strrev(): PHP String Reverse
echo strrev('plus2net'); //ten2sulp
Syntax
echo strrev($input_string);
$input_string
: Input string to be reversed
Output is the string after reversing input string.
The original ( input string ) remains same.
We can reverse any string by applying strrev() function.
Here is the code
$st="This is a test";
echo "The string = ".$st."<br>";
$st=strrev($st);
echo "The new string after applying the strrev function = ".$st."<br>";
Printing the string in reverse without using strrev() function.
Here is the code.
<?Php
$st="Hello world";
//echo $st[4];
$length=strlen($st);
for($i=$length-1;$i>=0;$i--){
echo $st[$i];
}
?>
Output is here
dlrow olleH
This function support utf-8 encoding and does not work with unicode strings.
