This helps prevent poorly written scripts from eating up all available memory on a server.<\/p>\n\n\n\n<p>There are many ways by which you can set the memory limit.<\/p>\n\n\n\n<p>1. Set <i><a href=\"https:\/\/moodle.org\/mod\/forum\/discuss.php?d=378214\" target=\"_blank\" rel=\"noopener\">memory_limit <\/a>= 16M<\/i> to your server&#8217;s php.ini file (recommended, if you have root access) [applies to the whole server]<\/p>\n\n\n\n<p>2. Set <i>ini_set(&#8216;memory_limit&#8217;, &#8217;16M&#8217;);<\/i> to your site&#8217;s default settings file [in case of some CMS sites] [applies to the whole site]<\/p>\n\n\n\n<p>3. Set <i>php_value memory_limit 16M<\/i> to your .htaccess file in the site&#8217;s folder [applies to the scripts under that folder].<\/p>\n\n\n\n<p>To check the memory limit applicable in the server [or in a particular folder], create a file<b>memtest.php<\/b> in the desired location, with the below contents.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\"> &lt;?php\n $step = 1;\n while(TRUE) {\n  $chunk = str_repeat('0123456789', 128*1024*$step++);\n  print 'Memory usage: '. round(memory_get_usage()\/(1024*1024)) . 'M&lt;br \/&gt;';\n  unset($chunk);\n }\n ?&gt;\n<\/pre>\n\n\n\n<p>Now access the file in your browser. The script executes till it reaches the limit.<\/p>\n\n\n\n<div style=\"height:35px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-uagb-call-to-action uagb-block-b35efb93 wp-block-button\"><div class=\"uagb-cta__wrap\"><h3 class=\"uagb-cta__title\">Scale Seamlessly \u2013 Let Us Handle Your AWS Infrastructure!<\/h3><p class=\"uagb-cta__desc\">Maximize ROI with hassle-free AWS hosting.
