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();
