How to use if within for

There s many question i got about this part but its all regarding the fact about how to use the if within a for... a tried a couple of things but since there s no clear examples of any if being issued within a for or any isset it was hard to get my head around it, i was thinking this answer had something with the third expression after it realized the value was equal, but well i was wrong, any information will be very much appreciated

index.php
<?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($loop=0;$loop++ <100;){
echo "$loop";
} if (isset($facts[$loop])){
  echo $facts[$loop];
}

You just have an issue with brackets. Move the closing bracket before the if statement to the end of the code so the if statement is included in the 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

for($loop=0;$loop++ <100;){
echo "$loop";
if (isset($facts[$loop])){
  echo $facts[$loop];
}
}
