PHP fgetcsv 定义和用法
PHP fgetcsv() 函数从文件指针中读入一行并解析 CSV 字段。
与PHP fgets() 类似,不同的是 PHP 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。
fgetcsv() 出错时返回 FALSE,包括碰到文件结束时。
注释:从 PHP 4.3.5 起,PHP fgetcsv() 的操作是二进制安全的。
语法
fgetcsv(file,length,separator,enclosure) |
参数 | 描述 |
file | 必需。规定要检查的文件。 |
length | 可选。规定行的最大长度。必须大于 CVS 文件内最长的一行。 在 PHP 5 中该参数是可选的。在 PHP 5 之前是必需的。 如果忽略(在 PHP 5.0.4 以后的版本中设为 0)该参数的话,那么长度就没有限制,不过可能会影响执行效率。 |
separator | 可选。设置字段分界符(只允许一个字符),默认值为逗号。 |
enclosure | 可选。设置字段环绕符(只允许一个字符),默认值为双引号。 该参数是在 PHP 4.3.0 中添加的。 |
注释:CSV 文件中的空行将被返回为一个包含有单个 null 字段的数组,不会被当成错误。
注释:该函数对区域设置是敏感的。比如说 LANG 设为 en_US.UTF-8 的话,单字节编码的文件就会出现读取错误。
注释:如果碰到 PHP 在读取文件时不能识别 Macintosh 文件的行结束符,可以激活 auto_detect_line_endings 运行时配置选项。
例子 1
复制代码 代码如下:
$file = fopen("contacts.csv","r");
print_r(fgetcsv($file));
fclose($file);
?>
CSV 文件:
George, John, Thomas, USA James, Adrew, Martin, USA
输出类似:
Array ( [0] => George [1] => John [2] => Thomas [3] => USA )
例子 2
复制代码 代码如下:
$file = fopen("contacts.csv","r");
while(! feof($file)) { print_r(fgetcsv($file));
} fclose($file);
?>
CSV 文件:
George, John, Thomas, USA James, Adrew, Martin, USA
输出类似:
Array ( [0] => George [1] => John [2] => Thomas [3] => USA Array ( [0] => James [1] => Adrew [2] => Martin [3] => USA )
windows与linux下兼容问题
今天有问题报过来说linux平台下 fgetcsv处理的有空数据产生起初以为中php版本问题,其实和版本没有关系 在window下开发的同事都没有问题,而自己的本本和服务器上,和使用linux系统的同事 都出现空数据的问题
google一下
设置区域:简体中文,UTF-8编码
复制代码 代码如下:
setlocale(LC_ALL, 'zh_CN.UTF-8');

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.
