這期內容當中小編將會給大家帶來有關php中的csv文件怎么利用fputcsv()函數進行讀取，文章內容豐富且以專業的角度為大家分析和敘述，閱讀完這篇文章希望大家可以有所收獲。

fputcsv() 函數用于將數據格式為csv格式,以便寫入文件或者數據庫.

1.將字符串寫入csv文件中,代碼如下:

復制代碼 代碼如下:

$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()函數返回所寫入行的字符的個數或者false,當寫入失敗時返回false.

2.將格式化的csv字符串保存到字符串中,代碼如下:

復制代碼 代碼如下:

$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);
        }
}

fclose($file) or die("Can't close file test.csv.");
$result = ob_get_contents();
ob_end_clean();
以用fgetcsv(file,length,separator,enclosure)函數讀取csv文件.

fgetcsv的參數說明如下:

file：需要讀取的csv文件，此參數是必需的。

length：表示大于csv文件中最長的行的長度的值。php5之前是必需參數。在php5中是可選參數，如果不設置此參數或者將其設為0，php將會讀取.

一整行的數據。如果行的長度超過8192個字節時，應該將length值設定一個數，而不是讓php自動去計算行的長度。

separator：指定數據的分隔符，默認是逗號，如果指定為“；”，那么fgetcsv函數將按照“；”來解析行數據。

fgetcsv的返回值:

根據file的一行數據,返回一個數組,如果讀取文件出錯,則返回false,到達文件尾部時,也返回false.

下面是一個讀取test.csv文件的例子:

復制代碼 代碼如下:

$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!");
