Is it possible to include an element inside a foreach and indicate that it should not be repeated in each result?

January 30, 2022

I read the rest documentation; and to continue; but it doesn’t seem to work with this requirement.

<?php  
$colors = array("red", "green", "blue", "yellow"); 

foreach ($colors as $value) {
?><p>TITLE</p><?php
 echo "$value <br>";
}
?>

Output:

TITLE
red

TITLE
green

TITLE
blue

TITLE
yellow

I thought that with break or continue it would be possible but it seems that it is not what I need or I did not understand it exactly.

I need (including the title inside the foreach to avoid longer code like an if condition):

TITLE
red

green

blue

yellow

Do you know any correct way to achieve this? Thanks!

Even with the comments on the question, it’s still not clear to me why you wouldn’t just gate this all with a simple if. If you insist on continuing with this design, you can check the $index of the current item you’re iterating on in the foreach loop and if it’s the first one, echo TITLE along with it:

<?php  
$colors = array("red", "green", "blue", "yellow"); 

foreach ($colors as $key=>$value) {
  if ($key === 0) echo "<p>TITLE</p>";
  echo "$value <br>";
}
?>

In my personal opinion, however, it would be much more readable if you simply gated the entire block here:

<?php  
$colors = array("red", "green", "blue", "yellow"); 

if (count($colors) > 0) {
  echo "<p>TITLE</p>";
  foreach ($colors as $value) {
    echo "$value <br>";
  }
}
?>
