Conditional statement are statements that can only be carried out on the basis of compliance with a specific condition(s). A conditional statement allows a programmer to essentially determine which path to follow depending on the assessment of the situation. Conditional claims are assessed as true or false. We use conditional statements in those cases.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where we can use Conditional statement in PHP?<\/h2>\n\n\n\n<p>In this You want to do different things under different circumstances very much as you write code. To do this, you can use conditions in your code. You will get many conditions when you code a program. So, if you face any type of Conditional statement which I have explained in this article you can easily understand the condition and apply the needed things.<\/p>\n\n\n<div class=\"epyt-gallery\" data-currpage=\"1\" id=\"epyt_gallery_66380\"><iframe loading=\"lazy\"  id=\"_ytid_89867\"  width=\"760\" height=\"427\"  data-origwidth=\"760\" data-origheight=\"427\" src=\"https:\/\/www.youtube.com\/embed\/?enablejsapi=1&#038;autoplay=0&#038;cc_load_policy=0&#038;cc_lang_pref=&#038;iv_load_policy=1&#038;loop=0&#038;rel=1&#038;fs=1&#038;playsinline=0&#038;autohide=2&#038;theme=dark&#038;color=red&#038;controls=1&#038;disablekb=0&#038;\" class=\"__youtube_prefs__  no-lazyload\" title=\"YouTube player\"  data-epytgalleryid=\"epyt_gallery_66380\"  allow=\"fullscreen; accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen data-no-lazy=\"1\" data-skipgform_ajax_framebjll=\"\"><\/iframe><div class=\"epyt-gallery-list\"><div>Sorry, there was a YouTube error.<\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>What is Conditional statement in PHP?
