PHP 7 is the first significant version update to PHP programming language in last few years. This means that there are several upgrades and general changes that you\u2019ll want to know about.<\/p>\n<p>PHP 7 is much faster and offers a lot of benefits over previous versions such as a new version of Zend Engine and its faster performance. PHP 7 has also removed several disapproved functions from previous versions. Because of this, you should consider upgradingyour PHP websites or web applications once everything is fully compatible with the new version of PHP.<\/p>\n<p>Dynamic websites that are built using popular content management systems (CMS) like\u00a0<strong>WordPress<\/strong>\u00a0run more efficiently and are less likely to crash when compared to older versions of PHP.<\/p>\n<\/div>\n<\/div>\n<p>[\/vc_column_text][vc_row_inner el_class=&#8221;border m-0&#8243;][vc_column_inner][vc_empty_space height=&#8221;10px&#8221;][vc_column_text css=&#8221;.vc_custom_1629888478448{border-top-width: 2px !important;border-right-width: 2px !important;border-bottom-width: 2px !important;border-left-width: 2px !important;padding-top: 15px !important;padding-right: 15px !important;padding-bottom: 15px !important;padding-left: 15px !important;border-left-color: #000000 !important;border-left-style: solid !important;border-right-color: #000000 !important;border-right-style: solid !important;border-top-color: #000000 !important;border-top-style: solid !important;border-bottom-color: #000000 !important;border-bottom-style: solid !important;border-radius: 5px !important;}&#8221; el_class=&#8221;TableOfContentMain&#8221;]<\/p>\n<h5 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Table_Of_Contents\"><\/span><strong>Table Of Contents<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h5>\n<ol>\n<li><a href=\"#onemain\"><strong>PHP 7 New Features:<br \/>\n<\/strong><\/a><\/p>\n<ul>\n<li><a href=\"#onedashone\">Scalar type declarations:<\/a><\/li>\n<li><a href=\"#onedashtwo\">Anonymous Classes:<\/a><\/li>\n<li><a href=\"#onedashthree\">Return type declarations:<\/a><\/li>\n<li><a href=\"#onedashfour\">Constant arrays using define():<\/a><\/li>\n<li><a href=\"#onedashfive\"> Null coalescing operator:<\/a><\/li>\n<li><a href=\"#onedashsix\">Spaceship operator:<br \/>\n<\/a><\/li>\n<li><a href=\"#onedashseven\">Filtered unserialize() &amp; IntlChar<br \/>\n<\/a><\/li>\n<li><a href=\"#onedasheight\">Exceptions<\/a><\/li>\n<li><a href=\"#onedashnine\">Group use declarations<\/a><\/li>\n<\/ul>\n<\/li>\n<li><a href=\"#twomain\"><strong>Key Benefits of Migrating to PHP 7:<\/strong><\/a><\/li>\n<li><a href=\"#threemain\"><strong>PHP 7 also offers One-Click installs for following platforms:<\/strong><\/a><\/li>\n<\/ol>\n<p>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_empty_space height=&#8221;10px&#8221;][vc_cta h2=&#8221;&#8221; txt_align=&#8221;center&#8221; color=&#8221;grey&#8221; add_button=&#8221;right&#8221; btn_title=&#8221;Lets Discuss your App Idea&#8221; btn_color=&#8221;turquoise&#8221; btn_align=&#8221;center&#8221; btn_i_icon_fontawesome=&#8221;fas fa-arrow-circle-right&#8221; add_icon=&#8221;left&#8221; i_type=&#8221;monosocial&#8221; i_icon_monosocial=&#8221;vc-mono vc-mono-blogger&#8221; i_color=&#8221;custom&#8221; i_size=&#8221;lg&#8221; btn_add_icon=&#8221;true&#8221; btn_link=&#8221;url:https%3A%2F%2Fwww.techcronus.com%2Fcontact-us|title:Lets%20Discuss%20your%20App%20idea&#8221; btn_el_class=&#8221;TBS-ca-btn font-weight-bold&#8221; i_el_class=&#8221;TBS-ca-icon&#8221; el_class=&#8221;CustomBlogDtlCTA&#8221; i_custom_color=&#8221;#5ac6c6&#8243;]<\/p>\n<h6 class=\"mt-0 mb-0 capitalize\"><span class=\"ez-toc-section\" id=\"Have_An_Awesome_Idea_For_Your_Mobile_App_Development\"><\/span><strong>Have An Awesome Idea For Your Mobile App Development?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h6>\n<p>[\/vc_cta][vc_row_inner el_id=&#8221;onemain&#8221;][vc_column_inner][vc_empty_space height=&#8221;10px&#8221;][vc_custom_heading text=&#8221;PHP 7 New Features:<br \/>\n&#8221; font_container=&#8221;tag:h2|font_size:20px|text_align:left&#8221; use_theme_fonts=&#8221;yes&#8221;][\/vc_column_inner][\/vc_row_inner][vc_row_inner el_id=&#8221;onedashone&#8221;][vc_column_inner][vc_custom_heading text=&#8221;Scalar type declarations:&#8221; font_container=&#8221;tag:h2|font_size:20|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 class=\"normal\">Scalar\u00a0<strong>type declarations<\/strong>\u00a0come in two flavors: coercive (default) and strict.
