[SOLVED] quick question

[gevo12321]

you know how in if statements you have to use == because you r comparing

do you also use !== or do u use just != in if statements

[The Little Guy]

depends.

 

1 === "1"    evaluates false

1 !== "1"      evaluates true

[gevans]

you can use != this will just compare the two variables

 

!== will do an exact comparison, comparing the variable and variable type

so that means if it compares a string to a interger, such as this:

 

if(1 !== "1")
echo 'here 2';

 

it will echo out "here 2" because an integer does not equal a string even thought they are both 1.

 

if you don't have the triple comparison:

 

if(1 != "1")
echo 'here 2';

 

that will not echo out "here 2" because 1 does equal 1.
