我如何解析csv文件以先获取列名,然后获取与其相关的行?
这是我的CSV
column1,column2,column3,column4,column5column1_row1,column2_row1,column3_row1,column4_row1,column5_row1
column1_row2,column2_row2,column3_row2,column4_row2,column5_row2
column1_row3,column2_row3,column3_row3,column4_row3,column5_row3
column1_row4,column2_row4,column3_row4,column4_row4,column5_row4
column1_row5,column2_row5,column3_row5,column4_row5,column5_row5
column1_row6,column2_row6,column3_row6,column4_row6,column5_row6
column1_row7,column2_row7,column3_row7,column4_row7,column5_row7
column1_row8,column2_row8,column3_row8,column4_row8,column5_row8
column1_row9,column2_row9,column3_row9,column4_row9,column5_row9
第一行是列的名称。我试过fgetcsv(),但所有要做的就是显示所有行。而不是我想要的。我该怎么做?
因此,如果我将数据最后放入数组中,我将能够打印出表格格式的数据,就像excel中所示。
谢谢
这是我的样本:
$filename = "upload/sample.csv";if (($handle = fopen($filename, 'r')) !== FALSE)
{
while (($row = fgetcsv($handle, 1000, ",")) !== FALSE)
{
print_r($row);
}
}
这是我的输出:(我将$ row放到pre中,以便可以显示它)
Array(
[0] => column1
[1] => column2
[2] => column3
[3] => column4
[4] => column5
column1_row1
[5] => column2_row1
[6] => column3_row1
[7] => column4_row1
[8] => column5_row1
column1_row2
[9] => column2_row2
[10] => column3_row2
[11] => column4_row2
[12] => column5_row2
column1_row3
[13] => column2_row3
[14] => column3_row3
[15] => column4_row3
[16] => column5_row3
column1_row4
[17] => column2_row4
[18] => column3_row4
[19] => column4_row4
[20] => column5_row4
column1_row5
[21] => column2_row5
[22] => column3_row5
[23] => column4_row5
[24] => column5_row5
column1_row6
[25] => column2_row6
[26] => column3_row6
[27] => column4_row6
[28] => column5_row6
column1_row7
[29] => column2_row7
[30] => column3_row7
[31] => column4_row7
[32] => column5_row7
column1_row8
[33] => column2_row8
[34] => column3_row8
[35] => column4_row8
[36] => column5_row8
column1_row9
[37] => column2_row9
[38] => column3_row9
[39] => column4_row9
[40] => column5_row9
)
回答:
要一次阅读所有内容,可以使用:
$csv = array_map("str_getcsv", file("file1.csv",FILE_SKIP_EMPTY_LINES));$keys = array_shift($csv);
要将所有行变成一个很好的关联数组,可以应用:
foreach ($csv as $i=>$row) { $csv[$i] = array_combine($keys, $row);
}
