Detailed explanation of reading csv file content based on PHP

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);
?>

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);
?>

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.

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);
}
}
?>

<?
$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++;
}
?>
