Reverse String

Reverse String

A string can be reversed either using strrev() function or simple PHP code.

For example, on reversing JAVATPOINT it will become TNIOPTAVAJ.

Logic:

• Assign the string to a variable.
• Calculate length of the string.
• Declare variable to hold reverse string.
• Run for loop.
• Concatenate string inside for loop.
• Display reversed string.

Reverse String using strrev() function

A reverse string program using strrev() function is shown.

Example:

<?php  
$string = "JAVATPOINT";  
echo "Reverse string of $string is " .strrev ( $string );  
?>  

<?php  
$string = "JAVATPOINT";  
$length = strlen($string);  
for ($i=($length-1) ; $i >= 0 ; $i--)   
{  
  echo $string[$i];  
}  
?>
