FRInteractives: "SELECT * FROM table WHERE id = $_POST[ 'id' ]" ? ******************************************************************* Q: What is the preferred way to write this if statement, and why? if( 5 == $someVar ) or if( $someVar == 5 ) *********************************************************************** Q: Given this code: function doSomething( &$arg ) { $return = $arg; $arg += 1; return $return; } $a = 3; $b = doSomething( $a ); ...what is the value of $a and $b after the function call and why? $b = 3 because it has the value of the of the inputed variable initial value. The $a was autoincremented after the return variable was assigned $a = 4 as it has been autoincremented by 1. However only valid within the function ellse undefined if called outsie it. NB. considering that &$arg is a typo *********************************************************************** Question 4 Q: Consider these lines of codes: //first code $myVar = "I am Something"; $myVar .= "So Special"; echo "Do you Know $myVar"; And //second code $myVar = "I am Something"; $myVar .= "So Special"; echo 'Do you Know $myVar'; Now if you run these two codes in a Browser what will be the output? The same Do you Know $myVar and not Do you Know I am SomethingSo Special NB. There was no concatenation between string and assumed variable |

$age= 15; ($age<15) ? 'Accept': 'Reject'; Who can explain what this code will do and what's the name of this expression? Cc jregz craigston |

cbrass: [s] Name: Ternary Operator it is a short-hand notation for writing conditional statements[/s] oOps, he asked for name of expression not operator's name. Expression name: Conditional Expression ($age<15) ? 'Accept': 'Reject'; the above code will return Accept if age is less than 15 Else it returns Reject 3 Likes |

codemarshal08: Correct man |
Re: Webmasters Enter Here If You Can Solve These PHP Questions... by Nobody: 4:02pm On Apr 30, 2015 |
FRInteractives: the correct way to write this statement is: if ($SomeVar == 5) cos somevar in a variable and if the value stored in the memory block is equal to 5, then condition for the statement would be meant. |
