Below is the code. I have commented out alot of it because I am trying to figure out what is going on. I am reading a file in and based on that file I read in a bunch more. When I read in lines from the file data is being changed. Below is an example file:

Time,209,XACC,0.04,YACC,0.86,ZACC,0.19,XSHOCK,0.58,YSHOCK,0.45,ZSHOCK,0.06,Position,standing

Time,240,XACC,0.4,YACC,0.87,ZACC,0.99,XSHOCK,0.25,YSHOCK,0.83,ZSHOCK,0.38,Position,standing

The php read it in and I get an echo of this on one line Time,0,XACC,0.41,YACC,0.67,ZACC,0.34,XSHOCK,0,YSHOCK,0.69,ZSHOCK,0.24,Position,standing

It is changing the time values for some reason. This does not make sense to me.
[php]

<?php $q = $_REQUEST['q']; $devices = file_get_contents("devices.txt"); $dparts = explode("\n", $devices); $string = ""; for($i = 0; $i < count($dparts); $i++) { $typelist = explode(',', $dparts[$i]); if($typelist[0] == $q) { for($j = 1; $j < count($typelist); $j++) { //$string = $string.$typelist[$j]; //$string = $string.","; $readfile = $typelist[0]."_".$typelist[$j].".txt"; $readfile = preg_replace('/\s+/', '', $readfile); $file = file($readfile); if(count($file) >= 5) { for($k = count($file) - 5; $k < count($file); $k++) { echo $file[$i]; //if($k < count($file) - 1) //{ // $string = $string."("; //} } } else { for($k = 0 ; $k < count($file); $k++) { //$string = $string.$file[$i]; //if($k < count($file) - 1) //{ // $string = $string."("; //} } } //if($j != count($typelist)-1) //{ // $string = $string.":"; //} } } } //$string = preg_replace('/\s+/', '', $string); //echo $string; ?>

What are you trying to do with the data? I see it being read, but its not doing anything that I can see.

As for the echo issue, remember, you’re dealing with a rather large array. Anything that needs to be pulled out has to be put into a other array, then read outside of the original loop. you can also look through the array functions on php.net.
