PHP Text Spinner

Posted by admin on Monday, February 1, 2010 · 5 Comments  Protected by Copyscape Unique Content Check

You know what text/article spinners are and what they are used for. Usually article spinning is used to spin articles and submit “unique” spun copies to different article directories and other websites. But what if you wanted to spin the text automatically on your website?
Recently I needed such functionality on one of my websites and as a result I’ve created a PHP function that would spin text provided in a spinner syntax. The function turned out to be so simple that I’ve decided to post it here should anyone need it.
As it turns out there are even commercial PHP spinners out there that cost a nice buck – you get to use this one for free! The function is a simple spinner that just spits out a spun text and supports nested syntax:
function spin($s){
	preg_match('#\{(.+?)\}#is',$s,$m);
	if(empty($m)) return $s;

	$t = $m[1];

	if(strpos($t,'{')!==false){
		$t = substr($t, strrpos($t,'{') + 1);
	}

	$parts = explode("|", $t);
	$s = preg_replace("+\{".preg_quote($t)."\}+is", $parts[array_rand($parts)], $s, 1);

	return spin($s);
}

//Example:
echo spin('{This|Here} is {some|a {little|wee} bit of} {example|sample} text.');
Enjoy!
Edit (March 19, 2010): Found a bug with nesting levels 3 and up – the code is updated (using strrpos instead of strpos).

You only have to do these 3 things to make money. Do you know them?

    I’m going to try it and see. Thanks so much for sharing it with your readers.

    Wow, that is very clean.
    Shortest spin code I have ever seen by far.

    Thanks!

    function spin($s){
    preg_match(‘#\{(.+?)\}#is’,$s,$m);
    if(empty($m)) return $s;
    $t = $m[1];
    if(strpos($t,’{‘)!==false){
    $t = substr($t, strrpos($t,’{‘) + 1);
    }
    $parts = explode(“|”, $t);
    $s = preg_replace(“+\{“.preg_quote($t).”\}+is”, $parts[array_rand($parts)], $s, 1);
    return spin($s);
    }

    $spin2 = spin(‘{#1|#2|#3|#4|#5|#6|#7|#8|#9|#10|#11|#12|#13|#14|#15|#16|#17|#18|#19|#20}’);

    $speak = spin(‘{interesting|awesome|amazing|cool|informative|wierd|dope|wicked|neat|swell|inspiring|audacious|fullfilling|kickass|super cool} {site|page|article|link|file|place|zone|method|failure|success story|tactic}’);

    What I need to do is call the results of the $spin2 function (ie: #1, #2 etc) and the results of $speak (ie: interesting failure etc…) into a new function using the same spin code:

    $awesome = $spin(‘{$spin2|$speak}’);

    so that $awesome will return either “#1″ OR “awesome method” etc…

    Right now, using the code above, I get a result returned of the actual function

    ie: the echo is “$spin2″ or “$speak” instead of the results OF the function.

    Hopefully this makes sense, and hopefully someone can give me some useful code here.

    Thanks ahead of time!!

    Hi Shane,

    If I understand you correctly, you just have to drop spin() function from $spin2 and $speak:

    $spin2 = ‘{#1|#2|#3|#4|#5|#6|#7|#8|#9|#10|#11|#12|#13|#14|#15|#16|#17|#18|#19|#20}’;

    $speak = ‘{interesting|awesome|amazing|cool|informative|wierd|dope|wicked|neat|swell|inspiring|audacious|fullfilling|kickass|super cool} {site|page|article|link|file|place|zone|method|failure|success story|tactic}’;

    $awesome = spin(“{$spin2|$speak}”);

    Note the double quotes in the above line.
