Trim leading white space with PHP?

php, trim, whitespace

Solution

Strip all whitespace from the left end of the title:

<?php echo ltrim(wp_title('')); ?>

Strip all whitespace from either end:

<?php echo trim(wp_title('')); ?>

Strip all spaces from the left end of the title:

<?php echo ltrim(wp_title(''), ' '); ?>

Remove the first space, even if it's not the first character:

<?php echo str_replace(' ', '', wp_title(''), 1); ?>

Strip only a single space (not newline, not tab) at the beginning:

<?php echo preg_replace('/^ /', '', wp_title('')); ?>

Strip the first character, whatever it is:

<?php echo substr(wp_title(''), 1); ?>

Update

From the Wordpress documentation on `wp_title`, it appears that `wp_title` displays the title itself unless you pass `false` for the second parameter, in which case it returns it. So try:

<?php echo trim(wp_title('', false)); ?>

Problem

There seems to be a bug in a Wordpress PHP function that leaves whitespace in front of the title of the page generated by `<?php echo wp_title(''); ?>` I've been through the Wordpress docs and forums on that function without any luck. I'm using it this way `<body id="<?php echo wp_title(''); ?>">` in order to generate an HTML body tag with the id of the page title. So what I need to do is strip that white space, so that the body tag looks like this `<body id="mypage">` instead of this `<body id=" mypage">` The extra white space kills the CSS I'm trying to use to highlight menu items of the active page. When I manually add a correct body tag without the white space, my CSS works. So how would I strip the white space? Thanks, Mark Part Two of the Epic John, A hex dump was a good idea; it shows the white space as two "20" spaces. But all solutions that strip leading spaces and white space didn't. And, `<?php ob_start(); $title = wp_title(''); ob_end_clean(); echo $title; ?>` gives me `< body id ="">` and `<?php ob_start(); $title = wp_title(''); echo $title; ?>` gives me `< body id =" mypage">` Puzzle. The root of the problem is that wp_title has optional page title leading characters - that look like chevrons - that are supposed to be dropped when the option is false, and they are, but white space gets dumped in. Is there a nuclear option? Yup, tried them both before; they still return two leading spaces... arrgg
