php读取csv数据保存到数组的方法_php技巧
本文实例讲述了php读取csv数据保存到数组的方法。分享给大家供大家参考。具体分析如下:
csv是常用的excel格式的替代品,很多时候我们导出数据是都会导成csv格式的,这样和excel没什么区别,下面的程序是要读取csv数据保存到数组我们要对数据进行操作,所以保存到数据,代码如下:
//echo '
'; <br> //print_r($info); <br> //echo '
foreach ($info as $c)
{
echo '学号:'.$c[0];
echo '姓名:'.$c[1];
echo '年龄:'.$c[2];
echo '身高:'.$c[3].'
';
}
final class csvtoarray{
/**
* 把csv文件解析为一个数组返回
*
* @param string $file 要解析的csv文件路径
* @param char $delimiter csv文件里的内容分隔符 默认为;
* @return array
*/
public static function open($file, $delimiter = ';'){
return self::ordenamultiarray(self::csvarray($file, $delimiter), 1);
}
private function csvarray($file, $delimiter)
{
$result = array();
$size = filesize($file) + 1;
$file = fopen($file, 'r');
$keys = fgetcsv($file, $size, $delimiter);
fseek($file,0);//这里原来的没有..自己加上..这样能读取到第一行的内容
while ($row = fgetcsv($file, $size, $delimiter))
{
for($i = 0; $i {
if(array_key_exists($i, $keys))
{
$row[$keys[$i]] = $row[$i];
}
}
print_r($row);
$result[] = $row;
}
fclose($file);
return $result;
}
private function ordenamultiarray($multiarray, $secondindex)
{
while (list($firstindex, ) = each($multiarray))
$indexmap[$firstindex] = $multiarray[$firstindex][$secondindex];
asort($indexmap);
while (list($firstindex, ) = each($indexmap))
if (is_numeric($firstindex))
$sortedarray[] = $multiarray[$firstindex];
else $sortedarray[$firstindex] = $multiarray[$firstindex];
return $sortedarray;
}
}
希望本文所述对大家的php程序设计有所帮助。
