Well,

I've some texts like this below:

< Jens > is my name. I play < Football >. I saw < Steffy > Yesterday. Yeah, We will be < Together > For sure.

And I just want all the texts between '<' & '>' (including <>) to be bold programmatically using Regular Expression (Preferably) or any other method. This is a kind of Find & Replace. So after the operation texts should be :

< Jens > is my name. I play < Football >. I saw < Steffy > Yesterday. Yeah, We will be < Together > For sure.

Use preg_replace_callback():

<?php
// header('Content-Type: text/plain; charset=utf-8');

$test = <<<TXT
< Jens > is my name. I play < Football >.
I saw < Steffy > Yesterday. Yeah, We will be < Together > For sure.
TXT;

$result = preg_replace_callback(
    '/<[^>]+>/',
    function($matches){
        return '<b>' . htmlspecialchars($matches[0]) . '</b>';
    },
    $test
);

print_r($result);
?>

Output:

< Jens > is my name. I play < Football >. I saw < Steffy > Yesterday. Yeah, We will be < Together > For sure.

Why need a callback? Wouldn't preg_replace and as replacement '<b>\0</b>' be convenient? –  Jonny 5 Aug 27 at 10:44
    
It gets rendered in browser just like this : <b>< Jens ></b> is my name. I play <b>< Football ></b>. I saw <b>< Steffy ></b> Yesterday. Yeah, We will be <b>< Together ></b> For sure. No bold! –  Maxin Bits Aug 27 at 10:45
    
@Jonny5 I do have a strong feeling, that after this "Find & Replace" OP might want to have more control over situation. –  HAL9000 Aug 27 at 10:45
    
@MaxinBits remove header() string –  HAL9000 Aug 27 at 10:46
    
ThankYou..Cheers..:) –  Maxin Bits Aug 27 at 10:51

You can use this preg_replace:

$repl = preg_replace('/(<[^>]*>)/', '<b>$1</b>', $str);

<b>< Jens ></b> is my name. I play <b>< Football ></b>. I saw <b>< Steffy ></b> Yesterday. Yeah, We will be <b>< Together ></b> For sure.

\b or <b>? I'm on browser not in CLI. –  Maxin Bits Aug 27 at 10:47
    
Yes it should be <b>, corrected in code now. –  anubhava Aug 27 at 10:51
    
ThankYou..:) (<b>$1<\b> --> <b>$1</b>) –  Maxin Bits Aug 27 at 10:56
    
Yes that's correct, my HTML skills are pretty poor :( –  anubhava Aug 27 at 10:58
