Write a PHP function FirstReverse(str) take the str parameter being passed and return the string in reversed order.
For Example: if the input string is "Hello World and Coders" then your program should return the string sredoC dna dlroW olleH.
Solution:
function FirstReverse($str) {
$result='';
for($i=strlen($str)-1; $i>=0; $i--){
$result = $result.$str[$i];
}
return $result;
}
Create PHP function FindIntersection(strArr) read the array of strings stored in strArr which will contain 2 element
the first element will represent a list of comma-separated numbers sorted in ascending order.
the second element will represent a second list of comma-separated numbers.
Your function should return a comma-separated string containing the numbers that occur in elements of strArr in sorted order.
If there is no intersection, return the string false.
Solution:
function FindIntersection($strArr) {
$return ='false';
$array1 = explode(',',$strArr[0]);
$array1= array_map('trim',$array1);
$array2 = explode(',',$strArr[1]);
$array2= array_map('trim',$array2);
$result= array_intersect($array1,$array2);
if(!empty($result)){
$return=implode(',',$result);
}
return $return;
}
Create PHP function LongestWord(sen) take the sen parameter being passed and return the largest word in the string.
If there are two or more words that are the same length, return the first word from the string with that length.
Ignore punctuation and assume sen will not be empty.
function LongestWord($sen) {
$return = '';
//Convert string into Array
$strArrayList = explode(' ', $sen);
$finalArray = array();
///////Filter the words///////////
foreach($strArrayList as $str){
$str = preg_replace("#[[:punct:]]#", "", $str);
$finalArray[] = $str;
}
///////Filter the words///////////
/////////// Get the First word from the string with that length////////
foreach($finalArray as $word){
if(strlen($word)> strlen($return)){
$return = $word;
}
}
/////////// Get the First word from the string with that length////////
return $return;
}
function usernameValidation($str) {
$return = true;
////////////////// 4 to 25 character////////////
if ($return) {
if (!(strlen($str) >= 4 && strlen($str) <= 25)) {
$return = false;
}
}
////////////////// 4 to 25 character////////////
////////////////// Must start with Number ////////////
if ($return) {
$asciiCode = ord($str[0]);
if (!(($asciiCode >= 97 && $asciiCode <= 122) || ($asciiCode >= 65 && $asciiCode <= 90))) {
$return = false;
}
}
////////////////// Must start with Number ////////////
///////////// It can only contain letters, numbers, and the underscore character.///////////
if ($return) {
for ($i = 0; $i < strlen($str); $i++) {
$asciiCode = ord($str[$i]);
if (!( ($asciiCode >= 97 && $asciiCode <= 122) || ($asciiCode >= 65 && $asciiCode <= 90) || ($asciiCode >= 48 && $asciiCode <= 57) || ($asciiCode == 95))) {
$return = false;
break;
}
}
}
///////////// It can only contain letters, numbers, and the underscore character.///////////
///////////It cannot end with an underscore character.///////////
if ($return) {
$asciiCode = ord($str[$i - 1]);
if ($asciiCode == 95) {
$return = false;
}
}
///////////It cannot end with an underscore character.///////////
return $return ? 'true' : 'false';
