No, it says that an array with 1,000,000 integers uses well over 100 MB. nikic has explained what's happening behind the scenes quite nicely in a blog article: <https://nikic.github.io/2011/12/12/How-big-are-PHP-arrays-really-Hint-BIG.html> Previous Comments: ------------------------------------------------------------------------ [2015-03-26 07:55:40] nils-kuebler at web dot de Description: ------------ This text is telling me that an Integer in PHP is 100 Bytes big? "A simple example of this is to reimplement the range() function as a generator. The standard range() function has to generate an array with every value in it and return it, which can result in large arrays: for example, calling range(0, 1000000) will result in well over 100 MB of memory being used.
