These methods above let you replace one semicolon only. Here is the code to remove all semicolons:

function rw_remove_semicolons($match) {
	$s = $match[0];
	return str_replace(';', '', $s);
}

// test

$s = "In 1986 IBM recorded the largest profit ever recorded by any corporation in the the history of the world. Nothing would ever be able to compete with IBM. The media was in a swoon about how amazing IBM was. But IBM was already losing ground in the PC market, and they were losing ground in electronics to the Japanese.

// usage

$s = preg_replace_callback('#\[\[.*?\]\]#', 'rw_remove_semicolons', $s);
