Default 10.ReturnThe IntlChar::forDigit() function returns the character representation of specified digit in the specified radix.ExampleThe following is an example −OutputThe following is the output −int(55) int(53) int(48)
The IntlChar::chr() function is used to check whether the entered character is Unicode value or notSyntaxIntlChar::chr( val )Parametersval − A character value encoded as a UTF-8 string.ReturnThe IntlChar::chr() function returns TRUE if the val is a Unicode character.ExampleThe following is an example −OutputThe following is the output −string(1) "A" NULL string(1) "^"
The param() method in jQuery is used to create a serialized representation of an array or object.SyntaxThe syntax is as follows −$.param(obj, val)Above, obj is the object to serialize, whereas Val specifies whether or not to use the traditional style of param serialization.ExampleLet us now see an example to implement the jQuery param() method− Live Demo $(document).ready(function(){ ob = new Object(); ob.stdid = "S01"; ob.roll = 3; $("button").click(function(){ $("p").text($.param(ob)); }); }); Student Details Serialized Representation OutputThis will produce the following output−Click on the button to get serialized representation−
The IntlChar::ord()function is used to return the Unicode code point value of the entered character.Syntaxint IntlChar::ord( char_unicode )Parameterschar_unicode − A Unicode CharacterReturnThe IntlChar::ord()function returns theUnicode value as an integer.ExampleThe following is an example −OutputThe following is the output −int(72) int(57)ExampleLet us see another example −OutputThe following is the output −int(37) NULL
