Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system
is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.

When one aligns the code posted on 2011-10-04 13:49 UTC properly, we get the
following code:
----------------------------------------------
<?php
$fil_in = "test_new.php";
$fil_out = "test2.php";
if ( file_exists($fil_in)) {
$file_in = fopen($fil_in,"r+");
$file_out = fopen($fil_out,"w+");
}
while(!feof($file_in)) {
$line_in = fgets($file_in);
$line_array = explode(">",$line_in);
}
$j=count($line_array);
for ($i=0; $i< ($j-1); $i++) {
$line_out = $line_array[$i];
fwrite($file_out, $line_out.">"."\n");
}
fclose($file_in);
fclose($file_out);
----------------------------------------------
This shows clearly that only the last line of the source file will be written to
the destination file.
I think this just happens to be near a "<?php" in the file.
Thus not a bug in PHP, but in the code supplied.
Recommendation:
Closing as "not a bug".
Sidenote:
Intended result can be achieved with:
file_put_contents('test2.php', str_replace(">", ">\n",
file_get_contents('test_new.php'));

The test_new is originally a html file with php.code inside, and have been
trimmed by the trim function to get rid of the blanks.
The outcome is that test2.php should contain ALL the information in the
test_new.php changed by the explode to have one html kommand per line.

The test2.php is the result of explode test_new.php.

What contain "test_new.php" and "test2.php"? And what are the expected and
actual
results?
