PHP echo/print change text font colour on text from array

Question

Hi I have small problem with changing colour of font from array, printing things works fine.

<?php print $Pobierz_wsyzstkie [1]; ?>
<?php echo $Pobierz_wsyzstkie [3]; ?>

This works fine, write what they should. But if i try to colour the array output with code like this:

   <?php echo "<span style='color:blue;'>$Pobierz_wsyzstkie 
   [3]</span>"; ?>

I get coloured text but is not text from array, this shows "Array [3]".

Answer 1

Write it like this (note the quotes and dots to separate and connect PHP and HTML string output):

<?php echo "<span style='color:blue;'>".$Pobierz_wsyzstkie[3]."</span>"; ?>

Answer 2

You have a space between your variable and your square brackets. This is the direct cause of the issue. Also, correctly concatenate your variables within your string.

Here;

<?php 
   echo "<span style='color:blue;'>".$Pobierz_wsyzstkie[3]."</span>";
?>

Best Practises :

• The PHP open and close tags should be on their own lines.
• Array references (keys) should not have a space between them and their array variable name ($Pobierz_wsyzstkie[3] not "$Pobierz_wsyzstkie [3]")
• Learn about the correct PHP String Concatenation.
• PHP variables ($Pobierz_wsyzstkie) should start with a lower case letter.
• CSS styles should not be inline but instead should be in their own CSS file.
