How can I get the alt="$ValueIwant" for each with a preg_match

[BlueSkyIS]

something like...

$string = file_get_contents("information.txt");

$pattern = '/alt="(.*)" \//';
preg_match_all($pattern, $string, $matches);
print_r($matches);

[plznty]

How would I print one by one?

[BlueSkyIS]

$matches contains an array of each one. one by one. loop over the appropriate part of $matches to get each value, one by one.

Another example:

 

$str = file_get_contents("information.txt");

preg_match_all('~alt\s?=\s?[\'"](.*?)[\'"]~is', $str, $a);

foreach ($a[1] as $c) {

echo "{$c} <br />";
}
