To get the first day of the week in PHP, the code is as follows −Example Live DemoOutputThis will produce the following output −First day = Monday - 09/12/2019ExampleLet us now see another example − Live DemoOutputThis will produce the following output −Displaying Sunday as first day of a week... First day (next week) = Sunday - 15/12/2019

To get the first element of an array in PHP, the code is as follows −Example Live DemoOutputThis will produce the following output−Array value ... Value 1 = 150ExampleLet us now see another example − Live DemoOutputThis will produce the following output −Value 1 = 150

To get random value out of an array in PHP, the code is as follows−Example Live DemoOutputThis will produce the following output −Array values ... Value 1 = 150 Value 2 = 100 Value 3 = 120 Value 4 = 110 Value 5 = 115 Value 6 = 103 Value 7 = 105 Value 8 = 125 Random value from arary = 110ExampleLet us now see another example − Live DemoOutputThis will produce the following output−Array values ... Value 1 = 150 Value 2 = 100 Value 3 = 120 Value 4 = 110 Value 5 = 115 Value 6 = 103 Value 7 = 105 Value 8 = 125 Random values from array...150 115

To concatenate two strings in PHP, the code is as follows −Example Live DemoOutputThis will produce the following output−1.967 and 1.969 Both the values are equal!ExampleLet us now see another example − Live DemoOutputThis will produce the following output−First Name = Jack Second Name = Sparrow Concatenation = JackSparrow

To compare float values in PHP, the code is as follows −Example Live DemoOutputThis will produce the following output−2.5 3.5 Both the values aren\'t equalExampleLet us now see another example − Live DemoOutputThis will produce the following example−1.967 1.969 Both the values are equal!

The difference is the precedence when we compare AND with && operator. The precedence of AND operator is lower than the operator = when the evaluation is performed, therefore even if both the operators do the same work, the result is different.ExampleLet us first see an example of the AND operator− Live DemoOutputThis will produce the following output−Result = TrueExampleLet us now see an example of the && operator− Live DemoOutputThis will produce the following output:Result = TrueExampleLet us now see the difference in a single example − Live DemoOutputThis will produce the following output−true false

To compare two dates in PHP, the code is as follows. Here, we have used the equality operator to compare dates −Example Live DemoOutputThis will produce the following output−Date1 = 2019-10-30 Date2 = 2019-10-30 Both the dates are equal!ExampleLet us now see another example− Live DemoOutputThis will produce the following output−Date1 = 2019-11-08 Date2 = 2018-08-10 DateOne is the latest date!

Let's discuss the differences between errors and exceptions.Recovering from Error is not possible. The only solution to errors is to terminate the execution. Whereas we can recover from Exception by using either try-catch blocks or throwing an exception back to the caller.You will not be able to handle the Errors using try-catch blocks. Even if you handle them using try-catch blocks, your application will not recover if they happen. On the other hand, Exceptions can be handled using try-catch blocks and can make program flow normally if they happen.Exceptions are related to the application whereas Errors are related to the ...
