如果我尝试导入csv文件,则还会导入所有空行。
我有一个带有csv文件的表单
以下是表单操作代码
$file = $_FILES['file']['tmp_name'];
$allowedExts = array("csv");
$temp = explode(".", $_FILES["file"]["name"]);
$extension = end($temp);
if (!in_array($extension, $allowedExts)) {
$this->session->set_flashdata('msg', 'Please upload a csv file format.');
}
else {
$handle = fopen($file, "r");
$c = 0;
$flag = true;
while(($filesop = fgetcsv($handle, 0, ",")) !== false)
{
if($flag) { $flag = false; continue; } //to skip the title row
if($filesop != NULL ) { //CONDITION TO CHECK EMPTY ROWS (DOES not work..)
$data[] = array(
'id'=>0, //uploader user id
'field1' => (isset($filesop[14]) ? $filesop[14] : "" ),
'field2' => (isset($filesop[15]) ? $filesop[15] : "" ),
'field3' => (isset($filesop[1]) ? $filesop[1] : "" ),
'field4' => (isset($filesop[13]) ? $filesop[13] : "" ),
'field5' => (isset($filesop[6]) ? $filesop[6] : "" ),
'field6' => (isset($filesop[2]) ? $filesop[2] : "" ),
'field7' => (isset($filesop[5]) ? $filesop[5] : "" ),
'field8' => (isset($filesop[3]) ? $filesop[3] : "" ),
'field9' => (isset($filesop[4]) ? $filesop[4] : "" ),
);
}
}
echo "<pre>";
print_r($data);
exit;
请帮我修复,我该怎么办才能将空行导入
答案 0 :(得分:1)
我会使用array_filter从数组中删除空元素,然后检查是否有任何内容。
while(($filesop = fgetcsv($handle, 0, ",")) !== false){
$empty_filesop = array_filter( array_map('trim', $filesop));
if( !empty( $empty_filesop ) ){
.....
}
}
带有trim的数组映射,将修剪数据以删除具有空格的行,例如,{space},
将其视为:
foreach( $empty_filesop as &$item )
$item = trim( $item );
另外,请注意PHP会将一些内容视为空,您可能不会将其视为空,并将使用标准array_filter删除它们,例如0
中的,0,
或array( 0, 'blah' )
元素0
将被删除。如果您需要更高的准确度,可以执行以下操作:
$empty_filesop = array_filter(
array_map('trim', $filesop),
function( $item ){
return strlen( $item ); //return the string length of $item ( 0 is false > 0 is true )
}
);
如果您依赖于元素位置,如果有空行则会更改,因此请复制它以进行检查。例如,使用$empty_filesop
,这样就不会使用过滤器改变实际行...

对于标题,请执行此操作(我不知道orignal键):
$headers = false;
$order = ['id'=>0, 'org3'=>'', 'org2'=>'', 'org1'=>''];
while(($filesop = fgetcsv($handle, 0, ",")) !== false)
{
if(!$headers) { $headers = $filesop; continue; }
$empty_filesop = array_filter( array_map('trim', $filesop));
if( !empty($empty_filesop)){
//check for empty rows
if( count( $headers ) == count($filesop) ) {
//check for rows with extra or missing delimiters.
$data[] = array_replace( $order, array_combine( $headers, $filesop)); //combine with original headers, and replace the data in the 'order row' to re-order.
}else{
//row is missing or has extra delimiters.
}
}
}

更改
host :'127.4.188.2',
port :'3306', // if this doesn't work try removing port once
user:'adminfxxxxx',
password:'xxxxxxxxx',
database:'xxxxxxxxx', //specify database Name
要
if ($filesop != null)
