php - PHP：CSV到数组将值存储到数组中，显示在print_r中，访问时为空
问题描述
我的任务是使用旧站点数据更新新站点。因此将 csv 导入自定义帖子类型。
我有导入工作，但不幸的是，javascript 端不能很好地处理包含 html 的 csv 列。
为了解决这个问题，我发现我的解析函数对 html 列没有任何问题。现在错误恰好是，我的数组的第一个键没有保留它的数据。以前没见过这个，有点脑洞。让我知道您是否以前见过这个以及如何解决它。它也发生在每一行，不返回一个艺术键。
首先我的用于解析 csv 的 wordpress/php 代码
function waw_article_csv_to_array($filename='', $delimiter=',')
{
// this is an important setting!
ini_set('auto_detect_line_endings', true);
// IF the file doesn't exist or the file is not readable return false
if(!file_exists($filename) || !is_readable($filename))
return FALSE;
// setup our return data
$return_data = array();
// IF we can open and read the file
if (($handle = fopen($filename, "r")) !== FALSE) {
$row = 0;
// while data exists loop over data
while (($data = fgetcsv($handle, 0, ",")) !== FALSE) {
// count the number of items in this data
$num = count($data);
// loop over all items and append them to our row data
for ($c=0; $c < $num; $c++) {
// if this is the first row set it up as our header
if( $row == 0):
$header[] = $data[$c];
else:
// all rows greater than 1
//add to $return_data
$return_data[$row-1][$header[$c]] = $data[$c];
endif;
}
$row++;
}
// close our file
fclose($handle);
}
// Log Testing
error_log('Array of Keys'. print_r( array_keys($return_data[30]),true));
error_log('Return Data Array: '. print_r($return_data[30],true));
error_log('artkey:'. $return_data[30]['artkey']);
error_log('Arttitle:'.$return_data[30]['arttitle']);
error_log('issue:'.$return_data[30]['issue']);
error_log('year:'.$return_data[30]['year']);
error_log('teaser:'.$return_data[30]['teaser']);
error_log('story:'.$return_data[30]['story']);
error_log('images:'.$return_data[30]['images']);
error_log('author:'.$return_data[30]['author']);
error_log('publish:'.$return_data[30]['publish']);
error_log('sidebardisplay:'.$return_data[30]['sidebardisplay']);
error_log('notes:'.$return_data[30]['notes']);
error_log('region:'.$return_data[30]['region']);
error_log('cats:'.$return_data[30]['cats']);
error_log('Return Data Array[28]: '. print_r($return_data[28],true));
error_log('artkey[28]:'. $return_data[28]['artkey']);
error_log('Return Data Array[29]: '. print_r($return_data[29],true));
error_log('artkey[29]:'. $return_data[29]['artkey']);
error_log('Return Data Array[30]: '. print_r($return_data[30],true));
error_log('artkey[30]:'. $return_data[30]['artkey']);
error_log('Var Dump 30:'.var_dump($return_data[30]));
return $return_data;
}
在我的日志测试期间发现了这个问题，我只检查了我选择的任何行，在这个例子中的第 30 行。当我访问“artkey”时，它返回空或空白。
下面是数组键，以及数组的 print_r，以及返回的日志值。
