<?php\n
<\/p>\n
try {
\/\/ Just some code…
} catch (Exception1 $e) {
\/\/ Some code to handle the exception
} catch (Exception2 $e) {
\/\/ Same code to handle this different exception
} catch (Exception3 $e) {
\/\/ Some other code…
}<\/p>\n<\/div>\n\n\n\n
It is obvious from the example that in this case devs will need to copy and paste code and also the code doesn\u2019t look clean and beautiful. With PHP 7.1 you can do the following to catch multiple exceptions and handle them:<\/span><\/p>\n\n\n\n<?php<\/span>
<\/span>
<\/span>try {<\/span>
<\/span> \/\/ Just some code…<\/span>
<\/span>} catch (Exception1 | Exception2 $e) {<\/span>
<\/span> \/\/ Code to handle the exception<\/span>
<\/span>} catch (Exception3 $e) {<\/span>
<\/span> \/\/ Some other code…<\/span>
<\/span>}<\/span><\/div>\n\n\n\nThis looks much better and allows us to catch multiple exceptions.<\/span>
<\/span>2. Nullable Types<\/b>. PHP 7.0 introduced the type-declaration mechanism and we loved it. However, we had the feeling that it would be great to declare a parameter, indicate it could be \u201cnull\u201d and at the same time make this optional. This is now possible in PHP 7.1. The following code was not working in PHP 7.0:<\/span><\/p>\n\n\n\nfunction func01(int $g) {
var_dump($g);
}\n
<\/p>\n
func01(100); \/\/ int(100)
func01(null); \/\/ TypeError<\/p>\n<\/div>\n\n\n\n
The second time we call the function PHP 7.0 will return an error message because \u201cnull\u201d is not supported and the function expects an integer. In order to fix this code we had to use if statements to check if the function is passed \u201cnull\u201d. PHP 7.1 resolves this issue very elegantly and in order to achieve our goal we just need to modify the function and add a single question mark in the beginning of a type\u2019s name:<\/span><\/p>\n\n\n\nfunction func01(?int $g) {
var_dump($g);
}<\/div>\n\n\n\n
This means that null is optional. Nice!<\/span><\/p>\n\n\n\n3. The mcrypt library has been deprecated<\/b>. Everyone knows that if you\u2019re typing mcrypt and adding it to your code then you are doing it wrong and you have to check and replace your code in favor of OpenSSL. Still, we love the fact that mcrypt has finally been deprecated and soon will completely be removed. This way PHP now forces new developers to use OpenSSL instead of mcrypt.<\/span><\/p>\n\n\n\n
