我试图在PHP中创建一个多维数组，其中内部数组与以下示例相关联：CSV字符串$ csv：
# Results from 2015-06-16 to 2015-06-16.
date,time,label,artist,composer,album,title,duration
2015-06-16,12:00 AM,Island,U2,"Clayton- Adam,The Edge,Bono,Mullen- Larry- Jr",Songs Of Innocence,SONG FOR SOMEONE,03:46
2015-06-16,12:04 AM,Lowden Proud,"Fearing & White, Andy White, Stephen Fearing","White- Andy,Fearing- Stephen",Tea And Confidences,SECRET OF A LONG LASTING LOVE,03:10
2015-06-16,12:07 AM,Columbia,The Wallflowers,"Dylan- Jakob,Irons- Jack,Mathis- Stuart,Richling- Greg,Jaffee- Rami",Glad All Over,REBOOT THE MISSION,03:31
2015-06-16,12:10 AM,Distort Light,Bend Sinister,Moxon- Daniel,"Stories Of Brothers, Tales Of Lovers",JIMMY BROWN,03:48
第3 +行格式之后的实际数据行数是可变的。到目前为止我所做的是一个简单的多维数组：
$resultArray = str_getcsv($csv, PHP_EOL);//parse the rows
array_shift($resultArray);//shift out results first row: date info
array_shift($resultArray);//shift out results new first row: field labels
foreach($resultArray as &$row) {//parse the items in rows
$row = str_getcsv($row, ",", '"');//removes the '"' field enclosure?
}//foreach
这是一个功能多维数组，但我无法弄清楚如何使内部数组关联，所以我可以使用我预期使用的数组中的文本友好键来访问它们：
$rowFieldKeysArray = array('date', 'time', 'label', 'artist', 'composer', 'album', 'title', 'duration');
我确定使用密钥名称数组作为关联数组的键是一种简单的PHP方法，但我不知道该怎么做。我宁愿怀疑我需要做的事情：
foreach($resultArray as $rowKey => &$row) {
$row[$rowFieldKeysArray[$rowKey]] = str_getcsv($row, ",", '"');
}//foreach
但是这会产生＆＃34;警告：非法字符串偏移＆＃39;日期＆＃39; [...]＆＃34;。
我该怎么做？
编辑：根据安德鲁评论中链接提供的综合信息以及我接受的答案，我能够使用以下有效代码解决此问题：
$resultArray = str_getcsv($csv, PHP_EOL);//parse the rows
array_shift($resultArray);//shift out results first row: date info
$rowFieldKeysArray = str_getcsv( array_shift($resultArray), "," );//shift out results new first row: field labels into field key name array
//array('date', 'time', 'label', 'artist', 'composer', 'album', 'title', 'duration');//array of Key field names for associative array
// [0] [1] [2] [3] [4] [5] [6] [7] //key index
foreach($resultArray as &$row) {//parse the items in rows
$row = array_combine($rowFieldKeysArray, str_getcsv($row, ",", '"'));//array_combine replaces numeric indexes with key field labels
}//foreach
谢谢！

脚本 - 对于csv来自文件的数组
[akshay@localhost tmp]$ cat test.php
<?php
function csv_to_array($filename='', $delimiter=',')
{
if(!file_exists($filename) || !is_readable($filename))
return FALSE;
$header = NULL;
$data = array();
if (($handle = fopen($filename, 'r')) !== FALSE)
{
while (($row = fgetcsv($handle, 0, $delimiter)) !== FALSE)
{
if(!$header)
{
$header = $row;
}
else
{
if(count($header)!=count($row)){ continue; }
$data[] = array_combine($header, $row);
}
}
fclose($handle);
}
return $data;
}
print_r(csv_to_array("/tmp/test.csv"));
?>
