我需要通过匹配索引值从序列化数组中获取值。我的未序列化数组值类似于
Array ( [info1] => test service [price_total1] => 10
[info2] => test servicing [price_total2] => 5 )
我需要显示这样的数组
Array ( [service_1] => Array ([info]=>test service [price_total] => 10 )
[service_2] => Array ([info]=>test servicing [price_total] => 5 ))
买我得到的结果如下
Array ( [service_1] => Array ( [price_total] => 10 )
[service_2] => Array ( [price_total] => 5 ) )
我的编码是
public function getServices($serviceinfo) {
$n = 1;
$m = 1;
$matches = array();
$services = array();
print_r($serviceinfo);
if ($serviceinfo) {
foreach ($serviceinfo as $key => $value) {
if (preg_match('/info('d+)$/', $key, $matches)) {
print_r($match);
$artkey = 'service_' . $n;
$services[$artkey] = array();
$services[$artkey]['info'] = $serviceinfo['info' . $matches[1]];
$n++;
}
if ($value > 0 && preg_match('/price_total('d+)$/', $key, $matches)) {
print_r($matches);
$artkey = 'service_' . $m;
$services[$artkey] = array();
$services[$artkey]['price_total'] = $serviceinfo['price_total' . $matches[1]];
$m++;
}
}
}
if (empty($services)) {
$services['service_1'] = array();
$services['service_1']['info'] = '';
$services['service_1']['price_total'] = '';
return $services;
}
return $services;
}
我尝试打印匹配项,它将给出结果
Array ( [0] => info1 [1] => 1 ) Array ( [0] => price_total1 [1] => 1 )
Array ( [0] => info2 [1] => 2 ) Array ( [0] => price_total2 [1] => 2 )
提前谢谢。
试试这个。 缩短版本,不要使用preg_match
function getServices($serviceinfo) {
$services = array();
if (is_array($serviceinfo) && !empty($serviceinfo)) {
foreach ($serviceinfo as $key => $value) {
if(strpos($key, 'info') === 0){
$services['service_'.substr($key, 4)]['info']=$value;
}elseif (strpos($key, 'price_total') === 0){
$services['service_'.substr($key, 11)]['price_total']=$value;
}
}
}
return $services;
}
$data = array('info1'=>'test service','price_total1'=>10,'info2'=>'test servicing','price_total2'=>5);
$service = getServices($data);
print_r($service);
