<p><span style="font-weight: 400;">PHP 8 is rolled out a few weeks back and it is important to know about its new features. It has introduced various new functions, improvements, and features. PHP is known as the easiest programming language to learn. <a href="https://www.elsner.com/services/php-web-development/"><strong>Every PHP Development Company USA</strong></a> is waiting to hands on the latest version and introduces new features into their platform.</span></p>
<h2 id="1-let-us-look-at-some-new-features-of-php-8"><b>Let us Look at Some New Features of PHP 8:</b></h2>
<h3 id="2-the-php-jit-compiler"><b>The PHP JIT Compiler</b></h3>
<p><span style="font-weight: 400;">PHP interprets the code line by line instead of compiling. The JIT compiler works by compiling the parts of code during runtime and performs this similarly to the cached version of the code. The new feature is tested and it will lead to a massive improvement in terms of performance. </span></p>
<h3 id="3-json-extension"><b>JSON Extension </b></h3>
<p><span style="font-weight: 400;">The scripting language that is the JSON extension had an option to be turned off in the earlier versions. Since JSON is an important format and many PHP Development Companies decided that this extension should be active all the time. </span></p>
<h3 id="4-union-types"><b>Union Types </b></h3>
<p><span style="font-weight: 400;">With this PHP 8 version, two or more languages can form a union. There is a restriction as void cannon be a part of union type it does not return value in the output. </span></p>
<h3 id="5-order-of-string-operators"><b>Order of String Operators</b></h3>
<p><span style="font-weight: 400;">This feature was earlier <a href="https://www.elsner.com/php-7-4-released/"><strong>introduced during PHP 7.4</strong></a> but now it is kept in full effect. This feature reacts more intelligently with the multiple operators:</span></p>
<p><b>Previously:</b></p>
<ul>
<li><span style="font-weight: 400;">Echo (“sum ” .$a) + $b;</span></li>
</ul>
<p><b>Now:</b></p>
<ul>
<li><span style="font-weight: 400;">Echo “sum:” .$a + $b;</span></li>
</ul>
<h3 id="6-default-reporting-of-error"><b>Default Reporting of Error</b></h3>
<p><span style="font-weight: 400;">Many errors were ignored previously and provide output like E_ALL, E_DEPRECEATED, and E_NOTICE. This new feature allows the detection of errors just make sure you set the display_errors=Off on the server-side. You might need to </span><span style="font-weight: 400;">hire a PHP Expert to understand these reports and resolve the issues effortlessly. </span></p>
<h3 id="7-engine-warnings"><b>Engine Warnings</b></h3>
<p><span style="font-weight: 400;">Until PHP 8 was rolled over there were many errors that only displayed warnings or notes. Now it has been updated with a <a href="https://www.php.net/manual/en/function.error-reporting.php" target="_blank" rel="noopener noreferrer"><strong>full list of new PHP error messages</strong></a> that can be seen in the documentation. </span></p>
<h3 id="8-type-errors"><b>Type Errors</b></h3>
<p><span style="font-weight: 400;">Earlier User-Defined functions were used to trigger TypeErrors and internal functions issued warnings. Now with PHP 8.0, the internal functions will output the TypeErrors.</span></p>
<h3 id="9-type-annotations"><b>Type Annotations</b></h3>
<p><span style="font-weight: 400;">The internal functions and methods will have the correct type of annotations. </span></p>
<h3 id="10-conversion-of-datetime"><b>Conversion of DateTime</b></h3>
<p><span style="font-weight: 400;">The developers have made it easier to convert DateTime and DateTimeImmutable using two functions:</span></p>
<ul>
<li style="font-weight: 400;"><span style="font-weight: 400;">DateTime::createFromInterface()</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">DatetimeImmutable::createFromInterface()</span></li>
</ul>
<h3 id="11-stringable-interface"><b>Stringable Interface</b></h3>
<p><span style="font-weight: 400;">In the earlier version of PHP, this had to be performed manually but with the update, the interface is implemented automatically. </span></p>
<h3 id="12-usage-of-a-class-for-objects"><b>Usage of :: a class for Objects</b></h3>
<p><span style="font-weight: 400;">Instead of using get_class() to assign the class to objects now apply ::class to objects directly. This makes the source code short and easy to decode. </span></p>
<h3 id="13-weak-map"><b>Weak Map</b></h3>
<p><span style="font-weight: 400;">WeakRefs and WeakMaps are used to delete objects when the cache references the entity class of objects. This helps in the resource-saving handling of objects. </span></p>
<h3 id="14-static-return-type"><b>Static Return Type</b></h3>
<p><span style="font-weight: 400;">Static is a special class name that performs a valid return type in the new version. </span></p>
<h2 id="15-new-functions-introduced-for-php-web-development-services"><b>New Functions Introduced for </b><b>PHP Web Development Services </b></h2>
<h3 id="16-str_contains"><b>Str_contains</b></h3>
<p><span style="font-weight: 400;">There are different ways to find if one string contains another. Earlier you used strpos() which used haystack and needle to look for the string and returns integer indication first position where the needle is found. Since it&#8217;s the returning position of one string into another, you cannot check whether strops() found it or not. To avoid this now you have str_contains() which returns Boolean value while makes it easier to know whether or not the needle is in the haystack. It makes the procedure easy to write and maintain the code. </span></p>
<h3 id="17-str_starts_with-and-str_ends_with"><b>Str_starts_with() and str_ends_with()</b></h3>
<p><span style="font-weight: 400;">These two functions allow you to search for a needle inside the string. They check if the given string starts or ends with another string. </span></p>
<ul>
<li><span style="font-weight: 400;">Str_starts_with (string $haystack , string $needle) : bool</span></li>
<li><span style="font-weight: 400;">Str_ends_with (string $haystack , string $needle) : bool</span></li>
</ul>
<p><span style="font-weight: 400;">Both these functions will return false if the $needle is longer than the $haystack.</span></p>
<h3 id="18-get_debug_type"><b>get_debug_type</b></h3>
<p><span style="font-weight: 400;">This new function returns the type of variable. This is similar to the gettype function but it returns native type names and resolves class names. </span></p>
<h3 id="19-fdiv"><b>Fdiv()</b></h3>
<p><span style="font-weight: 400;">This function is similar to the fmod() and intdiv() functions which allow division by 0. Instead of displaying errors, it will give you INF, NAN, or -INF depending on your case. </span></p>
<h3 id="20-get_resource_id"><b>get_resource_id()</b></h3>
<p><span style="font-weight: 400;">The resources in PHP are special variables that refer to external resources. PHP 8 adds this function to make the operation obvious and type-safe:</span></p>
<ul>
<li><span style="font-weight: 400;">$resourceId = get_resource_id($resource);</span></li>
</ul>
<h3 id="21-wrapping-it"><b>Wrapping It!</b></h3>
<p><span style="font-weight: 400;">We have shared with you some of the interesting features and functions that are rolled out with PHP 8.
