I have an array that I pull that looks like this:
[157966745,275000353,43192565,305328212]...
How do I go about taking that "string" and converting it to a PHP array which I can then manipulate.

You have an array which you want to convert to... an array also?ecchymose– ecchymose2011-06-01 20:18:55 +00:00Commented Jun 1, 2011 at 20:18

PHP doesn't accept that format as an array, so yes.switz– switz2011-06-01 20:21:21 +00:00Commented Jun 1, 2011 at 20:21

Where does this come from? Is it really a string? If so, you should rename your question.Felix Kling– Felix Kling2011-06-01 20:23:01 +00:00Commented Jun 1, 2011 at 20:23

This looks like JSON, so you can use json_decode:
$str = "[157966745,275000353,43192565,305328212]";
$data = json_decode($str);

@Switz: You're welcome. Note that this will only work if you have numeric values. Strings values would have to be enclosed in double quotes.

In this context,
json_decode() will produce an array of integers whereas explode() will create an array of strings.$s = "[157966745,275000353,43192565,305328212]";
$matches;
preg_match_all("/\d+/", $s, $matches);
print_r($matches);

With exact that code...
$string='[157966745,275000353,43192565,305328212]';
$newString=str_replace(array('[', ']'), '', $string); // remove the brackets
$createArray=explode(',', $newString); // explode the commas to create an array
print_r($createArray);

PHP explode is built just for this.
$result = explode(',', $input)

What about the square brackets?

...the first and last elements get braces included as "bonus" characters.
The answer by @Felix Kling is much more appropriate given the context of the question.
$new_string = preg_replace('/([\[|\]])/', '', $strarr);
$new_array = explode(',', $new_string);`

There is no benefit to using capture groups when you are replacing the whole string. Character classes must not contain pipes with the intention to delimit characters inside the expression.
