如何將此字符串分解爲這樣的數組？

Question

我試圖打破這種字符串，

AFRIKAANS = af 
ALBANIAN = sq 
AMHARIC = am 
ARABIC = ar 
ARMENIAN = hy 
AZERBAIJANI = az 
BASQUE = eu 
BELARUSIAN = be 
BENGALI = bn 
BIHARI = bh 
BULGARIAN = bg 
BURMESE = my 
CATALAN = ca 
CHEROKEE = chr 
CHINESE = zh 

進入這樣

$lang_codes['chinese'] = "zh"; 

數組所以語言的名稱是關鍵，和值是語言代碼。這非常簡單，但我無法理解它。我已經採取了從編程制動，時間過長，很明顯......

我試過在\n爆炸然後用foreach，在=再次爆炸，但我似乎無法拼湊一起就是我想要的。

Answer 1

我試過在\爆炸N，然後使用foreach，再次在爆炸「=」

我認爲這是完全正確的做法。

$lines = explode("\n", $langs); 
$lang_codes = array(); 

foreach ($lines as $line) { 
    list ($lang, $code) = explode(" = ", $line, 2); 
    $lang_codes[$lang] = $code; 
}

如果你想在語言使用小寫字母，因爲在你的例子（$lang_codes['chinese']），您將需要調用strtolower：

$lang_codes[strtolower($lang)] = $code;

查看PHP手冊欲瞭解更多關於這些功能：

• list
• explode

Answer 2

MAYB你shold做：

$array = explode("\n" , $string); 
$finalArray =array(); 
$foreach ($array as $value){ 
     $array2 = explode(' = ', $value); 
     $finalArray[$array2[1]] = $array2[0]; 

} 

Answer 3

<?php 
$str ="AFRIKAANS = af 
ALBANIAN = sq 
AMHARIC = am 
ARABIC = ar 
ARMENIAN = hy 
AZERBAIJANI = az 
BASQUE = eu 
BELARUSIAN = be 
BENGALI = bn 
BIHARI = bh 
BULGARIAN = bg 
BURMESE = my 
CATALAN = ca 
CHEROKEE = chr 
CHINESE = zh"; 

$arr = explode("\n", $str); 
$lang_mapped = array(); 

foreach ($arr as $line) { 
    list ($lang, $code) = explode(" = ", $line, 2); 
    $lang_mapped[$lang] = $code; 
} 
$arr = explode("\n", $str); 
echo "<pre>"; 
print_r($lang_mapped); 
echo "</pre>"; 
?> 

Answer 4

雖然爆炸的答案是技術上是正確的，我立刻想到，你試圖解析INI文件。這是更簡單的方法，完全符合你的要求。

<?php 
$string = "AFRIKAANS = af 
ALBANIAN = sq 
AMHARIC = am 
ARABIC = ar 
ARMENIAN = hy 
AZERBAIJANI = az 
BASQUE = eu 
BELARUSIAN = be 
BENGALI = bn 
BIHARI = bh 
BULGARIAN = bg 
BURMESE = my 
CATALAN = ca 
CHEROKEE = chr 
CHINESE = zh"; 

$array = array_change_key_case(parse_ini_string($string)); 

echo $array['chinese'];
