我正在尝试使用PHP电子表格库读取CSV文件。
我成功获取了数据但是将逗号分隔到数组中是错误的。
Array
(
[0] => Array
(
[0] => Id,Record,Book,Description,Date,Action
[1] =>
[2] =>
)
[1] => Array
(
[0] => 1306,5466,84,Item,04-05-2018 06
[1] => 26
[2] => 28,Auto Show
)
)
当我看到输出时，它看起来像这样：
Array
(
[0] => Array
(
[0] => Id
[1] => Record
[2] => Book
[3] => Description
[4] => Date
[5] => Action
)
[1] => Array
(
[0] => 1306
[1] => 5466
[2] => 84
[3] => Item
[4] => 04-05-2018 06:26:28
[5] => Auto Show
)
)
代替：
$(document).ready(function() {
var state = {
status: "inProgress",
turn: "human", //can be human or AI
game: 1,
turnSwitch: function() {
if (this.turn == "human") {

您是否尝试过强制行结尾一致？我之前遇到过这种情况，在解析CSV之前必须添加PHP ini设置：
ini_set('auto_detect_line_endings',TRUE)
把它放在$ reader之前

这是我用于CSV的类，假设你至少有PHP 5.5：
<?php
use Exception;
use InvalidArgumentException;
use SplFileObject;
use NoRewindIterator;
class LargeFile {
const ERROR_UNABLE = 'ERROR: Unable to open file';
const ERROR_TYPE = 'ERROR: Type must be "ByLength", "ByLine", or "Csv"';
protected $file;
protected $allowed_types = [ 'ByLine', 'ByLength', 'Csv' ];
/**
* LargeFile constructor.
*
* @param $filename
* @param string $mode
*
* @throws Exception
*
* Populates $file with new SPL File object instance.
*/
public function __construct($filename, $mode = 'r') {
if (!file_exists($filename)) {
$message = __METHOD__ . ' : ' . self::ERROR_UNABLE . PHP_EOL;
$message .= strip_tags($filename) . PHP_EOL;
throw new Exception($message);
}
$this->file = new SplFileObject($filename, $mode);
}
/**
* @return \Generator|int
*
* References SplFileObject method to read the file one line
* at a time with fgets.
*
* Suitable for smaller text files like Csvs and / or
* include line feeds.
*/
protected function fileIteratorByLine() {
$count = 0;
while (!$this->file->eof()) {
yield $this->file->fgets();
$count++;
}
return $count;
}
/**
* @param $numBytes
*
* @return \Generator|int
*
* References SplFileObject method to read the file one line
* at a time with freads.
*
* Suitable for larger binary files.
*/
protected function fileIteratorByLength($numBytes) {
$count = 0;
while (!$this->file->eof()) {
yield $this->file->fread($numBytes);
$count++;
}
return $count;
}
protected function fileIteratorCsv() {
$count = 0;
while (!$this->file->eof()) {
yield $this->file->fgetcsv();
$count++;
}
return $count;
}
/**
* @param string $type
* @param null $numBytes
*
* @return NoRewindIterator
*/
public function getIterator($type = 'ByLine', $numBytes = null) {
if (!in_array($type, $this->allowed_types)) {
$message = __METHOD__ . ' : ' . self::ERROR_TYPE . PHP_EOL;
throw new InvalidArgumentException($message);
}
$iterator = 'fileIterator' . $type;
return new NoRewindIterator($this->$iterator($numBytes));
}
}
你可以像这样使用它：
$largeFile = new LargeFile($file);
// tell it use the CSV iterator
$iterator = $largeFile->getIterator('Csv');
// start iterator and pull out header row as $rawHeaders
$rawHeaders = $iterator->current();
$headerIterator = new \ArrayIterator;
foreach ($rawHeaders as $header) {
$headerIterator->append(strtolower("`$header`"));
}
$headers = $headerIterator->getArrayCopy();
// move pointer to the data rows
$iterator->next();
// loop through each row
foreach( $iterator as $row ) {
// do stuff with each row
print_r($row);
}
