array_search problem

Zort

Okay, here is what I am trying to do:

take a log.txt file and open it into an array.
txt file looks like this.

3213 login 23:04
1112 login 23:09
3211 logout 00:09
1344 login 01:09
3213 logout 01:12

then search the array for lines containing the user '3213' and display them to show that users activity. This is the code I have got so far:

$array = file('log.txt');
$search_for = 3213;
$key = array_search($search_for, $array);
print $array[$key];

unfortunately this only returns the first entry it comes across and I need it to print all the lines that include user 3213. I understand I probably have to use a loop here but have no idea how to do that properly in this case.

Thanks for reading

$array = file('log.txt');
$search_for = 3213;

while($key = array_search($search_for, $array))
    print $array[$key]."<br>";

im not sure but i think u need to iterate yr srch...
but im not sure... else u can always do that loop, popping the $key item after printing it...

(its still early, be patient with my english...)

doesn't seem to be printing any output at all - not sure what I'm doing wrong. lol - I'm still guessing at most of this stuff so it could be anything.

alrighty - well, I managed to put together something resembling a script. It returns the result I was looking for but I am pretty sure it's not the best way of doing things 😃 Ah well, it's only my second day learning php...

$count = 0;
$array = file('log.txt'); 
$search_for = 3213; 
$key = array_search($search_for, $array);
while ($count <= 100)
{
$nextkey = stristr($array[$key], '3213');
if ($nextkey == FALSE) { ++$key; }
else
{
print $array[$key]."<br>";
++$key;
};
$count++;}

I'm open to some constructive criticism if anyone wants to let me know what I am doing wrong or how I can make this better. 🙂

lets se..

$array = file('log.txt'); 
$search_for = 3213; 
$key = array_search($search_for, $array);
for($count=0;$count <= 100;$count++)
{
  $nextkey = stristr($array[$key], $search_for);
  if ($nextkey != FALSE) 
     print $array[$key]."<br>";

  ++$key;
}

thats like yr code but it seems to me that array_search isnt used well...

u can do:

$array = file('log.txt'); 
$search_for = 3213; 
foreach($array => $value)
  if (stristr($value, $search_for) != FALSE) 
     print $value."<br>";

this returns the lines in log.txt which contain $search_for
