《PHP应用：php使用fputcsv()函数csv文件读写数据的方法》要点：
本文介绍了PHP应用：php使用fputcsv()函数csv文件读写数据的方法，希望对您有用。如果有疑问，可以联系我们。
PHP编程本文实例讲述了php使用fputcsv()函数csv文件读写数据的办法.分享给大家供大家参考.具体分析如下：
PHP编程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.
PHP编程1.将字符串写入csv文件中,代码如下:
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")
);
$file = fopen("test.csv","w") or die("Can't Open test.csv");
foreach($test_array as $line_array)
{
$isSuccess = fputcsv($file,$line_array);
print $isSuccess."<br>";
if($isSuccess===false)
{
die("Can't write csv line".$line_array);
}
}
fclose($file) or die("Can't close file test.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.
PHP编程2.将格式化的csv字符串保存到字符串中,代码如下:
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();
$file = fopen("php://output","w") or die("Can't Open php://output");
foreach($test_array as $line_array)
{
$isSuccess = fputcsv($file,$line_array);
if($isSuccess===false)
{
die("Can't write csv line".$line_array);
}
}
PHP编程fclose($file) or die("Can't close file test.csv.");
$result = ob_get_contents();
ob_end_clean();
以用fgetcsv(file,length,separator,enclosure)函数读取csv文件.
PHP编程fgetcsv的参数说明如下:
PHP编程file：需要读取的csv文件,此参数是必需的.
PHP编程length：表示大于csv文件中最长的行的长度的值.php5之前是必需参数.在php5中是可选参数,如果不设置此参数或者将其设为0,php将会读取.
PHP编程一整行的数据.如果行的长度超过8192个字节时,应该将length值设定一个数,而不是让php自动去计算行的长度.
PHP编程separator：指定数据的分隔符,默认是逗号,如果指定为“；”,那么fgetcsv函数将依照“；”来解析行数据.
PHP编程fgetcsv的返回值:
PHP编程根据file的一行数据,返回一个数组,如果读取文件出错,则返回false,到达文件尾部时,也返回false.
PHP编程下面是一个读取test.csv文件的例子:
代码如下:
$file = fopen('test.csv','r') or die("Can't open file test.csv");
$color="#ff0000";
print '<table border=0>';
while($csv_line=fgetcsv($file))
{
print "<tr>";
$len = count($csv_line);
for($i=0;$i<$len;$i++)
{
if($i%2==0)$color="#cccccc";
else $color="#999999";
print '<td bgcolor='.$color.'>'.htmlentities($csv_line[$i]).'</td>';
}
print "</tr>";
}
print '</table>';
fclose($file) or die("Can't close file test.csv!");
