Detailed explanation of reading csv file content based on PHP

Dec 26, 2016 pm 02:35 PM

Read the data of all rows in the csv file at one time

<?php 
$file = fopen(&#39;windows_2011_s.csv&#39;,&#39;r&#39;); 
while ($data = fgetcsv($file)) { //每次读取CSV里面的一行内容
//print_r($data); //此为一个数组,要获得每一个数据,访问数组下标即可
$goods_list[] = $data;
 }
//print_r($goods_list);
/* foreach ($goods_list as $arr){
    if ($arr[0]!=""){
        echo $arr[0]."<br>";
    }
} */
 echo $goods_list[2][0];
 fclose($file);
?>
Copy after login


Read the data of a certain row of the csv file

<?php
function get_file_line( $file_name, $line ){
  $n = 0;
  $handle = fopen($file_name,&#39;r&#39;);
  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);
?>
Copy after login

Read the csv file to formulate Number of lines (line interval)

<?php
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 <= $n){
                $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.
Copy after login

Two other methods found on the Internet (haven’t tested it, I don’t know if it works)

<?
$handle=fopen("1.csv","r");
while(!feof($handle)){
$buffer=fgetss($handle,2048);
$data=explode(",",$buffer);
$num=count($data);
for($i=0;$i<$num;$i++){
print_r($data);
}
}
?>
Copy after login
<?
$handle=fopen("1.csv","r");
$row=1;
while($data=fgetcsv($handle,1000,",")){
$num=count($data);
for($i=0;$i<$num;$i++){
echo $data[$i];
}
$row++;
}
?>
Copy after login

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. 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,
