Example 2

In the below PHP code we will use the stripcslashes() function and show you how it processes octal escape sequences. Here, '\040' is representing a space.

<?php
   // Mention the string input here
   $input = "Tutorials\\040Point";
   $output = stripcslashes($input);

   // Print the result
   echo $output;

Now the below code uses stripcslashes() function and shows unescaping hexadecimal representations in a string. Here '\x57' is the hexadecimal representation of 'W'.

<?php
   // Mention the string here
   $input = "Hex\\x57orld";
   $output = stripcslashes($input);

   // Print the result
   echo $output; 
?> 

Output

<?php
   $input = "Line1\\nLine2\\040with\\x21";
   $output = stripcslashes($input);
   echo $output; 
?> 

Output

Following is the output of the above code −
