Want this question answered?
You could use a function like this:function isPalindrome($string) {$string = strtolower($string);return (strrev($string) == $string) ? true : false;}and then to check a palindrome call an if statement like so:if(isPalindrome($test)) {echo $test.' is a palindrome';}else {echo $test.' is not a palindrome';}
len=0 i=1 echo -n "Enter a String: " read str len=`echo $str | wc -c` len=`expr $len - 1` halfLen=`expr $len / 2` while [ $i -le $halfLen ] do c1=`echo $str|cut -c$i` c2=`echo $str|cut -c$len` if [ $c1 != $c2 ] ; then echo "string is not palindrome" exit fi i=`expr $i + 1` len=`expr $len - 1` done echo "String is Palindrome"
echo will not return output when using parenthesis because echo is not a function like print. echo is a language construct. The benefit to using echo over the print function is speed, plus you can separate data types using comma's rather than periods.Example:echo 'This is a string ' , $variable , ' ending string';is the same (but faster) as:print('This is a sting' . $variable . ' ending string');
" / " and ' / ' However the same starter must end e.g.: echo " '; is wrong echo ' "; is wrong echo " ' "; is right echo ' " '; is right echo " " ' '; is wrong - in this case echo " " . ' '; is right.

With program tac. ExampleVALUE="ABC DEF"REV=$(echo "$VALUE" | tac)echo "$VALUE" "-->" "$REV"
Only if the string is in a loop or there is something at the opposite ends of the string to provide a reflection or echo. If there is an echo then slightly weaker pulses will reflect off of each other near the point of origin.

You can do this: <?php if ( $word === strrev( $word ) ) { echo "The word is a palindrome"; } else { echo "The word is not a palindrome"; }
Which bulb are you trying to change?
See related link. Its not an Echo, but close enough.
