Question

我有一个像这样的变量（在原始列表中没有空格）： http://www.iso.org/iso/list-en1-semic-3.txt

$country ="
ÅLAND ISLANDS;AX
ALBANIA;AL
ALGERIA;DZ
";

（以相同的顺序继续）

我喜欢把它放在这样的数组中：

array:  [Åland Islands] ==> AX
        [Albania] ==> AL
        [Algeria] ==> DZ

我尝试使用php爆炸，但这不起作用，我的基本知识是正确的。谁可以帮忙？

 print_r(explode(';', $country));

Answer 1

这会让你到达目的地：

$output = array();
// break it line-by-line
$lines = explode('\n', $country);
// iterate through the lines.
foreach( $lines as $line )
{ 
    // just make sure that the line's whitespace is cleared away
    $line = trim( $line );
    if( $line ) 
    {
        // break the line at the semi-colon
        $pieces = explode( ";", $line );
        // the first piece now serves as the index. 
        // The second piece as the value.
        $output[ $pieces[ 0 ] ] = $pieces[ 1 ];
    }
}

Answer 2

$result = array();
$lines  = explode(PHP_EOL, $country);

foreach ($lines as $line) {
    $line = explode(';', $line);
    $result[array_shift($line)] = array_shift($line);
}

Answer 3

$a = explode("\n", $country);
$result = array();
foreach($a as $line) {
    list($x,$y) = explode(";", $line);
    $result[$x] = $y;
}

注意：从$ country中删除多余的空行或检查空行。
