Homephp教程php手册php搜索csv表格中是否存在指定数据

php搜索csv中的数据原理是打开csv文件,然后一行行搜索指定的内容是否包含在我们读取这代码中,如果是返回true,搜索csv中指定内容,代码如下:

$fh = @fopen("csv_file_name", "r");
if ($fh) {
    if (flock($fh, lock_ex)) {
        while (!feof($fh)) {
            $line = fgets($fh);
            if (strstr($line, $target_email_address) !== false) {
                $data = split(",", $line); // $data *is* an array
                
            }
        }
        flock($fh, lock_un);
    }
    fclose($fh);
}
