I have following example PHP code and its working great! but i just want one more addition so it print line number too.
<?php
$path = shell_exec('cat data.txt');
$path = chop($path,"\n");
$lines = explode("\n",$path);
echo "<h2><a href=\"http:\"\" title=\"Summery\">List of Studies</a></h2>";
foreach($lines as $line) {
echo "<h3><p>$line</p></h3>";
}
?>
Output:
ABC
XYZ
123
I want following addition and add counter in it.
1. ABC
2. XYZ
3. 123
You can assign the index to variable too, not just the value:
foreach($lines as $index => $line) {
printf('<h3><p>%d. %s</p></h3>', $index + 1, $line);
}
{$index+1} would work inside a string
0 :(printf('<h3><p>%d. %s</p></h3>', $index + 1, $line); did magic :)
<ol> tag answer, you sir are a fool!If you don't want to use the index php, you can use the tag ol

hell you doing here...$i=1;
foreach($lines as $line) {
echo "<h3><p>$i. $line</p></h3>";
$i++;
}
<?php
$path = shell_exec('cat data.txt');
$path = chop($path,"\n");
$lines = explode("\n",$path);
echo "<h2><a href=\"http:\"\" title=\"Summery\">List of Studies</a></h2>";
$c = 0;
foreach($lines as $line) {
$c++
echo "<h3><p>".$c.". ".$line."</p></h3>";
}
?>

foreach($lines as $i=>$line) {
echo "<h3>$i. <p>$line</p></h3>";
}
filefunction? It will automatically split lines for you
