Is it possible to concatenate strings, as follows? And if not, what is the alternative of doing so?
while ($personCount < 10) {
$result += $personCount . "person ";
}
echo $result;
It should appear like 1 person 2 person 3 person, etc.
You can’t use the + sign in concatenation, so what is the alternative?
Just use . for concatenating.
And you missed out the $personCount increment!
while ($personCount < 10) {
$result .= $personCount . ' people';
$personCount++;
}
echo $result;
One step (IMHO) better
$result .= $personCount . ' people';
This should be faster.
while ($personCount < 10) {
$result .= "{$personCount} people ";
$personCount++;
}
echo $result;
"{$personCount} people" is faster than $personCount . ' people'? Otherwise it just seems like wild speculation...
. instead .= (the first instance) does affect performance (probably due to the Schlemiel the Painter's algorithm - this can happen in any language or system), but it is already using .=.$text .= "additional text"; instead of $text = $text . "additional text"; can seriously enhance performance due to memory allocation efficiency. I reduced execution time from 5 seconds to 0.5 seconds (10 times) by simply switching to the first pattern for a loop with 900 iterations over a string $text that reaches 800K by the end."while ($personCount < 10) {
$result .= ($personCount++)." people ";
}
echo $result;
I think this code should work fine:
while ($personCount < 10) {
$result = $personCount . "people ';
$personCount++;
}
# I do not understand why you need the (+) with the result.
echo $result;
"people ' instead of 'people '.
$personCount = 1;
while ($personCount < 10) {
$result = 0;
$result .= $personCount . "person ";
$personCount++;
echo $result;
}
