I am trying to simply replace some new lines and have tried three different ways, but I don't get any change:
$description = preg_replace('/\r?\n|\r/', '<br/>', $description);
$description = str_replace(array("\r\n", "\r", "\n"), "<br/>", $description);
$description = nl2br($description);
These should all work, but I still get the newlines. They are double: "\r\r". That shouldn't make any of these fail, right?
There is already the nl2br()
function that inserts <br>
tags before new line characters:
Example (codepad):
<?php
// Won't work
$desc = 'Line one\nline two';
// Should work
$desc2 = "Line one\nline two";
echo nl2br($desc);
echo '<br/>';
echo nl2br($desc2);
?>
But if it is still not working make sure the text $desciption
is double-quoted.
That's because single quotes do not 'expand' escape sequences such as \n
comparing to double quoted strings. Quote from PHP documentation:
Note: Unlike the double-quoted and heredoc syntaxes, variables and escape sequences for special characters will not be expanded when they occur in single quoted strings.
