1. 表单元素的获取
PHP中获取表单元素的方法较为简单、纯净、易于理解,跟ASP.NET差别很大,我们新建一个页面Index.php用于递交表单:
<form id="formMain" action="Action.php" method="post"> <input name="txtName" type="text" /><br /> <input name="txtAge" type="text" /><br /> <input name="btnSumbit" type="submit" value="Submit" /></form>
注意页面中的text元素用name标识,若写成id则无法获取,在Action.php中获取表单中的值,并打印出来:
Your name: <?php echo $_POST["txtName"]; ?><br />Your age: <?php echo $_POST["txtAge"] ?>
这里使用了$_POST[“”],填入表单元素的name即可获取该元素的值。
$_POST中存放了post方式提交的数据,若为get方式则用$_GET,若不关心来源也可使用$_REQUEST,它其中包含了get、post、cookie和file的数据。

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.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

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.
