I have this simple array and I'd like to know how I can stop the first 2 segments from showing.

if(preg_match_all('/<td[^>]*class="sourceNameCell">(.*?)<\/t开发者_开发知识库d>/si', $printable, $matches, PREG_SET_ORDER));{
foreach($matches as $match) {

$data = "$match[1]";

    $array = array();
    preg_match( '/src="([^"]*)"/i', $data, $array ) ;
    print_r("$array[1]") ;
}

Any help would be great, Thanks!


Use array_slice:

$output = array_slice($input, 2); 


Stop from showing or removing?

for removing:

$array = array();
preg_match( '/src="([^"]*)"/i', $data, $array ) ;

// The following lines will remove values from the first two indexes.
unset($array[0]);
unset($array[1]);
// This line will re-set the indexes (the above just nullifies the values...) and make a     new array without the original first two slots.
$array = array_values($array);
// The following line will show the new content of the array
var_dump($array);

Hope this helps!


Use array_slice($array, 2, count($array)) or make your regexp skip the first two if possible.

You could also invoke array_shift() twice on the array. This might be more optimal since it shouldn't need to make a copy of the array.


You could use array_splice to remove elements from array.

array_splice — Remove a portion of the array and replace it with something else

Elements are removed from original array and returned

$input = array("red", "green", "blue", "yellow", "black");
$part = array_splice($input, 1, 2);
var_dump($input);
var_dump($part);
