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()"

<br />function genpwd($cnt)<br />{<br />// characters to be included for randomization, here you can add or delete the characters <br /> <br /><br /> $pwd = str_shuffle('abcefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890@#%$*');<br /><br />// here specify the 2nd parameter as start position, it can be anything, default 0 <br /><br /><br /> return substr($pwd,0,$cnt); <br />}<br />

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.

<br />echo genpwd(10);<br />

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.

<br />   some text here <br />   some text here<br />

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.
<br /><?php<br />function ConvertToWords($n, $followup='')<br />{<br /> if($n==0)<br /> {<br /> if($followup=='no')<br /> {<br /> return "";<br /> exit();<br /> }<br /> else<br /> {<br /> return "zero";<br /> exit();<br /> }<br /> }<br /> switch($n)<br /> {<br /> case 1: return "one"; break;<br /> case 2: return "two"; break;<br /> case 3: return "three"; break;<br /> case 4: return "four"; break;<br /> case 5: return "five"; break;<br /> case 6: return "six"; break;<br /> case 7: return "seven"; break;<br /> case 8: return "eight"; break;<br /> case 9: return "nine"; break;<br /> case 10: return "ten"; break;<br /> case 11: return "eleven"; break;<br /> case 12: return "twelve"; break;<br /> case 13: return "thirteen"; break;<br /> case 14: return "fourteen"; break;<br /> case 15: return "fifteen"; break;<br /> case 16: return "sixteen"; break;<br /> case 17: return "seventeen"; break;<br /> case 18: return "eighteen"; break;<br /> case 19: return "nineteen"; break;<br /> case 20: return "twenty"; break;<br /> case 30: return "thirty"; break;<br /> case 40: return "forty"; break;<br /> case 50: return "fifty"; break;<br /> case 60: return "sixty"; break;<br /> case 70: return "seventy"; break;<br /> case 80: return "eighty"; break;<br /> case 90: return "ninety"; break;<br /> case 100: return "one hundred"; break;<br /> case 1000: return "one thousand"; break;<br /> case 100000: return "one lakh"; break;<br /> default:<br /> {<br /> if($n<100)<br /> {<br /> return ConvertToWords(floor($n/10)*10, 'no')."-".ConvertToWords($n%10, 'no'); break;<br /> }<br /> elseif($n<1000)<br /> {<br /> return ConvertToWords(floor($n/100), 'no')." hundred ".ConvertToWords($n%100, 'no'); break;<br /> }<br /> elseif($n<100000)<br /> {<br /> return ConvertToWords(floor($n/1000), 'no')." thousand ".ConvertToWords($n%1000, 'no'); break;<br /> }<br /> elseif($n<10000000)<br /> {<br /> return ConvertToWords(floor($n/100000), 'no')." lakh ".ConvertToWords($n%100000, 'no'); break;<br /> }<br /> else<br /> {<br /> return "Something else"; break;<br /> }<br /> }<br /> }<br />}<br />?><br />
