如何在php中访问数组的单值数组

我想为下面的代码访问数组中数组的单个值

现在结果：

{"result":[{"msgno":" 1","from":[{"personal":"Blind Mailer","mailbox":"mailerblind","host":"gmail.com"}],"subject":"Testing","date":"Mon, 2 Jan 2017 13:16:21 +0530"}]}

{"result":[{"msgno":" 1","from":"Blind Mailer","subject":"Testing","date":"Mon, 2 Jan 2017 13:16:21 +0530"}]}

$emails = imap_search($inbox,'SEEN'); 
$output = '';
$result=array(); 
foreach($emails as $ove) {

$headerInfo = imap_headerinfo($inbox,$ove);

$emailStructure = imap_fetchstructure($inbox,$ove);

if(!isset($emailStructure->multipart)) {
    array_push($result,array("msgno"=>$headerInfo->Msgno ,"from"=>$headerInfo->from,"subject"=>$headerInfo->subject,"date"=>$headerInfo->date));
} else {   
     array_push($result,array("msgno"=>$ove->msgno,"from"=>$ove->from,"subject"=>$ove->subject,"date"=>$ove->date));
}   
}
 echo json_encode(array('result'=>$result));

所需结果：

{"result":[{"msgno":" 1","from":[{"personal":"Blind Mailer","mailbox":"mailerblind","host":"gmail.com"}],"subject":"Testing","date":"Mon, 2 Jan 2017 13:16:21 +0530"}]}

{"result":[{"msgno":" 1","from":"Blind Mailer","subject":"Testing","date":"Mon, 2 Jan 2017 13:16:21 +0530"}]}

$emails = imap_search($inbox,'SEEN'); 
$output = '';
$result=array(); 
foreach($emails as $ove) {

$headerInfo = imap_headerinfo($inbox,$ove);

$emailStructure = imap_fetchstructure($inbox,$ove);

if(!isset($emailStructure->multipart)) {
    array_push($result,array("msgno"=>$headerInfo->Msgno ,"from"=>$headerInfo->from,"subject"=>$headerInfo->subject,"date"=>$headerInfo->date));
} else {   
     array_push($result,array("msgno"=>$ove->msgno,"from"=>$ove->from,"subject"=>$ove->subject,"date"=>$ove->date));
}   
}
 echo json_encode(array('result'=>$result));

php代码：

{"result":[{"msgno":" 1","from":[{"personal":"Blind Mailer","mailbox":"mailerblind","host":"gmail.com"}],"subject":"Testing","date":"Mon, 2 Jan 2017 13:16:21 +0530"}]}

{"result":[{"msgno":" 1","from":"Blind Mailer","subject":"Testing","date":"Mon, 2 Jan 2017 13:16:21 +0530"}]}

$emails = imap_search($inbox,'SEEN'); 
$output = '';
$result=array(); 
foreach($emails as $ove) {

$headerInfo = imap_headerinfo($inbox,$ove);

$emailStructure = imap_fetchstructure($inbox,$ove);

if(!isset($emailStructure->multipart)) {
    array_push($result,array("msgno"=>$headerInfo->Msgno ,"from"=>$headerInfo->from,"subject"=>$headerInfo->subject,"date"=>$headerInfo->date));
} else {   
     array_push($result,array("msgno"=>$ove->msgno,"from"=>$ove->from,"subject"=>$ove->subject,"date"=>$ove->date));
}   
}
 echo json_encode(array('result'=>$result));

array\u push

会将项目附加到数组中。由于追加的本身是一个数组，因此在数组中有一个数组，而不是在单个数组中有所有值

相反，您希望使用

array\u merge

，它将获取两个数组并将它们连接在一起，以创建单个一维数组。请参见此处的PHP手册：
