我在数组中有以下参考书目数据（请注意，字段按随机顺序排列 - 还有其他字段）：
Array
(
[0] => Array
(
['Pub_Name'] => Nature
['Volume'] => 6
['Pages'] => 215-217
)
[1] => Array
(
['Volume'] => 15
['Pages'] => 358-360
['Pub_Name'] => Science
)
[2] => Array
(
['Pub_Name'] => PNAS
['Pages'] => 17-19
['Volume'] => 22
)
)
例如，我想将这三个字段“合并”为一个字段['Pub_Name']=Nature, 6: 215-217。我尝试了以下 whitout 成功（我猜$Record['Pub_Name']是不正确的 sintax）：
foreach ($MyArray as $Record) {
foreach ($Record as $key => $values) {
if ($key=="Volume") {$Volumen=", ".$values;} else {$Volumen="";}
if ($key=="Pages") {$Paginas=": ".$values;} else {$Paginas="";}
}
//This is the line for which I want to know the sintax!!
$Record['Pub_Name'].=$Volumen.$Paginas;
}
不需要两个循环：
foreach ($MyArray as $Record) {
$result[]['Pub_Name'] = "{$Record['Pub_Name']}, {$Record['Pages']}: {$Record['Volume']}";
}
然后您Pub_Name在$result.
如果要修改原件，请参考& $Record：
foreach ($MyArray as &$Record) {
$Record['Pub_Name'] = "{$Record['Pub_Name']}, {$Record['Pages']}: {$Record['Volume']}";
}
或者使用key修改原数组：
foreach ($MyArray as $key => $Record) {
$MyArray[$key]['Pub_Name'] = "{$Record['Pub_Name']}, {$Record['Pages']}: {$Record['Volume']}";
}
