PHP operators are basic elements in programming. Mastering the use of various operators is the key to solving coding problems. In this article, PHP editor Yuzai will explain the types and usage of PHP operators in detail, and lead readers to explore the way to unlock the mystery of the code. Whether it is arithmetic operations, comparison operations or logical operations, they will all be revealed in this article. Let us uncover the mystery of code together, master the essence of operators, and become a master in the world of code!

  • Addition ( ): Add two numbers
  • Subtraction (-): Subtract one number from another number
  • Multiplication (*): Multiply two numbers
  • Division (/): Divide one number by another number
  • Modulo (%): Returns the remainder of the division of two numbers

Comparison operators Comparison operators are used to compare two values. They include:

  • Equal (==): Check whether two values ​​are equal
  • Not equal to (!=): Check whether two values ​​are not equal
  • Less than (
  • Greater than (>): Check whether a value is greater than another value
  • Less than or equal (
  • Greater than or equal to (>=): Checks whether a value is greater than or equal to another value

Logical Operators Logical operators are used to connect and manipulate Boolean values ​​(true or false). They include:

  • With (&&): If both values ​​are true, return true, otherwise return false
  • or (||): Returns true if either or both values ​​are true, otherwise returns false
  • Not (!): Change true value to false value and vice versa

Assignment operator Assignment operator is used to assign a value to a variable. They include:

  • Assignment (=): assign a value to a variable
  • Additional assignment (=): Add a value to a variable
  • Subtractive assignment (-=): Subtract a value from a variable
  • Multiplicative assignment (*=): Multiply a variable by its value
  • Division assignment (/=): Divide a variable by its value
  • Modulo assignment (%=): Divide a variable by its value and return the remainder

Increment and decrement operators The increment ( ) and decrement (--) operators are used to increase or decrease the value of a variable by 1. They can be used as prefix or postfix operators:

  • Prefix increment ($a): Increment the value of a variable before getting its value
  • Suffix increment ($a): Increase the value of the variable after getting the variable value

Bitwise operators Bitwise operators are used to operate on binary bits. They include:

  • Bitwise AND (&): AND each bit of two binary numbers
  • Bitwise OR (|): OR each bit of two binary numbers
  • Bitwise XOR (^): XOR each bit of two binary numbers
  • Bitwise NOT (~): flip each bit of a binary number

String operators StringOperators are used to concatenate and manipulate strings. They include:

  • Concatenate (.): concatenate two strings
  • Equality (==): Check whether two strings are equal
  • Not equal (!=): Check whether two strings are not equal

Special operators PHP also provides some special operators, such as:

  • Null value merging character (??): Return the first non-null value
  • Parsing operator (): Parses string into code
  • Range operator (...): Create a sequence or array

in conclusion Mastering the php operators is crucial to writing efficient and maintainable code. By understanding and effectively using operators, developers can simplify tasks such as calculations, comparisons, assignments, and string manipulations to create powerful and easy-to-read code.

mPDF

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),
