Unsure about somethings when it comes to arrays

[system]

So yea I am having issues when it comes to inserting something into an array…

$trimmed = file(‘data.txt’, FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
$data = array();
foreach ($trimmed as $line_num => $line) {
if (!$line == “”) {
$split_1 = explode(’[’, $line);
$split_2 = explode(’]’, $split_1[1]); #Grabs Time
$split_3 = explode(’:’, $split_2[1]); #Cleans
$split_4 = explode(’|’, $split_3[2]); #Status
$split_5 = explode(’/’, $split_4[2]); #Overall Players
$data_time = $split_2[0]; #Time
$data_name = $split_3[1]; #Server Name
$data_status = $split_4[1]; #Status
$data_players = $split_5[0]; #Current Players
if ($data_name == " Factions") {
$data[] = $data_time => $data_players;
}
}
}

The part in bold is where i run into my problem I am not sure how to do that. Any help at this point would be amazing. Thanks ahead of time.

[php]$data_time => $data_players;[/php]

This is a key => value pair.

If you are familiar with associative arrays, it is the equivalent to this:
[php]$_POST[‘name’]; // holds the value for an input with the name, ‘name’[/php]

ok well let me explain my situation a bit better…

I am working on a data collector thing and all the data goes to the file.

I then need to extract out the bits I am wanting to put on a graph

Graph code (some random one I found online seems to work the way I want it to)

<?php
# ------- The graph values in the form of associative array
$values=array(
    "Jan" => 2,
    "Feb" => 5,
    "Mar" => 5,
    "Apr" => 5,
    "May" => 5,
    "Jun" => 7,
    "Jul" => 5,
    "Aug" => 5,
    "Sep" => 5,
    "Oct" => 5,
    "Nov" => 5,
    "Dec" => 5,
    "Rob" => 5,
    "Deb" => 5,
    "And" => 5
);

$img_width=500;
$img_height=600;
$margins=20;


# ---- Find the size of graph by substracting the size of borders
$graph_width=$img_width - $margins * 2;
$graph_height=$img_height - $margins * 2;
$img=imagecreate($img_width,$img_height);


$bar_width=20;
$total_bars=count($values);
$gap= ($graph_width- $total_bars * $bar_width ) / ($total_bars +1);


# -------  Define Colors ----------------
$bar_color=imagecolorallocate($img,0,64,128);
$background_color=imagecolorallocate($img,240,240,255);
$border_color=imagecolorallocate($img,200,200,200);
$line_color=imagecolorallocate($img,220,220,220);

# ------ Create the border around the graph ------

imagefilledrectangle($img,1,1,$img_width-2,$img_height-2,$border_color);
imagefilledrectangle($img,$margins,$margins,$img_width-1-$margins,$img_height-1-$margins,$background_color);


# ------- Max value is required to adjust the scale	-------
$max_value=200;
$ratio= $graph_height/$max_value;


# -------- Create scale and draw horizontal lines  --------
$horizontal_lines=50;
$horizontal_gap=$graph_height/$horizontal_lines;

for($i=1;$i<=$horizontal_lines;$i++){
    $y=$img_height - $margins - $horizontal_gap * $i ;
    imageline($img,$margins,$y,$img_width-$margins,$y,$line_color);
    $v=intval($horizontal_gap * $i /$ratio);
    imagestring($img,0,5,$y-5,$v,$bar_color);

}


# ----------- Draw the bars here ------
for($i=0;$i< $total_bars; $i++){
    # ------ Extract key and value pair from the current pointer position
    list($key,$value)=each($values);
    $x1= $margins + $gap + $i * ($gap+$bar_width) ;
    $x2= $x1 + $bar_width;
    $y1=$margins +$graph_height- intval($value * $ratio) ;
    $y2=$img_height-$margins;
    imagestring($img,0,$x1+3,$y1-10,$value,$bar_color);
    imagestring($img,0,$x1+3,$img_height-15,$key,$bar_color);
    imagefilledrectangle($img,$x1,$y1,$x2,$y2,$bar_color);
}
header("Content-type:image/png");
imagepng($img);

My problem is now I need to make an array that will fit in with this graph code I found. Is there a way you can help me figure out how to get it to work?

[astonecipher]

This is the part where I say, “What exactly are you having trouble with?”

The graph code works, the key => value array comes in on line 3 - 19. What have you tried to modify and what are you expecting as a result?

also I know the graph code works…

I want to generate a array to use with that graph but unsure how to go about creating a key value array from a text file?
