Array keys encoded using http_build_query ()
Encoding a url array with http_build_query()
causes strange behavior when the array key is also html-char code.
For example:
return http_build_query([
'id' = > ['my', 'data', 'here'], // no problem
'class' = > ['my', 'data', 'here'], // no problem
'yen' = > ['my', 'data', 'here'], // ¥ html car is ¥
'parameter' = > ['my', 'data', 'here'], // ¶ html char is ¶
]);
and the encoded result:
id[0]=my&id[1]=data&id[2]=here&class[0]=my&class[1]=data&class[2]=here¥[0]=my¥[1]=data¥[2]=here¶meter[0]=my¶meter[1]=data¶meter[2]=here
What's going on here, it's possible, perhaps, that I can't use the word parameter as the array key.

If you look at the HTML output source you will see
id% 5B0% 5D = mine & id% 5B1% 5D = data & id% 5B2% 5D = here & class% 5B0% 5D = mine & class% 5B1% 5D = data & class% 5B2% 5D = here and amplifier; yen% 5B0% 5D = my & yen% 5B1% 5D = data & yen% 5B2% 5D = here & parameter% 5B0% 5D = mine & parameter% 5B1% 5D = data & parameter% 5B2% 5D = here
It is right. When rendered, only the browser interprets malformed objects such ¥
as ¥. There is nothing to worry about on the server side.
