Php is embedded in html and runs as follows:
$ A = "Hello ";
$ B = "php ";
Echo $ a. $ B;
?>
Note:
Define a variable with the $ variable name, such as $ a $ B. When referencing this variable, use the $ variable name;
After each statement is complete, add the ';' sign to end;
Echo is used for output;
$ A. $ B; '.' is used to connect two strings.
The running result of the above program is:
Hello, PHP!
Output php information:
Phpinfo ();
?>
If statement in php:
$ A = 10;
$ B = 1;
If ($ a = $ B ){
Echo "a = B ";
}
?>
Output result:
A = B
