我有简单的文字字符串,它看起来像那样:
30143*1,30144*2,30145*3,30146*5,30147*5
我必须使用以下结构将此文本字符串转换为数组:
Array ( [0] => Array ( [product] => 30143 [qty] => 1 ) [1] => Array ( [product] => 30144 [qty] => 2 ) [2] => Array ( [product] => 30145 [qty] => 3 ) [3] => Array ( [product] => 30146 [qty] => 4 ) [4] => Array ( [product] => 30147 [qty] => 5 ) )
是否有可能,如果是这样的话?
我发现了这个:
$myString = "9,admin@example.com,8";
$myArray = explode(',', $myString);
print_r($myArray);
但这只是创建没有键的数组,例如,无法使用qty
获取*
键。
提前致谢!

你走了。您需要遍历所有30143*1
项。 array_map
为你做这份工作。
function getPieces($val) {
$pieces = explode('*', $val);
return ['product' => $pieces[0], 'qty' => $pieces[1]];
}
$str = '30143*1,30144*2,30145*3,30146*5,30147*5';
$result = array_map('getPieces', explode(',', $str));
var_dump($result);
<强>输出:强>
array (size=5)
0 =>
array (size=2)
'product' => string '30143' (length=5)
'qty' => string '1' (length=1)
1 =>
array (size=2)
'product' => string '30144' (length=5)
'qty' => string '2' (length=1)

'qty' => string '5' (length=1)

这可能是以下方式之一:
$string = '30143*1,30144*2,30145*3,30146*5,30147*5';
$products = explode(',',$string);
$result = array();
foreach ($products as $productAndQuantity) {
$result[] = array_combine(array('product', 'qty'), explode('*', $productAndQuantity));
}
var_dump($result);
输出:
array(5) {
[0]=>
array(2) {
["product"]=>
string(5) "30143"
["qty"]=>
string(1) "1"
}
[1]=>
array(2) {
["product"]=>
string(5) "30144"
["qty"]=>
string(1) "2"
}
[2]=>
array(2) {
["product"]=>
string(5) "30145"
["qty"]=>
string(1) "3"
}
[3]=>
array(2) {
["product"]=>
string(5) "30146"
["qty"]=>
string(1) "5"
}
[4]=>
array(2) {
["product"]=>
string(5) "30147"
["qty"]=>
string(1) "5"
}
}

Hooray for regex solutions ...
$str = '30143*1,30144*2,30145*3,30146*5,30147*5';
if (preg_match_all('/(?<product>[^*]+)\*(?<qty>[^,]+),?/', $str, $matches, PREG_SET_ORDER)) {
$result = array_map(
function ($match) { return array_intersect_key($match, array_flip(['product', 'qty'])); },
$matches
);
print_r($result);
}
preg_match_all
来电已mostly does what you want,$matches
已经是预期结果的一部分了,它只是有一些array_intersect_key
摆脱的其他内容。

@deceze variant:
preg_match_all('~(?<product>\d+)\*(?<qty>\d+)~', $str, $result, PREG_SET_ORDER);
foreach($result as &$m) { unset($m[0], $m[1], $m[2]); }
print_r($result);
