php使用fputcsv()函数csv文件读写数据的方法
本文实例讲述了php使用fputcsv()函数csv文件读写数据的方法。分享给大家供大家参考。具体分析如下：
fputcsv()函数用于将数据格式为csv格式,以便写入文件或者数据库.
1.将字符串写入csv文件中,代码如下:
$test_array=array(
array("111","sdfsd","sdds","43344","rrrr"),
array("sssssssss","gdfgfd","232323","wwewe","dsfds"),
array("fgfg","e4343","dsfds","w2332","xcvxc"),
array("11212","2323","344343","344343","rerreer"),
array("fds","43344444","33333333","ttttttt","gggggggggggg"),
array("kdfs","dsfdsfds","wewewe","sdsdddddddd","wwwwwwwwwww")
);
$file=fopen("test.csv","w")ordie("Can'tOpentest.csv");
foreach($test_arrayas$line_array)
{
$isSuccess=fputcsv($file,$line_array);
print$isSuccess."<br>";
if($isSuccess===false)
{
die("Can'twritecsvline".$line_array);
}
}
fclose($file)ordie("Can'tclosefiletest.csv.");fputcsv()函数返回所写入行的字符的个数或者false,当写入失败时返回false.
2.将格式化的csv字符串保存到字符串中,代码如下:
$test_array=array(
array("111","sdfsd","sdds","43344","rrrr"),
array("sssssssss","gdfgfd","232323","wwewe","dsfds"),
array("fgfg","e4343","dsfds","w2332","xcvxc"),
array("11212","2323","344343","344343","rerreer"),
array("fds","43344444","33333333","ttttttt","gggggggggggg"),
array("kdfs","dsfdsfds","wewewe","sdsdddddddd","wwwwwwwwwww")
);
ob_start();
$file=fopen("php://output","w")ordie("Can'tOpenphp://output");
foreach($test_arrayas$line_array)
{
$isSuccess=fputcsv($file,$line_array);
if($isSuccess===false)
{
die("Can'twritecsvline".$line_array);
}
}
fclose($file)ordie("Can'tclosefiletest.csv."); $result=ob_get_contents(); ob_end_clean();
