[SOLVED] Show only the lines starting with "a" or "b" or...(possible?)

[willdk]

Can php show the lines starting with "a" from my file fellow-students.php ?

[rhodesa]

foreach(file('fellow-students.php') as $line){
  if(substr($line,0,1) == 'a')
    echo $line;
}

Rhodesa, thank you for that script. I love it

 

I have two issues

a) I want to shuffle the list so people won't see the same lines every day

b) Because the list contains duplicate lines I want only unique lines to show

 

I hope the script can be changed to get this result :-\

[rhodesa]

$lines = file('fellow-students.php');

//Eliminate duplicates
$lines = array_unique($lines);

//Filter on 'a'
$_lines = array();
foreach($lines as $line){
  if(substr($line,0,1) == 'a')
    $lines[] = $line;
}
$lines = $_lines;
unset($_lines);

//Mix it up
shuffle($lines);

//Show them
print implode("\n",$lines);
