php文件上传获取文件扩展名，运行时会报提示
今天练习文件上传操作，但遇到一个很纠结的事
直接看代码：
文件上传页：index.html
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><br /><html><br /><head><br /><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><br /><title>Insert title here</title><br /></head><br /><body><br /><form method="post" action="test.php" enctype="multipart/form-data"><br />文件<input type="file" name="up1"/><br/><br /><input type="submit" value="上传"/><br /></form><br /></body><br /></html>
文件处理页：test.php
<br />foreach($_FILES as $v){ <br /> $info=pathinfo($v['name']);<br /> //var_dump($info);//查看$info中的信息；<br /> //exit;<br /> //echo $info['extentsion'];//报提示<br /> //exit;<br /> $v['ext']=$info['extension'];//得到文件扩展名<br /> $v['filename']=$info['filename'];//得到文件名<br /> echo $v['ext'];//能得到正确的扩展名<br /> exit; <br />}<br />事情是这样的, 当我echo $info['extension']总会报提示：Notice: Undefined index: extentsion in D:\WW.......
我var_dump($info)时，里面确实有"extension"啊
但是，如上代码所示$v['ext']=$info['extension'];后，我echo $v['ext'];却能得到正确的后缀名
这到底什么情况？？
------解决方案--------------------
//echo $info['extentsion'];//报提示
echo $info['extension'];//报提示
注意拼写啊 少年 怎么可能会有错误呢
PHP and Python: Different Paradigms ExplainedApr 18, 2025 am 12:26 AMPHP 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.
PHP and Python: A Deep Dive into Their HistoryApr 18, 2025 am 12:25 AMPHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.
Choosing Between PHP and Python: A GuideApr 18, 2025 am 12:24 AMPHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.
PHP and Frameworks: Modernizing the LanguageApr 18, 2025 am 12:14 AMPHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2.

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AMPHP 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.
How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AMIn PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
PHP vs. Python: Use Cases and ApplicationsApr 17, 2025 am 12:23 AMPHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
