PHP problem with 1D matrix

blackest · April 14th, 2008, 05:22 AM

Hello,
I write a script that looks into a directory, opens every file and reads these files into 1D matrix. Problem is that files have an empty lines.
My question is: how can I remove these empty entries from matrix ?
This is an example 1D matrix with empty entries.

Code:

[data1]
[]
[data2]
[data3]
[]

and here is my php code I use to read from files:

Code:

while($full_info[$i] = fgets ($fd,1024)){
//some code here
$i++;
}

I'll be glad for any help,
Best regards :)

Programmers would normally say array rather than matrix, but if you find that easier to visualise then go for it.

All you need to do is check your line to see if its blank before putting it into your array.

Code:

// slurp into a temporary variable rather than straight into array
while($line = fgets ($fd,1024)){
  // Check that temporary variable is not an empty string
  // If it isn't, put it in array and increment array index
  if($line!=='') {
    $full_info[$i] = $line;
    $i++;
  }
  //some code here
}
