I haven’t used Smarty for a project for a long time. Today I suddenly have to change some things in my website, because my website was made with the smarty template engine a long time ago. After changing some parts, I feel that it is not enough. I searched the Internet for answers. It seems that I am already unfamiliar with smarty, which I haven’t seen for a long time. I need to catch up on it quickly. Let’s briefly summarize the logical operation symbols of Smarty templates for future use.
eq equal : equal
neq not equal:not equal to
gt greater than: greater than
lt less than: less than
lte less than or equal:less than or equal
gte great than or equal:greater than or equal
is even: It is an even number
is odd: It is an odd number
is not even: not an even number
is not odd is not an odd number
not: 🎜>
mod: Find the modulus and remainder
div by: quilt. . . except
&& and : And
|| or : or
is [not] div by Whether it can be divided by a certain number, for example: {if $smarty.get.age is div by 3}...{/if}
is [not] even Whether it is an even number, for example: $a is [not] even by $b, that is ($a / $b) % 2 == 0,
is [not] odd Whether it is odd, for example: $a is not odd by $b, that is ($a / $b) % 2 != 0
{if $_global_password!==''} is to judge whether the variables are not equal to empty....
The if statement and if in Smarty must appear in pairs with /if. Else and elseif clauses can be used.
Use eq, ne, neq, gt, lt, lte, le, gte, ge, is even, is odd, is not even, is not odd, not, mod, div by, even by, odd by in the template , ==, !=, >, = these logical operation symbols must be separated from variables or constants by spaces. Articles you may be interested in

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

In PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.

Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

SplFixedArray is a fixed-size array in PHP, suitable for scenarios where high performance and low memory usage are required. 1) It needs to specify the size when creating to avoid the overhead caused by dynamic adjustment. 2) Based on C language array, directly operates memory and fast access speed. 3) Suitable for large-scale data processing and memory-sensitive environments, but it needs to be used with caution because its size is fixed.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

In JavaScript, you can use NullCoalescingOperator(??) and NullCoalescingAssignmentOperator(??=). 1.??Returns the first non-null or non-undefined operand. 2.??= Assign the variable to the value of the right operand, but only if the variable is null or undefined. These operators simplify code logic, improve readability and performance.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
