My base64 encoded string is extremely long and lacks spaces or line breaks, causing it to be displayed on a single line with an unsightly horizontal scroll bar in a textarea.
Is there a way for me to manually insert carriage returns after using base64_encode() but before displaying the text in the textarea? And then remove these carriage returns before decoding the string retrieved from the textarea?
If you want to break your string into chunks of a specific length and then put them back together with the desired character or string, consider using chunk_split:
$str = base64_encode($data);
echo '<textarea name="text">'
. chunk_split($str, 50, "\n") // add a newline every 50 characters
. '</textarea>';
Since base64_decode disregards spaces, simply retrieve the textarea value without any special processing needed.
Absolutely. When it comes to programming, white space is often disregarded:
<?php
echo base64_encode('Hello World'); // SGVsbG8gV29ybGQ=
echo base64_decode('SGVs bG8g V29y bGQ='); // Hello World
?>
Using base64_decode with wordwrap and base64_encode can be a useful way to manipulate long strings of text while maintaining their integrity.
Instead of relying on PHP, you have the option to utilize the HTML attribute wrap directly in your code...
<textarea name="bar" wrap="soft"><?php echo $encodedText; ?></textarea>
Utilizing the PHP function wordwrap can achieve this.
