I am trying to get the following code to add how many people can retire and not. the code displays but does not add. What am I doing wrong?
<?php
$canRetire= 0;
$notRetired = 0;
$agesFile = fopen("ages.txt", "r");
$nextAge = fgets($agesFile);
while (feof($agesFile) ){
list($agesFile)=explode(":",$nextAge);
if ($agesFile > 65){
$canRetired = $canRetired + 1;
}
else{
$notretired = $notRetired + 1;
}
$nextAge = fgets($agesFile);
}
fclose ($agesFile);
print("<p>Number of people can retired : $canRetired</p>");
print("<p>Number of people not retired: $notRetired</p>");
?>

Answer 1

Shouldn't it be while(!feof(...))?
You want to stop when you reach the end of file.
Plus it looks like you've got some spelling errors:
$notretired = $notRetired + 1;
Notice how the R is lower case on the left and upper case on the right.
Also at the beginning you have $canRetire and in the if condition inside the loop you have $canRetired.
And just another little hint for you: $notRetired = $notRetired + 1; is the same as $notRetired++;

Answer 2

Made a couple modifications to cases, and what appears to be a type based on the variables you have defined. Looks like the variable $canRetire does not match $canretired.
Using while(feof($fh)) is basically saying, do this for the EOF. Which renders that entire loop useless. Using while(!feof($fh)) will allow you to loop until the EOF.
<?php
$canRetired= 0;
$notRetired = 0;
$agesFile = fopen("ages.txt", "r");
$nextAge = fgets($agesFile);
while (!feof($agesFile) ){
list($agesFile)=explode(":",$nextAge);
if ($agesFile > 65){
$canRetired = $canRetired++;
}
else{
$notRetired = $notRetired++;
}
$nextAge = fgets($agesFile);
}
fclose ($agesFile);
print("<p>Number of people can retired : $canRetired</p>");
print("<p>Number of people not retired: $notRetired</p>");
?>
