Probleme mit Auslesen der json-Datei

Hallo, nochmal,
da ich diesen Faden weder hochholen, noch meinen letzten Beitrag editieren darf, muss ich einen neuen aufmachen. @Moderator: ggf. den neuen Faden mit diesem hier zusammenlegen: https://www.lima-city.de/thread/externe-json-url-in-txt-datei-umwandeln
Es ist nämlich noch ein neues Problem aufgetaucht, was ich nicht verstehe. So treten bei strukturell eigentlich identischen json-Dateien unterschiedliche Ergebnisse zutage.
Während es hier funktioniert...
<?php ini_set('display_errors', 1); error_reporting(E_ALL); $url = 'https://www.mdr.de/XML/titellisten/jump_onair.json'; $contents = file_get_contents($url); $contents = utf8_encode($contents); $results = json_decode($contents); $song = $results->{'Songs'}->{'0'}->{'interpret'}." - ".$results->{'Songs'}->{'0'}->{'title'}; print( $song ); ?>
...kommt beim nachfolgenden Code die Fehlermeldung
Notice: Trying to get property of non-object in /home/webpages/lima-city/kurzmitteilungsservice/html/radioberlin/webradiotest/webradiopunktcc/ch/titel/fm1titel.php on line 9
<?php ini_set('display_errors', 1); error_reporting(E_ALL); $url = 'https://songinfo.fm1today.ch/FM1N/fm1n-current.json'; $contents = file_get_contents($url); $contents = utf8_encode($contents); $results = json_decode($contents); $song = $results->{'live'}->{'0'}->{'interpret'}." - ".$results->{'live'}->{'0'}->{'title'}; print( $song ); ?> -

Wie kommst du auf Faden, es ist ein Thema
Identisch vom Aufbau scheinen die jsons nicht zu sein:

Eventuell siehst du den Unterschied. [,"Songs":{"0":{"status":] - ["live":[{"title":"Down Under",]
Kann leider nicht den ganzen formatierten Code dir rein packen, sollte aber eigentlich so passen:
Dieser "Text" kann doch nun wirklich nicht als neuer Beitrag durchgehen, oder? Bitte kürze auf das Wesentliche, kopiere keine fremden Texte!

Hallo,
sollte so funktionieren, allerdings ungetestet...
$song = $results->{'live'}->{'interpret'}." - ".$results->{'live'}->{'title'}; -
OK, die Rohdaten geben tatsächlich...
{
"live": [
{
"title": "Smooth",
}
]
}
...aus. Die json wirft allerdings widersprüchlicherweise...
live
0
title "Smooth"
...aus.
@fits-radio: Der Verzicht auf die "0" führt zur gleichen Fehlermeldung. -
<?php ini_set('display_errors', 1); error_reporting(E_ALL); $url = 'https://songinfo.fm1today.ch/FM1N/fm1n-current.json'; $contents = file_get_contents($url); $contents = stripslashes(trim($contents)); if (substr($contents, 0, 3) == "\xef\xbb\xbf") { $contents = substr($contents, 3); } $contents = utf8_encode($contents); $results = json_decode($contents); $song = $results->{'live'}[0]->{'interpret'}." - ".$results->{'live'}[0]->{'title'}; print( $song ); ?>
Bisschen probiert, die Datei wird (manchmal) mit BOM gespeichert, welches (wenn vorhanden) in dem neuen Code entfernt wird. Desweiteren ist {'live'} ein Array.

OK, danke, die Titelanzeige funktioniert jetzt. Auf eine BOM-Codierung wäre ich nicht gekommen.
