How do I "increment a counter" in PHP?

Question

A person on Y!Answers said I needed to do this, but I don't know what he's talking about or how to do it... can someone give me examples?

Answer 1

A counter is just a variable you create to "keep a count" of something. For example, how many times you run a loop.

If your counter variable is "counter", you can increment it by one by doing the following:

counter = counter + 1;
or:
counter += 1;
or:
counter++;

All do the same thing.

An example using a counter "i":

for ($i = 1; $i <= 10; $i++) {
print "$i
";
}

Answer 2

this how you increment using for and while loops

for($i=0; $i<10; $i++){
echo $i;
}

//while loop
$i=0;
while($i<20){
$i++;
}
