我正在为此使用以下函数;这是根据fputscsv评论中的一个man条目改编的。你可能想把这个阵列展平;不知道如果你进入多维空间会发生什么
<?
$data = array(
array( 'row_1_col_1', 'row_1_col_2', 'row_1_col_3' ),
array( 'row_2_col_1', 'row_2_col_2', 'row_2_col_3' ),
array( 'row_3_col_1', 'row_3_col_2', 'row_3_col_3' ),
);
?>
我的解决方案要求阵列的格式与问题中提供的不同:
<?
function outputCSV($data) {
$outputBuffer = fopen("php://output", 'w');
foreach($data as $val) {
fputcsv($outputBuffer, $val);
}
fclose($outputBuffer);
}
?>
我们定义了我们的功能:
<?
$filename = "example";
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename={$filename}.csv");
header("Pragma: no-cache");
header("Expires: 0");
outputCSV($data);
?>
然后,我们将数据输出为CSV:
// Create Some data
<?php
$data = array(
array( 'row_1_col_1', 'row_1_col_2', 'row_1_col_3' ),
array( 'row_2_col_1', 'row_2_col_2', 'row_2_col_3' ),
array( 'row_3_col_1', 'row_3_col_2', 'row_3_col_3' ),
);
// Create a stream opening it with read / write mode
$stream = fopen('data://text/plain,' . "", 'w+');
// Iterate over the data, writting each line to the text stream
foreach ($data as $val) {
fputcsv($stream, $val);
}
// Rewind the stream
rewind($stream);
// You can now echo it's content
echo stream_get_contents($stream);
// Close the stream
fclose($stream);
我已经在几个项目中使用了它,并且效果很好。我应该注意到,
outputcv
代码比我更聪明,所以我肯定我不是原始作者。不幸的是,我不知道我从哪里得到了它,所以我不能把它归功于谁。对kingjeffrey上面的解决方案进行了一点修改,用于在模板中创建和回显CSV(即-大多数框架将启用输出缓冲,并且需要在控制器中设置标题等)
//创建一些数据
也许四年后有点晚了哈哈。。。但我一直在寻找解决方案做对象到CSV,然而大多数解决方案实际上是数组到CSV
经过一些修改后,这里是我将对象转换为CSV的解决方案,我认为这非常好。希望这能帮助其他人
blah,blah,blah
blah,blah,blah
请注意,要使$key=>$value
工作,您的对象的属性必须是公共的,私有的属性将不会被获取
最终的结果是你会得到这样的结果:
Array
(
[0] => Array
(
[a] => "a"
[b] => "b"
)
[1] => Array
(
[a] => "a2"
[b] => "b2"
)
[2] => Array
(
[a] => "a3"
[b] => "b3"
)
[3] => Array
(
[a] => "a4"
[b] => "b4"
)
[4] => Array
(
[a] => "a5"
[b] => "b5"
)
)
保罗的回答很好。我对此做了一个小小的扩展,如果您有这样一个多维数组(这很常见),这非常有用:
所以我从上面取了Paul的函数:
function a2c($array, $glue = "\n")
{
$ret = [];
foreach ($array as $item) {
$ret[] = arrayToCsv($item);
}
return implode($glue, $ret);
}
并补充说:
$csv = a2c($array);
所以你可以打电话:
如果你想要一个特殊的行尾,你可以使用可选的参数“glue”来完成这个任务。根据接受的答案添加一些改进

即使$encloseAll为TRUE,也不要使用空字符串

$delimiter_esc=preg_quote($delimiter,'/');
$enclosure_esc=preg_quote($enclosure,“/”);
$output=[];
foreach($fields作为$field){
如果($field==null&&$nullToMysqlNull){
$output[]='NULL';
继续;
}
//将包含$delimiter、$enclosure或空格、换行符的字段括起来
$field=strval($field);
if(strlen($field)&($encloseAll | | | | preg| match(/(?:${delimiter|esc}}|${enclosure| esc}| \s | \r | \n | \t)/“,$field)){
$output[]=$enclosure.str_replace($enclosure,$enclosure.$enclosure,$field)。$enclosure;
}否则{
$output[]=$field;
}
}
返回内爆($delimiter,$output);
}
你可能想用你的代码所用的任何语言来标记这个问题。这将帮助你在你的问题上获得更多的眼球。:)我不认为有一种方法可以在CSV中呈现多维性,是吗?另请参见将fputcsv()
与ob_start();$df=fopen(“php://output“,‘w’);fclose($df);返回ob_get_clean()
。你好,Paulrajj,非常感谢。你真的帮了我的忙。你的帅哥!:DHi Paul,谢谢,这真的帮了我很多。你最好的!:DHi,这对我很有用。但是我有一个问题,我怎么才能在一行之后创建新行?我在for循环中添加了一个计数器,如果它是第一个索引的结尾,我会像这样附加一行新行$output[$i]。=“\r\n"; 它创建了一个新行,但也在下一行中添加了一个新单元格。存在一种边缘情况,即如果$fields
数组中的最后一个值是空字符串,则会将其丢弃。因此,如果数组长度为3个元素,且最后一个元素为空字符串,则将在空字符串之前获取值,该值由2个分隔符分隔,而不是指示最后一个值为空所需的3个分隔符。如果不允许文件创建权限,则此解决方案非常有用
