我想过滤csv文件并添加条件然后获得转换。
我的问题是我需要放置过滤器以转换正确的数据吗?
条件(如果第1列的值不等于选项1)
file_data.csv(标签式)文件:
Group Option Data Value
Group1 Option 1 DATA01 2
Group1 Option 1 DATA02 3
Group1 Option 1 DATA02 2
Group1 Option 1 DATA03 1
Group1 Option 1 DATA03 2
Group2 Option 2 DATA04 3
Group4 Option 4 DATA05 7
要进行转换的php文件:
$tsvFile = new SplFileObject('file_data.csv');
$tsvFile->setFlags(SplFileObject::READ_CSV);
$tsvFile->setCsvControl("\t");
$file = fopen('file.csv', 'w');
$header = array('data', 'value');
fputcsv($file, $header, ',', '"');
$newData = array();
foreach ($tsvFile as $line => $row) {
if($row[1] != 'Option 1'){ // + Here
if ($line > 0) {
//if($row[1] != 'Option 1'){ //-From here
if (isset($newData[$row[2]])) {
$newData[$row[2]]+= $row[3];
} else {
$newData[$row[2]] = $row[3];
}
}
}
}
foreach ($newData as $key => $value) {
fputcsv($file, array($key, $value), ',', '"');
}
fclose($file);
答案 0 :(得分:0)
$tsvFile = new SplFileObject('file_data.csv');
$tsvFile->setFlags(SplFileObject::READ_CSV);
$tsvFile->setCsvControl("\t");
$file = fopen('file.csv', 'w');
$header = array('data', 'value');
fputcsv($file, $header, ',', '"');
$newData = array();
foreach ($tsvFile as $line => $row) {
if($row[1] != 'Option 1'){ // + Here
if ($line > 0) {
//if($row[1] != 'Option 1'){ //-From here
if (isset($newData[$row[2]])) {
$newData[$row[2]]+= $row[3];
} else {
$newData[$row[2]] = $row[3];
}
}
}
}
foreach ($newData as $key => $value) {
fputcsv($file, array($key, $value), ',', '"');
}
fclose($file);
