在php中读取操作csv文件的方法有很多,最简单的可以直接使用fopen像打开txt文件打开,然后利用explode按, 分开就成了,生成也一样直接使用a,b,c,e保存成csv格式就KO,但php还提供了fputcsv函数对csv文件操作,下面我来介绍介绍。

1.生成CVS,fputcsv()将行格式化为 CSV 并写入文件指针

 代码如下 复制代码

$list = array (
    'aaa,bbb,ccc,dddd',
    '11,22,33',
    '"php","java"'
);
$fp = fopen('file.csv', 'w');
foreach ($list as $line) {
    fputcsv($fp, explode(',', $line));
}
fclose($fp);
?>


小提示,如果你csv中有中文我们需要注意一下中文问题,否则中文乱码就会和你在一起玩哦,下面给了一个实例解决中文乱码。

 代码如下 复制代码

/** by www.bKjia.c0m */
$row = 1;
$handle = fopen("file.csv","r");
//fgetcsv() 解析读入的行并找出 CSV格式的字段然后返回一个包含这些字段的数组。
while ($data = fgetcsv($handle, 1000, ",")) {
    $num = count($data);
    echo "

$num fields in line $row:
n";
    $row++;
    for ($c=0; $c   //注意中文乱码问题
  $data[$c]=iconv("gbk", "utf-8//IGNORE",$data[$c]); 
        echo $data[$c] . "
n";
    }
}
fclose($handle);
?>

读取csv文件的某一行数据

 代码如下 复制代码

 

function get_file_line( $file_name, $line ){
$n = 0;
$handle = fopen($file_name,'r');
if ($handle) {
while (!feof($handle)) {
++$n;
$out = fgets($handle, 4096);
if($line==$n) break;
}
fclose($handle);
}
if( $line==$n) return $out;
return false;
}
echo get_file_line("windows_2011_s.csv", 10);
?>


读取csv文件制定行数(行区间)

 

 代码如下 复制代码
function get_file_line( $file_name, $line_star, $line_end){
$n = 0;
$handle = fopen($file_name,"r");
if ($handle) {
while (!feof($handle)) {
++$n;
$out = fgets($handle, 4096);
if($line_star $ling[] = $out;
}
if ($line_end == $n) break;
}
fclose($handle);
}
if( $line_end==$n) return $ling;
return false;
}
$aa = get_file_line("windows_2011_s.csv", 11, 20); //从第11行到第20行
foreach ($aa as $bb){
echo $bb."
";
}
?>

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
