with a key, but it's just a string with standard numeric keys, for example:
$fruit_counts = array('apples'=>2, 'oranges'=>5, 'pears'=>0);
echo $fruit_counts['oranges']; // echoes 5
$fruit_counts = "an unexpected string assignment";
echo $fruit_counts['oranges']; // causes illegal string offset error

For those who come to this question trying to translate the vagueness of the error into something to do about it, as I was.
