2,887 PointsLost in for Loop challenge
Struggling with loops from the start and this has thrown me even more. Don't know whether to use count function or do i need to sort the array first. I am close to cancelling my subs now as i find the PHP instructor lazy just copying and pasting old code into loops which is just confusing. Plus these code challenges are forever poorly explained.
<?php
$facts = array(
57 => ' on Heinz ketchup bottles represents the number of varieties of pickles the company once had.',
2 => ' is the approximate hours a day Giraffes sleeps',
18 => ' is the average hours a Python sleeps per day',
10 => ' per cent of the world is left-handed.',
11 => ' Empire State Buildings, stacked one on top of the other, would be required to measure the Gulf of Mexico at its deepest point.',
98 => '% of the atoms in your body are replaced every year',
69 => ' is the largest number of recorded children born to one woman',
);
//add your loop below this line
for ($facts = 1; $facts < 101; $facts++) {
echo "$facts";
}

Full Stack JavaScript Techdegree Student 22,368 PointsHere is your answer. I would recommend to make a filter, so only the $i = key value is showing. The output you have now is with a lot of white spaces. I can't log into to the challenge to replicate your issue, so hope you can use my answer. Remember that $facts is an array and to get the value out you need to do $facts[$i].
Your fix would work here but not the best way in my oppinion. I would use FOREACH loop. Look further down
<?php
$facts = array(
57 => ' on Heinz ketchup bottles represents the number of varieties of pickles the company once had.',
2 => ' is the approximate hours a day Giraffes sleeps',
18 => ' is the average hours a Python sleeps per day',
10 => ' per cent of the world is left-handed.',
11 => ' Empire State Buildings, stacked one on top of the other, would be required to measure the Gulf of Mexico at its deepest point.',
98 => '% of the atoms in your body are replaced every year',
69 => ' is the largest number of recorded children born to one woman',
);
//add your loop below this line
for ($i = 1; $i < 101; $i++) {
echo $facts[$i] . '<br>';
}
FOREACH loop
<?php
$facts = array(
57 => ' on Heinz ketchup bottles represents the number of varieties of pickles the company once had.',
2 => ' is the approximate hours a day Giraffes sleeps',
18 => ' is the average hours a Python sleeps per day',
10 => ' per cent of the world is left-handed.',
11 => ' Empire State Buildings, stacked one on top of the other, would be required to measure the Gulf of Mexico at its deepest point.',
98 => '% of the atoms in your body are replaced every year',
69 => ' is the largest number of recorded children born to one woman',
);
//add your loop below this line
foreach($facts as $key => $item) {
echo $facts[$key] . '<br>';
};

for ($i = 1; $i < 101; $i++) {
echo $i;
}

2,887 PointsThanks i was almost correct but the question is rather vague to me about creating a new variable
Cliff Jackson
2,887 PointsThanks for the answer but the question did specify a FOR loop to be used on the task, but the foreach does work on this too.
