将txt文件转换为字符串，然后转换为数组，然后打印数组的每个单词

I am trying to convert a text file into a string, then into an array and then finaly print each of the values (words) into separate 'a' holders.

The .txt file contains one line of text.

I have tried it through a for loop, like so:

    $lines = file_get_contents('test.txt', FILE_USE_INCLUDE_PATH);
    $words = explode(" ", $lines);

    for ($x = 1; $x >= 100; $x++){
        print '<a id="word$x">'$words[$x]'</a>';
    }

But that doesnt work. I am sure that I am just missing something basic, but I have tried and failed so many times, that I need others opinions and advice.

At first, don't forget about string concatenation: print '<a id="word'.$x.'">'.$words[$x].'</a>';

If you need more, than only 100 words use $x < count($words) in your for

You have to use <= instead of >=

for ($x = 1; $x <= 100; $x++){
    print '<a id="word$x">'$words[$x]'</a>';
}

You can use sprinf, it's much easier to read.

$lines = file_get_contents('test.txt', FILE_USE_INCLUDE_PATH);
$words = explode(" ", $lines);

for ($x = 1; $x >= 100; $x++){
  echo sprintf('<a id="word%s">%s</a>', $word, $words[$x]);
}

But if you don't want to, you can simply concatenate the values.

echo '<a id="word' . $x . '">' . $words[$x] . '</a>';

It is a bad practice to use explicit for loops.

$lines = file_get_contents('test.txt', FILE_USE_INCLUDE_PATH);
$words = explode(" ", $lines);
$words = array_slice($words, 0, 100);

foreach ($words as $index => $word) {
    print "<a id=\"word$x\">$word</a>";
}

Also, be aware array indexing starts with 0 not 1. If you do $x = 1 you will end up losing the first word!

If you want to print all words, just lose the $words = array_slice($words, 0, 100);. Read more about array_slice here.
