Finding and removing numbers (1-25) from a string ...

[AshleyQuick]

%3$s displays a string of text that always begins with a number followed by a colon (from 1-25 only).

 

1:

2:

3:

etc...

 

Is there a way to remove the number and the colon entirely and leave the rest of the string intact?

 

function wp_rss( $url, $num_items = -1 ) {
if ( $rss = fetch_rss( $url ) ) {

	if ( $num_items !== -1 ) {
		$rss->items = array_slice( $rss->items, 0, $num_items );
	}
	//start count
	$i = 1;
	foreach ( (array) $rss->items as $item ) {
		printf(
			'<div title="%2$s"><strong>'.$i.'</strong></div><div>%3$s</div>',
			esc_url( $item['link'] ),
			esc_attr( strip_tags( $item['description'] ) ),
			htmlentities( $item['title'] )
		);
	//increment
	$i++;
	}

<?php

$string = '15:Some text.';
$newString = preg_replace('/([0-9]*?)\:/', '', $string, 1);

echo $newString;

?>

$string = '15:Some text.';
$string = array_pop(explode(':', $string, 1));

echo $string;

$string = '15:Some text.';
$string = array_pop(explode(':', $string, 1));

echo $string;

Would be ..

 

<?php

$string = '15:Some text.';
$string = array_pop(explode(':', $string, 2));

echo $string;

?>

I used preg_replace() to confirm it was a number being removed though.  I'm not sure they would want a string such as "Some Text: And More Text" to remove everything up until the first colon.  If every string has the number before it though, then either way would be fine.
