wordwrap, chunk_split or something else can help me?

Hi all,
How to break line of long string including inside html code?

Example
I have a long string of letters AAAAAAAACCCCCCCCC and they was formated with html code.

Expand|Select|Wrap|Line Numbers

AAAAAAAAACCCCCCCCCC

How to break line each 4 letters (still keep the color of these letters). I was used wordwrap, chunk_split but failed. Please help me, thanks!

Hey.

You could just go through the string manually and add line-breaks at the appropriate positions. You would just have to loop through each character in the string, detect whether or not it is inside a HTML tag, and if it is not, count it. And then you would just add a " " every time the counter reaches 4.

For example:

Expand|Select|Wrap|Line Numbers

 <?php

$input = "<font color=magenta>AAAAAAAAA</font><font color=red>CCCCCCCCCC</font>";

$output = '';
 
$tag_open = false;

$letter_counter = 0;

$input_length = strlen($input);
 
for($i = 0; $i < $input_length; ++$i) 

{

    // Check if the current letter is a opening or closing tag.

    if($input[$i] == ">" || $input[$i] == "<") 

    {

        // It is! Change the $open boolean so that the next

        // loop knows that a tag open/close was detected.

        $tag_open = !$tag_open;

    }

    else 

    {

        // Check if the current letter is inside a tag.

        if(!$tag_open)

        {

            // Check if the current character count is at 4

            if($letter_counter == 4)

            {

                // Add a line-break and reset the count

                $output .= "<br>";

                $letter_counter = 0;

            }

            // Add the current letter to the cycle count.

            ++$letter_counter;

        }

    }
 
    // Add the current letter to the output string.

    $output .= $input[$i];

}
 
echo $output;

?>

Prints:

Expand|Select|Wrap|Line Numbers

 <font color=magenta>AAAA<br>AAAA<br>A</font><font color=red>CCC<br>CCCC<br>CCC</font>
 

And also, you should try to avoid using old HTML tags like  to format your pages. It's generally better to use CSS.

Expand|Select|Wrap|Line Numbers

 
# Instead of doing:

<font color="red">ABCD</font>

# Do:

<span style="color: red;">ABCD</span>

Or better yet:

Expand|Select|Wrap|Line Numbers

 <!DOCTYPE html>

<head>

    <title>CSS Example</title>

    <style type="text/css">

        span.red {

            color: red;

        }

    </style>

</head>

<body>

    <span class="red">ABCD</span>

</body>

</html>
