i'm stuck in counting new lines PHP

pc · 2012-04-18, 06:05 PM

So I have a $ckeys['keywords'] string, (extract from head meta keywords ) that pretty much looks like this:

word
word
word
word
and so on, depends how many keywords there is.

Now I wrapped every new line into a separate paragraph.

Quote:

<?php echo "" . str_replace("\n", "", $ckeys['keywords']) . ""; ?>

What I would like to have is to have a counter for each new line and use this counter for id='cell1' so I could have id='cell1', id='cell2', id='cell3' ...

Anyone ?

Code:

<?php

$ckeys['keywords'] = array('word1','word2','word3','word4');
$loop = 1;
foreach ($ckeys['keywords'] as $word) {
  printf("<p id='cell%d'>%s</p>\n", $loop, $word);
  $loop++;
}

I think sparky's answer is good but addresses a slightly different question. Perhaps this is closer to the question as posed:

Code:

<?php
$ckeys = array();
$ckeys['keywords'] = <<<EOT
word1
word2
word3
word4
EOT;

foreach (explode("\n", $ckeys['keywords']) as $i => $w) {
    $id = "cell" . ($i+1);
    echo "<p id='$id'>$w</p>\n";
}
?>

You are correct, I assumed that the words were actually in his keywords array.

I already had keywords in array. But it works. Both cd34 and flowersgone without array works. Thanks again.
