print_r + writing array to a file

yuda_zdk

I used print_r in this way

$str = print_r($array_input, true) ; // $str is a string

Then I wrote $str into a file

fwrite($fp, $str) ; // $fp is the file handler

The problem is that the boolean parameter (second paramater)
of print_r is valid only since php version 4.3.0 whilst the server
php version is: 4.1

What other choice do I have to write an array into a file ?

Thanks and regards

What have you tried so far that didn't work?

Hmm... maybe try something like this:

<?php
// array
$array = array(1,2,3,4,5,6,7,8,9,0);

// start string to add to file:
$str = '<?php' . "\n";
$str .= '$array = array(';
foreach($array as $value){
	$str .= '\'' .  $value . '\',';
}
$str .= ');' . "\n";
$str .= '?>';

// write to file:
$file = 'test.php';
$fp = fopen($file, 'w');
fwrite($fp, $str);
fclose($fp);
?>

Ah.. Rodney beat me to it. Heres a little different way, dont know which one is better.

$t = array('test1','test2',3,4);
ob_start();
print_r($t);
$output = ob_get_contents();
ob_end_clean();

$fp = fopen('arr.txt',"w");
fwrite($fp,$output);
fclose($fp);

$fp = fopen($file, 'w');
fwrite($fp, $str);
fclose($fp);

(this is for writing an array to a .php file)

That is a good solution, cahva.
