Displaying a png image through a PHP script

$fileName = "images/no_image.png"; header("Content-type: image/png"); readfile($fileName); exit;

Convert unix timestamp to PHP

Leave a reply

The problem:
You are getting a unix timestamp, and you want to format it with PHP, the following is a sample unix timestamp:

1342259667654             // 2012-14-07 11:54:27 - the correct time

1	1342259667654 // 2012-14-07 11:54:27 - the correct time

If you were to use the date() function on this you would get:

echo date("Y-m-d H:i:s", 1342259667654);     //1904-07-24 10:22:47

1	echo date("Y-m-d H:i:s", 1342259667654); //1904-07-24 10:22:47

which is incorrect. The issue is that the unix timestamp works with miliseconds, while PHP can only handle seconds. In order to correctly format the timestamp, you should divide it by 1000 such as:

echo date("Y-m-d H:i:s", (1342259667654/1000));    //correct time

1	echo date("Y-m-d H:i:s", (1342259667654/1000)); //correct time

and Voila you have the correct time.

PHP get the last character of a string

You can get the last char by using the subsrt() function.

$rest = substr("abcdef", -1);    // returns "f"
?>

<?php

$rest = substr("abcdef", -1); // returns "f"

How to find number of days between two dates using php

     $your_date = strtotime("2010-01-01");
     $datediff = $now - $your_date;
     echo floor($datediff/(60*60*24));

?>

$datediff = $now - $your_date;

echo floor($datediff/(60*60*24));

Create MySQL function example

Leave a reply

Scenario:

This is a simple tutorial on how to create a MySQL function.
For example, I need a MySQL function that will take in 2 integer input parameters and return a tinyint value to user.

Solution:

Here is the sample function code:

DELIMITER $$

DROP FUNCTION IF EXISTS `sampleFunc1`$$

CREATE FUNCTION `sampleFunc1`(
			a INT, 
			b INT
		) RETURNS TINYINT(1)
    DETERMINISTIC
BEGIN
	-- Function logic here
	DECLARE run TINYINT DEFAULT 0;
	IF (a+b) > 100 THEN
		SET run = 1;
	ELSE
		SET run = 2;
	END IF;
	RETURN run;
    END$$

DELIMITER ;

DELIMITER $$

DROP FUNCTION IF EXISTS `sampleFunc1`$$

CREATE FUNCTION `sampleFunc1`(

a INT,

b INT

) RETURNS TINYINT(1)

DETERMINISTIC

BEGIN

-- Function logic here

DECLARE run TINYINT DEFAULT 0;

IF (a+b) > 100 THEN

SET run = 1;

ELSE

SET run = 2;

END IF;

RETURN run;

END$$

DELIMITER ;

Output:

Check if a line is valid or not in Java

2 Replies

I had the following code:

VALID LINES;
/**/ some code
*/ some code   /** dsfsdkf sd**/

NOT VALID LINES;
/**/ //some code
*/ /***/ //somecode

VALID LINES;

/**/ some code

*/ some code /** dsfsdkf sd**/

NOT VALID LINES;

/**/ //some code

*/ /***/ //somecode

So basically if there is a line of code outside a comment it is valid, otherwise not.

Note:
For */ I assume that the /* has been opened some lines before.

The following snippet will get only valid lines of code:

import java.io.*;

class Test {

    public static void main(String[] args) throws IOException {
        StringBuffer buf = new StringBuffer();
        BufferedReader r = new BufferedReader(new FileReader("src/Test.java"));

        final String nl = System.getProperty("line.separator");
        String line;
        while (null != (line = r.readLine()))
            buf.append(line).append(nl);

        for (String code : buf.toString().split("(?ms)/\\*.*?\\*/|//[^\\n]*"))
            System.out.println(code);
    }
}

import java.io.*;

class Test {

public static void main(String[] args) throws IOException {

StringBuffer buf = new StringBuffer();

BufferedReader r = new BufferedReader(new FileReader("src/Test.java"));

final String nl = System.getProperty("line.separator");

String line;

while (null != (line = r.readLine()))

buf.append(line).append(nl);

for (String code : buf.toString().split("(?ms)/\\*.*?\\*/|//[^\\n]*"))

System.out.println(code);

}
