what you're trying to do is quite simple:

collapse the multi-line records into a single line
split the lines into an array

pretty much:

<?php
$string = 'aaa  1111111,
    2hajakka,
    87uj5687,
     F2tryty   
bbb  45454545,
    rereer,
    87uj5687,
     4343343,
    944dsdds';

// move lines beginning with a space to the previous line
$string = preg_replace('#\n +#', ' ', $string);
// split lines into array
$array = explode("\n", $string);
var_dump($array);

urm, what? I have no clue what the meaning of 944dsdds is, I don't know if the space preceeding ` 4343343` has any relevance and if so, what it means. Nor do I know why rereer is one character shorter than the other keys (without a preceeding or trailing space). If all that has any meaning, please elaborate. Otherwise it just looks like badly formatted text.

$file_handle = fopen("myfile.txt", "r");
$arr[] = "";
$i = 0;
$temp_string = '';

while (!feof($file_handle)) {
$line = fgets($file_handle);
if(strpos($line,",")!== false)
{
$temp_string = $temp_string.$line;}
else{
$temp_string = $temp_string.$line;  
$arr[$i] = $temp_string;
$temp_string = '';
$i++;}
}
