Q.Write a PHP script for the following: Design a form to accept two strings. Compare the two strings using both methods (= = operator & strcmp function). Append second string to the first string. Accept the position from the user; from where the characters from the first string are reversed. (Use radio buttons)
HTML File:
<html>
<head><title> .html</title></head>
<body bgcolor="violet" >
<form action="ass1c2.php" method="post">
<pre>
Enter first string ::<input type="text" name="str1">
Enter second string::<input type="text" name="str2">
Enter position::<input type='text' name="pos">
<input type="radio" name="ch" value=1>compare
<input type="radio" name="ch" value=2>with datatype
<input type="radio" name="ch" value=3>append.
<input type="radio" name="ch" value=4>possition for reverse.
<input type="submit" value="check"> <input type="reset" value="cancel">
</pre>
</form>
</body>
</html>
PHP Function:
NOTE: PHP function is saved as "ass1c2.php"
<?php
$str1=$_POST['str1'];
$str2=$_POST['str2'];
$pos=$_POST['pos'];
$ch=$_POST['ch'];
echo"First string :: $str1.<br><br>";
echo "Second string::$str2.<br><br>";
echo"position for reverse::$pos.<br><br>";
echo"choice is::$ch.<br><br>";
switch($ch)
{
case 1:
if($str1==$str2)
echo"Both string are equal.<br>";
else
echo"Both string are not equal.<br>";
break;
case 2:
if($str1===$str2)
echo"Both are exat equal.<BR>";
else
echo"Both are not equal.<BR>";
break;
case 3:
echo"After appending::";
echo "$str1"."$str2";
echo"<br>";
break;
case 4: $len=strlen($str1)-$pos;
$s=substr($str1,$pos,$len);
$str4=strrev($s);
echo "After reverse::$str4.<br>";
break;
}
?>
Output:
