This code can be used to show some random quotes or random links every time the page is loaded or refreshed.
$quote = array(
1 => "Random Quote 1",
2 => "This is sample quote 2",
3 => "check http://programming-in-php.blogspot.com",
4 => "it really works",
5 => "wooooooooooooooooooooow",
6 => "I am on twitter"
);
$randnum = rand(1,6);
echo "Random Quote - $quote[$randnum]";
?>
If it is needed to Split string in php and then use those splitted values for some processing in that case you can use this script which Splits string with php explode function and prints array.
$string = "Contents of the string can be splitted by explode function.";
$splitted = explode(" ",$string);
$cnt = count($splitted);
$i=0;
while($cnt > $i)
{
echo "$splitted[$i]";
echo "\n";
$i++;
}
?>
Caution: While using Javascript and an alert message is fired using a timer, then keep the timer for atleast 10 seconds, i.e. 10000. Else, the system will hang. I experienced it recently.
Please note.

This is very simple and useful php script if you want to display some random quotes each time a page is visited or refreshed.
$quote = array(
1 => "Random Quote 1",
2 => "This is sample quote 2",
3 => "check http://programming-in-php.blogspot.com",
4 => "it really works",
5 => "wooooooooooooooooooooow",
6 => "I am on twitter"
);
$randnum = rand(1,6);
echo "Random Quote - $quote[$randnum]";
?>
Sometimes it is required to show the contents of some text file to the web page. So we can change those contents easily without any problem.
First we will create a simple text file, with some contents.
name it as "test.txt"
These contents are saved in test.txt file.
I am showing you the contents of some text file.
Its very useful to show the contents of the text file in a browser.
$file1="test.txt";
if (file_exists($file1))
{
$file = fopen("test.txt", "r");
while (!feof($file))
{
$display = fgets($file, filesize("test.txt"));
echo $display . "
";
}
fclose($file);
}
else
{
echo "Error occured ! ! ! Try again or report it to us";
}
?>
?>
This is a small program which generates a factorial of a number in php.
function doFactorial ($x) {
if ($x <= 1)
return 1;
else
return ($x * doFactorial ($x-1));
}
while($i<100)
{
print $i." --> ".(doFactorial ($i)) . "
";
$i++;
}
?>
sometimes it is required to restrict the length of the textarea so that user should not enter characters beyond a certain limit.
For this we can make use of this simple javascript.
First we will create a 2 textarea.
function restrict(mytextarea) {
var maxlength = 15; // specify the maximum length
if (mytextarea.value.length > maxlength)
mytextarea.value = mytextarea.value.substring(0,maxlength);
} // -->
Today we will be seeing a small easy function to generate a password of specified length.
For this we will be creating a function called "genpwd()"
Now this function is ready, now we want to display the generated password of our specified length.
For this we will print the function value, specifying the length of the password to be generated.
The full working sample example is here, you can copy and paste this code to try it out. It will generate a random string everytime you refresh the page.
function genpwd($cnt)
{
// characters to be included for randomization, here you can add or delete the characters
$pwd = str_shuffle('abcefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890@#%$*');
// here specify the 2nd parameter as start position, it can be anything, default 0
return substr($pwd,0,$cnt);
}
echo genpwd(10); // specify the length of the generated password
function passwordGenerator($length = null)
{
$pass = md5(time());
if($length != null) {
$pass = substr($pass, 0, $length);
}
return $pass;
}
echo passwordGenerator(6);
function generate_password($len = 8) {
$chars = str_split('0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@#');
$pwd = '';
for($i=0; $i < $len; $i++)
$pwd .= $chars[rand(1, $sizeof($chars)) -1];
return $pwd;
}
Sometimes we require that when the users click on a textarea at that time all the text should get selected.
This can be done with a small javascript.
Hi guys,
Hello,
Today we will be seeing a javascript which will help us to show how many characters are remaining for a textbox or textarea,As soon as the user starts typing in a textbox or textarea, then we will show how many characters are remaining for entering into the textbox.
Here we are creating a simple textbox, and we are specifying the "maxlength" of the textbox to 20.
Here is a way to convert numbers to words (upto one lakh). It can be extended as per your requirement as well. This is useful for billing etc. Note that only one parameter should be input, and not both. The second parameter is used only for some internal recursive calling.
