I am trying to do the following and having some difficulty. I am trying to echo the words in the array as the key along with the total times the word appears in the string. Any advisewould be great.

 

 

 

Part 1: Write a function countWords($str) that takes any string of characters and finds the

number of times each word occurs. You should ignore the distinction between capital and

lowercase letters, and do not have to worry about dealing with characters that are not letters.

Hint: Create an associative array mapping word keys to the number of times they occur. You will

need to look at PHP's string functions to split a sentence into words.

Hint 2: The print_r($array_name) function is useful for examining the contents of an

array.

 

My code:

<?php

// my string
$str = "My name is dale and i am a programmer learning php a programmer am i dale";

// my string to lower case
$str = strtolower($str);

// split string into words and put into an array
$words = explode(' ', $str);

// counts values of array
$counts = array_count_values($words); 

foreach ($counts as $key => $value) {
	echo $value;
}

?>

// counts values of array
$counts = array_count_values($words); 

foreach ($counts as $key => $value) {
	echo $value;
}

?>

 

Now, explode turns your data into an array splitting the parts up by using the space as a splitter, so you don't need array counts to get the data back.

 

<?php

// my string
$str = "My name is dale and i am a programmer learning php a programmer am i dale";

// my string to lower case
$str = strtolower($str);

// split string into words and put into an array
$words = explode(' ', $str);

foreach ($words AS $key => $value) {
	echo $value.'<br />';
}


//Counts How many parts are in this array?
echo 'There are '.count($words).' words in this array!';

?>

Brilliant so the count() function counts the total amount of words in a string. Is there a way to count how many of each words there are? For example the word 'programmer' count as twice. Is there a way to echo in a nicer format print_r($counts)?

 

$str = "My name is dale and i am a programmer learning php a programmer am i dale";
$str = strtolower($str);
$words = explode(' ', $str);
$counts = array_count_values($words); 

print_r($counts);

Add me up on skype: nitrophysix, Ill help you for free

 

The count is counting how many parts there are in an array.

Is this what you are looking for

<?php


	// my string

	$str = "My name is dale and i am a programmer learning php a programmer am i dale";


	// my string to lower case

	$str = strtolower($str);


	// split string into words and put into an array

	$words = explode(' ', $str);


	$count = array();


	// Loop throgh the resulys and start counting

	foreach ($words as $value) {


		// Check to see if the word exists if so increment the count if not start the count at 1

		if (isset($count[$value])) {

			$count[$value]++;

		} else {

			$count[$value] = 1;

		}

	}

	// Display the results

	echo "<pre>".print_r($count, true)."</pre>";


?>

Output

Array
(
    [my] => 1
    [name] => 1
    [is] => 1
    [dale] => 2
    [and] => 1
    [i] => 2
    [am] => 2
    [a] => 2
    [programmer] => 2
    [learning] => 1
    [php] => 1
)

Sorry for the double post the bb coded F'ed up the code formatting

you could use this solution

 

<?php


// my string
$str = strtolower("My name is dale and i am a programmer learning php a programmer am i dale");

// split string into words and put into an array
$words = explode(' ', $str);

$vals = array_count_values($words);


echo "<pre>";
print_r($vals);
echo "</pre>";


foreach($vals as $k => $v)
{
  echo "<b>".$k. "</b> occurs " .$v." times in this sentence <br/>";
}




?>

 

 

it is self explanatory i hope

 

this script will return:

 

Array
(
[my] => 1
[name] => 1
[is] => 1
[dale] => 2
[and] => 1
=> 2
[am] => 2
[a] => 2
[programmer] => 2
[learning] => 1

 => 1
)
my occurs 1 times in this sentence 
name occurs 1 times in this sentence 
is occurs 1 times in this sentence 
dale occurs 2 times in this sentence 
and occurs 1 times in this sentence 
i occurs 2 times in this sentence 
am occurs 2 times in this sentence 
a occurs 2 times in this sentence 
programmer occurs 2 times in this sentence 
learning occurs 1 times in this sentence 
php occurs 1 times in this sentence

thats fantastic everyone, really appreciate it. i will study the code and put it to practice in another scenario to learn from. Thanks again
