Gedeelte array printen zodat ik deze later kan opmaken
Het is mij na een tijdje gelukt om een api request te maken naar een api die ik wil gebruiken in een projectje. Ik heb op dit forum gelezen dat wanneer ik deze afdruk met een print_r command ik de arrays op menselijk interpreteerbare wijze kan bekijken. Dit is ook gelukt. Mijn vraag nu is, hoe kan ik uit deze array stukjes data selecteren?
Dit is de code die ik op het moment gebruik:
Code (php)
1
2
3
4
5
6
7
8
9
10
11
12

$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo '<div class="searchresult">';
$decoded = json_decode($response);
print_r($decoded);
echo '</div>';
}
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo '<div class="searchresult">';
$decoded = json_decode($response);
print_r($decoded);
echo '</div>';
}
De output die ik krijg is als volgt:
Code (php)

Dit gaat dan door tot array [9]. Dus 10 arrays in totaal.
Ik wil hier dan de totalCount en relatedSearch van printen, en voor iedere volgende array de title, url en description. Ik geloof dat ik voor het laatste een (foreach?) loop moet maken die alle arrays stuk voor stuk af gaat. Ik kan hier alleen niets over vinden als ik dit opzoek (waarschijnlijk zoek ik verkeerd).
Ik hoop dat iemand mij de juiste richting in kan sturen!
Met vriendelijke groet,
Joris
En verder voor 'relatedSearch' inderdaad een foreach. Zie ook https://www.w3schools.com/php/php_looping_foreach.asp
Horen de keys van 'relatedSearch' en 'value' bij elkaar?

Ik geloof dat de keys van relatedSearch en value niet bij elkaar horen, maar volgensmij vallen de andere arrays (de resultaten zelf) wel onder value horen.
Toevoeging op 18/02/2021 14:20:36:
Mijn foreach loop lijkt niet helemaal te werken. Ik ben vrij zeker dat ik iets verkeerd doe maar zie niet helemaal in wat ik mis doe. Het printen van de totalCount lukt wel, maar ik weet niet hoe ik de titel/url/description uit de arrays moet halen.
Dit is wat ik nu heb:
Code (php)
1
2
3
2
3
foreach ($decoded as $result) {
echo "$result->title <br>";
}
echo "$result->title <br>";
}
Probeer dit eens:
Code (php)
1
2
3
2
3
foreach ($decoded['value'] as $result) {
echo "$result->title <br>";
}
echo "$result->title <br>";
}
Of als het root-object een stdClass is:
Code (php)
1
2
3
2
3
foreach ($decoded->value as $result) {
echo "$result->title <br>";
}
echo "$result->title <br>";
}
Goed lezen is ook voor mij soms moeilijk, het is een stdClass.
