php生成的csv, 无法完整显示带前导0的数字

Jun 23, 2016 pm 01:04 PM

php生成csv文件时,如果数字的第一位为0的话,显示时则不会显示第一个0

可以在php中做特殊处理,使得生成的csv在显示时能显示出第一个0

有两种方法可以实现:

1、给数字加上引号,并且在引号前面再加上个等号,如数字0555,,则生成时为="0555"

2、在数字前面加上制表符,如是数字0555,则生成时为\t0555

$arr    = array (    array ('111', 2222, '0555'),    array ('222', 3333, '0666'));$fp    = fopen('t.csv', 'w');foreach ($arr as $row) {    fputcsv($fp, array_map('h', $row));}fclose($fp);function h($v) {    if (($v{0} == '0') && is_numeric($v)) {        $v    = '="' . $v . '"';    //第一种方式        //$v   = "\t{$v}";    //第二种方式    }    return $v;}

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
