To check substring in a string, the code is as follows in PHP −Example Live DemoOutputThis will produce the following output−String = How I Met Your Mother Substring = Mother Substring found successfullyExampleLet us now see another example − Live DemoOutputThis will produce the following output−String = In the Heart of Sea Substring = Ocean Substring not found

To add days to $Date in PHP, the code is as follows−Example Live DemoOutputThis will produce the following output−Displaying date... Date = 2019-11-11 Displaying updated date... 2019-12-01ExampleLet us now see another example − Live DemoOutputThis will produce the following output−Displaying Date...2019/11/11 Displaying Updated Date... 2019/12/06

To convert string to boolean in PHP, the code is as follows. Use the filter_val() method−Example Live DemoOutputThis will produce the following output−Displaying Sunday as first day of a week... First day (next week) = Sunday - 15/12/2019 bool(false)ExampleLet us now see another example − Live DemoOutputThis will produce the following output−bool(false) bool(true) bool(false) bool(false)

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!
