PHP outputs four functions to the browser, and the php browser outputs the functions.
Copy codeThe Code is as follows:
<! DOCTYPE unspecified PUBLIC "-// W3C // dtd html 4.01 Transitional //" "http://www.w3.org/TR/html4/loose.dtd">
<Html>
<Body>
<? Php
/*
* 0x01: print () Statement
* Int print (arguments );
* The print () Statement outputs the data passed in to the browser.
*/
Print ("<p> I love PHP !!! </P> ");
Print "<p> I love PHP !!! </P> ";
?>
<? Php
/*
* 0x02: echo () Statement, which has the same function as the print () function.
* All data is output to the browser.
* The output efficiency of the echo () function is slightly better than that of the print () function, because echo does not return results.
*/
Echo "<p> I love PHP !!! </P> ";
$ Required Ge = "Java ";
Echo "<p> I love $ sharege !!! </P> ";
?>
<? Php
/*
* 0x03: printf () Statement
* If you want to output a hybrid product composed of any static text and dynamic information stored in one or more variables, the printf () function is ideal.
* The printf () function divides static data and dynamic data into two parts, in the form:
* Integer printf (string format [, mixed args]);
*/
Printf ("<p> I love % s !!! </P> "," C #");
/*
* In the preceding example, % s is a placeholder. Common Placeholders are listed below.
* Type description
* % B indicates that the parameter is regarded as an integer and displayed as a binary number.
* % C considers the parameter as an integer and displays it as an ASCII character.
* % D the parameter is regarded as an integer and displayed as a signed decimal number.
* % F considers the parameter as a floating point number and displays it as a floating point number.
* % O considers the parameter as an integer and displays it as an eight-digit number.
* % S: the parameter is considered a string and displayed as a string.
* % U is regarded as an integer and displayed as an unsigned integer.
* % X indicates an integer that is regarded as a lowercase hexadecimal number.
* % X indicates an integer that is an uppercase hexadecimal number.
*/
$ Num = 1024;
Printf ("<p> % B: % c: % d: % f: % o: % s: % u: % x: % X </p> ", $ num, $ num );
?>
<? Php
/*
* 0x04: sprintf () Statement
* The sprintf () function is the same as the printf function, but it assigns the output value to a string instead of directly outputting it to the browser.
* This function is very useful. For example, you can format a string containing dynamic output and combine it with the placeholder above to perform hexadecimal conversion. The form is:
* String sprintf (string format [, mixed args]);

$ Cost = sprintf ("$ %. 2f", 43.2); // $ cost = $43.20
