Help with arrays.

[jacob1986]

I have to declare an array which contains the sentence 'Programming in PHP is fun!' and which also contains the words of the sentence separately.

 

I have the following code but the end sentence has a zero - how do I get rid of that, moreover, how do I put a line break in between the line 'fifth word fun! and Programming in PHP is fun!

<?php $fun = [ 'First Word' => 'Programming', 'Second Word' => 'in', 'Third Word' => 'PHP', 'Fourth Word' => 'is', 'Fifth Word' => 'fun!', 'Programming in PHP is fun!' ]; foreach($fun as $key=>$val) { echo" $key, $val</br>";}  ?>

Output: First Word, ProgrammingSecond Word, inThird Word, PHPFourth Word, isFifth Word, fun!0, Programming in PHP is fun!

You could specify a key for the last element of the array.

$fun = [
 'First Word' => 'Programming',
 'Second Word' => 'in',
 'Third Word' => 'PHP',
 'Fourth Word' => 'is',
 'Fifth Word' => 'fun!',
 'Full Sentence' => 'Programming in PHP is fun!'
];

...how do I put a line break in between the line 'fifth word fun! and Programming in PHP is fun!

 

You could use an if construct to test $key in the foreach loop. Then just insert a line break when the 5th item is found.

Thank-you.

$fun = array(

 'First Word' => 'Programming',

 'Second Word' => 'in',

 'Third Word' => 'PHP',

 'Fourth Word' => 'is',

 'Fifth Word' => 'fun!',

 '' => 'Programming in PHP is fun!'

);


foreach($fun as $key => $val) 

{

	if($key == '')

	{

		echo $val;

	}

	else 

	{

		echo "$key, $val";

	}


	echo '<br />';

}

Just for giggles:

$fun = array(
 'First Word' => 'Programming',
 'Second Word' => 'in',
 'Third Word' => 'PHP',
 'Fourth Word' => 'is',
 'Fifth Word' => 'fun!',
 'Programming in PHP is fun!'
);

foreach($fun as $key => $val) 
{
    if ($val != end(array_values($fun))) {
        echo "$key, ";
    }

    echo "$val<br />";
}

Well, if we're just showing different ways to skin a cat:

 

 

$fun = array(
 'First Word' => 'Programming',
 'Second Word' => 'in',
 'Third Word' => 'PHP',
 'Fourth Word' => 'is',
 'Fifth Word' => 'fun!',
 'Programming in PHP is fun!'
);
 
$fullSentence = array_pop($fun);
foreach($fun as $key => $val) 
{
    echo "$key, $val<br />";
}
echo $fullSentence;

Calling on requinix. 10 characters or less, go!

@hansford, nice, clean answer.

$fun = array(
 'First Word' => 'Programming',
 'Second Word' => 'in',
 'Third Word' => 'PHP',
 'Fourth Word' => 'is',
 'Fifth Word' => 'fun!',
 'Programming in PHP is fun!'
);

foreach($fun as $key => $val) 
{
    if ($val != end(array_values($fun))) {
        echo "$key, ";
    }

    echo "$val<br />";
}

 

 

I get this running your example: Only variables should be passed by reference on line number 14

Interesting take, although it does require that you know that the last element is the one without a key.

Speaking of "Skinning a Cat", lets all head on over here for some fun.

Bummer. Silly PHP.
