With the PHP 8 release, the level of excitement in the market has increased. It was released on November 26, 2020, and can\u00a0<\/span><span lang=\"EN-IN\"><a href=\"https:\/\/www.php.net\/releases\/8.0\/en.php\" target=\"_blank\" rel=\"nofollow noopener\">download from here<\/a>.

Besides breaking the changes, PHP 8 brings a nice set of features like JIT complier, attributes, union types, etc.<\/span><\/p>\n<\/div>\n<\/div>\n<div class=\"vc_empty_space\"><\/div>\n<div class=\"wpb_text_column wpb_content_element tbs-custom-h3\">\n<div class=\"wpb_wrapper\">\n<p>Before moving with new features, let\u2019s understand the problems we faced in the old code.<\/p>\n<p>If you\u2019re planning to opt for <span data-sheets-root=\"1\" data-sheets-value=\"{&quot;1&quot;:2,&quot;2&quot;:&quot;php 8.0 features&quot;}\" data-sheets-userformat=\"{&quot;2&quot;:4288,&quot;9&quot;:0,&quot;10&quot;:0,&quot;15&quot;:&quot;Arial&quot;}\">php 8.0 features<\/span>, make sure you should expect old code is no longer compatible.

There not much noticeable difference in IO-bound web applications that provides a performance boost for CPU-heavy applications. As JIT is still new and comes with bug fixes, it\u2019s late as a day before PHP 8 released. It makes debugging and profiling more challenging by adding an extra layer to it.<\/span><\/p>\n<p><span lang=\"EN-IN\">\u00a0<\/span><\/p>\n<p><b><span lang=\"EN-IN\"># Enabling JIT in php.ini<\/span><\/b><\/p>\n<p><b><span lang=\"EN-IN\">opcache.enable=1<\/span><\/b><\/p>\n<p><b><span lang=\"EN-IN\">opcache.jit_buffer_size=100M<\/span><\/b><\/p>\n<p><b><span lang=\"EN-IN\">opcache.jit=tracing<\/span><\/b><\/p>\n<\/div>\n<\/div>\n<p>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner el_id=&#8221;fivemain&#8221;][vc_column_inner][vc_custom_heading text=&#8221;Union Types&#8221; font_container=&#8221;tag:h2|font_size:17|text_align:left&#8221; use_theme_fonts=&#8221;yes&#8221;][vc_column_text]<\/p>\n<div class=\"wpb_text_column wpb_content_element \">\n<div class=\"wpb_wrapper\">\n<p><span lang=\"EN-IN\">The union type extends type declarations using return types, class properties, and parameters to declare more than one type.
