4,309 PointsI have a problem with isset function, for loops and switch-case
Task: "Use the function isset to test if the incremented value equals one of the keys in the $facts array. If there is a key that matches, display the value AFTER the number."
(NOTE: all numbers between 1 and 100 should still be displayed)
After what I did: "Bummer! Make sure the fact is displayed directly after the number."
What did I do wrong?
<?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 <= 100; $i++) {
echo $i . "\n";
switch($i) {
case isset($facts[57]):
echo $facts[57] . "\n";
break;
case isset($facts[2]):
echo $facts[2] . "\n";
break;
case isset($facts[18]):
echo $facts[18] . "\n";
break;
case isset($facts[10]):
echo $facts[10] . "\n";
break;
case isset($facts[11]):
echo $facts[11] . "\n";
break;
case isset($facts[98]):
echo $facts[98] . "\n";
break;
case isset($facts[69]):
echo $facts[69] . "\n";
break;
default:
echo "Something is wrong!";
}
}

You can use an if statement here and then check if it isset.
If that`s the case then you can echo out the facts
<?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 <= 100; $i++) {
echo $i . "\n";
/*
Use if statment instead of switch
Check if $facts[$i] and the number are set
*/
if(isset($facts[$i])){
// then echo out the $facts[$i]
echo "$facts[$i];
}
// add a linebreak here so everything is on it`s own line
echo "<br />";
}
