搜索通過JSON陣列匹配關鍵

Question

我試着通過JSON數組搜索和查找包含字獎牌，即所有的鍵...

• medalsActivityCompleteHighestScoreWinning
• medalsActivityCompleteVictoryBlowout
• medalsKillHeadshot
• medalsKillMulti2
• medalsKillSpree1
medalsKillSpree2
• medalsWinningScore
• medalsWeaponPulseRifleKillSpree
• medalsPaybackKill
• medalsAvenger

IVE試圖...

$x = '0'; 
foreach ($json['Response']['data']['entries']['0'] as $extended) { 
    $valueName[] = $extended['values']; 

    if (strpos($valueName[$x], 'medals') !== false) { 
     echo $valueName[$x]; 
    } 

    $x++; 
} 

這是陣列

Answer 1

它應該做的伎倆：

foreach ($json['Response']['data']['entries'][0]['extended']['values'] as $key => $value) { 
    if (false !== strpos($key, 'medals')) { 
     echo $value.PHP_EOL; 
    } 
} 

或者，你可以使用array_filter：

var_dump(array_filter($json['Response']['data']['entries'][0]['extended']['values'], function ($k, $v) { 
    return false !== strpos($k, 'medals'); 
}, ARRAY_FILTER_USE_BOTH));
