14,604 PointsFile Handling with PHP
Why this is not correct (Challenge Task 2 of 3) ?
<?php $files = scandir('example');
foreach($files as $file){ echo '<h3>'; if(substr($file, 0,3) == 'fun'){ echo $file; } echo '</h3>'; }
<?php
$files = scandir('example');
foreach($files as $file){
echo '<h3>';
if(substr($file, 0,3) == 'fun'){
echo $file;
}
echo '</h3>';
}

, but files that contain fun
anywhere in the name. Using the strpos()
function makes the most sense in this case, not the substr()
function.
if (strpos($file, 'fun') !== false) {
// do something with $file
}
You also have to make sure that you're only echoing out the H3
tags inside your conditional check, otherwise the H3
tags will printed out, even though the condition isn't true.
