Alright sorry for opening posts lately but book is very unclear this time.

 

$zin1[1]="The first thing";

$zin1[2]=" The second thing";

 

print ($zin1).'<br>';

 

This is the curent code offcourse enclosed in php.

 

Now we all know we must do print_r($zin1); in order to see the array.

However mine book does the code like above but if I do that I get an error.

The <br> code won't print when you do print_f so it won't work.

 

What's the best solution in this kind of array?

I know there are different kinds of ways to produce arrays but this is for the study:).

Not really understanding what you are asking to be honest

Best thing I can suggest is to use

echo '<pre>' . print_r($zin1, true) . '</pre>';

That should format it nicely for you

var_dump ?

Unless I'm mistaken echo "<pre>".print_r(array())."</pre>"; would syntax error? You can't echo a print_r() can you? Unless you set the second param to true?

That will indeed giving a syntax error.

I'm not sure but from what I currently know, shouldn't <pre></pre> together in 1 single quote and not like that.

Anyway, I can print it out by using a for each that came later in the chapter.

Maby it was a pre-example to foreach.

 

anyway it's solved:)

Huh? Neither of them would give a syntax error, but not using the second param would mean 1 gets output as well as the array

And as for echoing a print_r, yes you need the true param set (which it is in my example)

Basically my example above prints out the array using print_r but it puts it within <pre> </pre> tags, so that its preformatted. echoing out print_r will not give a syntax error, since it has a return type (and even if it didn't it would return null)

Apologies, I gave an opinion without testing, but we're both kind of wrong:

 

<?php

error_reporting(E_ALL);

$args = array('a','b','c');

echo "<pre>".print_r($args)."</pre>";

?>

 

Outputs

 

Array
(
   [0] => a
   [1] => b
   [2] => c
)
<pre>1</pre>

 

 

<?php

error_reporting(E_ALL);

$args = array('a','b','c');

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

?>

 

Outputs

 

<pre>Array
(
   [0] => a
   [1] => b
   [2] => c
)
</pre>

Sorry but I'm confused now. The second example you gave is exactly what I was saying would be output by my original code and what I was expecting to show, as it formats it nicely in a browser. I don't even know where the whole no second param came from

Hahahaha, I'm such a dick. I wrote all that **** out for no reason. I completely missed your 2nd param. Apologies and +1#s coming your way
