这个有点长,所以我提前道歉。
我试图用c解析csv文件;分隔符,由于某种原因,它只解析第一个字符串,然后继续前进到文件中的下一行。我在最后的Csvimport类中做了print_r($content); break;
来测试数据导入,这就是它给我的:
Array ( [1] => Array ( [Key1] => Key1 ) [2] => Array ( [Key2] => Key2 ) ) 1
这是一个问题。第二个是,当我让它进入视图时,它会为$field['key']
,$field['address']
,$field['lotno']
等所在的每一行引发错误,表示密钥,地址,lotno未定义。
这是我的csv文件:
Key1;Address1;LotNo1;Acres1;YrBuilt1;
Key2;Address2;LotNo2;Acres2;YrBuilt2;
这是我的csv导入库文件:
class Csvimport {
var $fields;/** columns names retrieved after parsing */
var $separator = ';';/** separator used to explode each line */
var $enclosure = '"';/** enclosure used to decorate each field */
var $max_row_size = 4096;/** maximum row size to be used for decoding */
function parse_file($p_Filepath) {
$file = fopen($p_Filepath, 'r');
$this->fields = fgetcsv($file, $this->max_row_size, $this->separator, $this->enclosure);
$keys = str_getcsv($this->fields[0]);
$i = 1;
while (($row = fgetcsv($file, $this->max_row_size, $this->separator, $this->enclosure)) != false) {
if ($row != null) { // skip empty lines
$values = str_getcsv($row[0]);
if (count($keys) == count($values)) {
$arr = array();
for ($j = 0; $j < count($keys); $j++) {
if ($keys[$j] != "") {
$arr[$keys[$j]] = $values[$j];
}
}
$content[$i] = $arr;
$i++;
}
}
}
fclose($file);
// echo print_r($content); break;
return $content;
}
}
这是我的控制者:
$import = './application/imports/unitimport.csv';
$this->load->library('csvimport');
$data['importdata'] = $this->csvimport->parse_file($import);
这是我的观点:
<?php foreach($importdata as $field): ?>
<tr>
<td><p><?php echo $field['key'] ?><p></td>
<td><p><?php echo $field['address'] ?><p></td>
<td><p><?php echo $field['lotno'] ?><p></td>
<td><p><?php echo $field['acres'] ?><p></td>
<td><p><?php echo $field['yrbuilt'] ?><p></td>
</tr>
<?php endforeach ?>
我错过了什么?
答案 0 :(得分:1)
这是一个老问题......但是你走了:
这一行:
$this->fields = fgetcsv($file, $this->max_row_size, $this->separator, $this->enclosure);
将文件的第一行保存到$ this-&gt;字段中的数组中。所以在这一点上:
$this->fields = array('Key1','Address1','LotNo1','Acres1','YrBuilt1');
在下一行:
$keys = str_getcsv($this->fields[0]);
str_getcsv()正在解析$this-fields
的第一个值并将其转换为数组。所以在这一点上:
$keys = array('Key1');
当您使用以下行迭代数据行时,您会重复同样的错误:
$values = str_getcsv($row[0]);
$values
仅存储第一个数据列,因为这是唯一被解析的项目。
以下代码应该有效:
class Csvimport
{
var $fields;/** columns names retrieved after parsing */
var $separator = ';';/** separator used to explode each line */
var $enclosure = '"';/** enclosure used to decorate each field */
var $max_row_size = 4096;/** maximum row size to be used for decoding */
function parse_file($p_Filepath)
{
$file = fopen($p_Filepath, 'r');
$this->fields = fgetcsv($file, $this->max_row_size, $this->separator, $this->enclosure);
$content = array();
$i = 1;
while (($row = fgetcsv($file, $this->max_row_size, $this->separator, $this->enclosure)) != false)
{
if ($row != null) // skip empty lines
{
for ($j = 0; $j < count($this->fields); $j++)
{
$content[$i][$this->fields[$j]] = $row[$j];
}
$i++;
}
}
fclose($file);
return $content;
}
}
