I am doing an assignment on how to take a string of text separated by commas and reverse the individual words and return the words in the same order.
This code does that but it is not returning it as a string for some reason and i do not understand.
<?php
function bassAckwards($input)
{
// YOUR CODE HERE
$commas = substr_count($input, ",");
$NumWords = ($commas + 1);
$words = array($input);
for($x=0;$x<$NumWords;$x++)
{
$answer = array(strrev($words[$x]));
$answer = implode(",",$answer);
print $answer;
}
}
?>
$reversedWords = array();
// Explode by commas
$words = explode(',', $input);
foreach ($word in $words) {
// For each word
// Stack it, reversed, in the new array $reversedWords
$reversedWords[] = strrev($word);
}
// Implode by commas
$output = implode(',', $reversedWords);
print $output;
function bassAckwards($str){
$words = explode(',', $str);
$reversedWords = array_map('strrev', $words);
return implode(',', $reversedWords);
}
var_dump(bassAckwards('foo,bar,baz')); // string(11) "oof,rab,zab"
Save yourself some headaches and use the built-it functions.
explodearray_map & strrevstrrev (string reverse) on every element of the array with array_map and return the [modified] array back.implode
