我有一些类似下面的字符串:
'STRIPLED 9.6W 24V 2.7K 120LED IP20 1CM',
'STRIPLED 9.6W 24V 3K 120LED IP20 1CM',
'STRIPLED H 6 W 24V 4K 140 LED IP20 1CM',
'STRIPLED HO 12.3 W 24V 3K 128 LED IP65 1CM',
'STRIPLED HO 20W 24V 2.7K 280 LED IP65 1CM',
'STRIPLED 14.4W 24V 2.7K 180 LED IP65 1 CM',
我试图找到一些字符并创建像这样的数组
预期结果:
Array
(
[0] => Array
(
[power] => 9.6W 24V
[temp] => 2.7
[degrees] => IP20
)
[1] => Array
(
[power] => 9.6W 24V
[temp] => 3
[degrees] => IP20
)
[2] => Array
(
[power] => HO 12.3 W 24V
[temp] => 3
[degrees] => IP65
)
)
但是我无法找到正确的解决方案。
说明:STRIPLED 9.6W 24V 2.7K 120LED IP20 1CM
这里,W&V表示功率,K表示温度,IP表示度数
我尝试过的代码:
<?php
$descriptions = [
'STRIPLED 9.6W 24V 2.7K 120LED IP20 1CM',
'STRIPLED 9.6W 24V 3K 120LED IP20 1CM',
'STRIPLED H 6 W 24V 4K 140 LED IP20 1CM',
'STRIPLED HO 12.3 W 24V 3K 128 LED IP65 1CM',
'STRIPLED HO 20W 24V 2.7K 280 LED IP65 1CM',
'STRIPLED 14.4W 24V 2.7K 180 LED IP65 1 CM',
];
$desc = [];
foreach($descriptions as $key=>$val){
$desc[$key]['power'] = strstr($val, 'V', true);
$desc[$key]['temp'] = strstr($val, 'K', true);
$desc[$key]['degrees'] = strstr($val, 'IP', true);
}
echo "<pre>";
print_r($desc).exit;
?>
我看到这样的输出:
Array
(
[0] => Array
(
[power] => STRIPLED 9,6W 24
[temp] => STRIPLED 9,6W 24V 2,7
[degrees] => STR
)
[1] => Array
(
[power] => STRIPLED 9,6W 24
[temp] => STRIPLED 9,6W 24V 3
[degrees] => STR
)
[2] => Array
(
[power] => STRIPLED H 6 W 24
[temp] => STRIPLED H 6 W 24V 4
[degrees] => STR
)
[3] => Array
(
[power] => STRIPLED HO 12,3 W 24
[temp] => STRIPLED HO 12,3 W 24V 3
[degrees] => STR
)
[4] => Array
(
[power] => STRIPLED HO 20W 24
[temp] => STRIPLED HO 20W 24V 2,7
[degrees] => STR
)
[5] => Array
(
[power] => STRIPLED 14,4W 24
[temp] => STRIPLED 14,4W 24V 2,7
[degrees] => STR
)
)
任何人都可以给我解决方案以创建预期的结果。
谢谢

我认为使用preg_match
可能是提取所需数据的最简单方法。根据您的样本数据,此正则表达式应该起作用:
^\w+\s+([^V]+V)\s+([\d.,]+)K.*?(IP\d+)
这会寻找一个单词,然后是一些非V
字符(“电源”部分),然后是K
(“温度”部分)之前的数字,最后是一个匹配IP
的字符串,后跟一些数字(“度”部分)。您可以使用以下代码(使用array_map
来处理数组):
$descriptions = [
'STRIPLED 9.6W 24V 2.7K 120LED IP20 1CM',
'STRIPLED 9.6W 24V 3K 120LED IP20 1CM',
'STRIPLED H 6 W 24V 4K 140 LED IP20 1CM',
'STRIPLED HO 12.3 W 24V 3K 128 LED IP65 1CM',
'STRIPLED HO 20W 24V 2.7K 280 LED IP65 1CM',
'STRIPLED 14.4W 24V 2.7K 180 LED IP65 1 CM',
];
$desc = array_map(function ($v) {
preg_match('/^\w+\s+([^V]+V)\s+([\d.,]+)K.*?(IP\d+)/', $v, $m);
array_shift($m);
return $m; }, $descriptions);
print_r($desc);
输出示例数据:
Array
(
[0] => Array
(
[0] => 9.6W 24V
[1] => 2.7
[2] => IP20
)
[1] => Array
(
[0] => 9.6W 24V
[1] => 3
[2] => IP20
)
[2] => Array
(
[0] => H 6 W 24V
[1] => 4
[2] => IP20
)
[3] => Array
(
[0] => HO 12.3 W 24V
[1] => 3
[2] => IP65
)
[4] => Array
(
[0] => HO 20W 24V
[1] => 2.7
[2] => IP65
)
[5] => Array
(
[0] => 14.4W 24V
[1] => 2.7
[2] => IP65
)
)

您也可以尝试以下方法:
<?php
$arrays = [
'STRIPLED 9.6W 24V 2.7K 120LED IP20 1CM',
'STRIPLED 9.6W 24V 3K 120LED IP20 1CM',
'STRIPLED H 6 W 24V 4K 140 LED IP20 1CM',
'STRIPLED HO 12.3 W 24V 3K 128 LED IP65 1CM',
'STRIPLED HO 20W 24V 2.7K 280 LED IP65 1CM',
'STRIPLED 14.4W 24V 2.7K 180 LED IP65 1 CM'
];
foreach ($arrays as $array){
//remove STRIPLED
$result = [];
$removedStripled = str_replace('STRIPLED ', "", $array);
$arr = strtok($removedStripled, 'V');
$result['power'] = $arr.'V';
$temp = str_replace($arr.'V', "", $removedStripled);
$arr = strtok($temp, 'K');
$result['temp'] = $arr;
preg_match("/IP.*[0-9\s]/", $removedStripled, $match);
$degrees = explode(' ', $match[0]);
$result['degress'] = $degrees[0];
echo "<pre>";
print_r($result);
echo "</pre>";
}
