[RESOLVED] str_replace .... again!

[azurian]

Visitors to my site may search a database by entering a string. When they see the result, I want to be able to highlight the search term they used. This is what I have tried:

$Message=str_replace('$keyword','<b>$keyword</b>',$Message);

To put it another way, every time the user's keyword appears, I want it to be highlighted.

Any ideas would be appreciated.

I think you need to refer to your mysql result more?

 $result = $row['sql_result'];
 $Message=str_replace('$keyword','<b>$keyword</b>',$result);

Thanks for that, but I hhave already done that - sorry, didn't make it clear.

$Message=$row[Message];
$Message=str_replace('$keyword','<b>$keyword</b>',$Message);

I think one of the difficulties you were having was in your string-replacement statment, you were utilizing single-quotes. so php was literally looking for: $keyword. One fix would be to use double-quotes, or to conccatenate.

Also, I believe <b> tags should be replaced with <strong> tags:

<?php
// keyword
$keyword = 'php';

// sample message
$message = 'php is a cool scripting language.';

// perform string replacement
$message = str_replace($keyword, '<strong>' . $keyword . '</strong>', $message);

// echo results
echo $message;
?>

Many thanks Rodney. I have now sorted the problem with your help.

You were absolutely right about the double quotes.

The bold tags work fine and I found there was no need to concetenate the replacement string. The line now reads:

$Message=str_replace("$keyword","<b>$keyword</b>",$Message);  

Thanks again 😃
