Replacing first letter of every new line?

[Bolanb]

What I'm looking for is to check if every new line of a string contains a '=' and then make it bold, while a line break unbolds it. I've been testing a few things out and just can't figure it out. If anyone could help me here, you'll get my <3 and gratitude.

Try this :

 

<?php
$string = '
Some text content content<br />
=content content content content content content<br />
content content content content content content<br />
=content content content content content content<br /> 
content content content content content content ';

//explode your string with new lines.
$string_array = explode('<br />',$string);  // replace  <br />  with \n if you are using normal line break



//now check the array to find out if they contain = at first. 
foreach ($string_array as $line_key => $the_line)
{
     if (substr(trim($the_line),0,1) == '=')
           $string_array[$line_key] = '=<b>'.substr(trim($the_line),1).'</b>'; // replacing the line in array with the bold version.
}

echo implode('<br />',$string_array); // replace  <br />  with \n if you are using normal line break

?>
