To access an associative array by integer index in PHP, the code is as follows−Example Live DemoOutputThis will produce the following output−Array key and value... key: p, value: 150 key: q, value: 100 key: r, value: 120 key: s, value: 110ExampleLet us now see another example− Live DemoOutputThis will produce the following output−Array key and value... key: p, value: 150 key: q, value: 100 key: r, value: 120 key: s, value: 110 Updated Array key and value... key: p, value: 150 key: q, value: 100 key: r, value: 20 key: s, value: 10
The cosh() function Returns the hyperbolic cosine of a number. The value Returned is a floating point number.Syntaxcosh(num)Parametersnum − Specifies a number in radiansReturnThe cosh() function Returns the hyperbolic cosine of a number. The value Returned is a floating point number.Example Live DemoOutput1.54308063481521.5430806348152ExampleLet us see another example − Live DemoOutput1Example Live DemoOutput11.591953275522267.74676148375
To check whether an array is empty, the code is as follows in PHP−Example Live Demo
The cos() function Returns the cosine of a number. A numeric value between -1 and 1 is Returned representing the cosine of the angle.Syntaxcos(num)Parametersnum − The specified value in radiansReturnThe cos() function Returns cosine of a number in float. A numeric value between -1 and 1 is Returned representing the cosine of the angle.Example Live DemoOutput0.540302305868140.54030230586814ExampleLet us see another example − Live DemoOutput1
To create a copy of an object in PHP, the code is as follows−Example Live DemoOutputThis will produce the following output−JackKevin TomRyanExampleLet us now see another example − Live DemoOutputThis will produce the following output−Demo Object( [deptname] => Finance [deptzone] => West ) Demo Object( [deptname] => Finance [deptzone] => West )
The ceil() function rounds a number to the nearest integer. The value is rounded up to the nearest greatest integer.Syntaxceil(num)Parametersnum − The number to round upReturnThe ceil() function Returns the value rounded up to the nearest (up) integer.Example Live DemoOutput11ExampleLet us see another example − Live DemoOutput2ExampleLet us see another example − Live DemoOutput9-9
The base_convert() function converts a number from one base to another, for example, octal number to decimal number. The base mentioned here should be between 2 and 36. Digits in numbers with a base greater than 10 is represented with the letters a-z i.e a is 10, , d is 13, z is 35, etc.Syntaxbase_convert(num, original_base, to_base)Parametersnum − The number to convertoriginal_base − The original base. The base mentioned here should be between 2 and 36. Digits in numbers with a base greater than 10 is represented with the letters a-z i.e a is 10, , d is 13, z ... Read More
The atanh() function returns the inverse hyperbolic tangent of the specified number.Syntaxatanh(num)Parameters num − The specified number. Required.ReturnThe atanh() function returns a float value, which is the hyperbolic tangent of a number.Example Live DemoOutputINF-INFExampleLet us see another example − Live DemoOutput1.05930617082321.4722194895832-1.4722194895832ExampleLet us see another example − Live DemoOutput0
The atan2() function returns the arc tangent of two variables.Syntaxatan2(val1, val2)Parametersval1 − The dividendval2 − The divisorReturnThe atan2() function returns the arc tangent of val2/ val1 in radians. The returned value is between -Pi and Pi.Example Live DemoOutput0.785398163397450.78539816339745ExampleLet us see another example − Live DemoOutput-2.3561944901923-2.2318394956456
To merge two arrays keeping original keys in PHP, the code is as follows−Example Live DemoOutputThis will produce the following output−array(8) { ["p"]=> string(3) "150" ["q"]=> string(3) "100" ["r"]=> string(3) "120" ["s"]=> string(3) "110" ["t"]=> string(3) "115" ["u"]=> string(3) "103" ["v"]=> string(3) "105" ["w"]=> string(3) "125" }ExampleLet us now see another example − Live DemoOutputThis will produce the following output−array(1) { ["a"]=> string(5) "Jacob" }
