I've got an array of arrays called $jsonvpr. When trying to pull a preg_grep like preg_grep("/Jake.*.Peavy/i", $jsonvpr) it returns Notice: Array to string conversion in /var/www/html/crawlnew.php on line 310 a bunch of times (I supose once per entry on the array) and it don't return anything. I suspect the problem is that there are not just arrays, but arrays of arrays, and that's why it isn't worked as I wanted, but I don't know how should I do. Please, anyone can point me on the right direction?
A sample of how the array would be:
array(102) {
[0]=>
array(8) {
[0]=>
string(4) "Rank"
[1]=>
string(6) "Player"
[2]=>
string(13) "Games Started"
[3]=>
string(16) "Excellent Starts"
[4]=>
string(14) "Neutral Starts"
[5]=>
string(11) "Poor Starts"
[6]=>
string(12) "Volatility %"
[7]=>
string(3) "VPR"
}
[1]=>
array(8) {
[0]=>
string(0) ""
[1]=>
string(73) "Clayton Kershaw"
[2]=>
string(0) ""
[3]=>
string(0) ""
[4]=>
string(0) ""
[5]=>
string(0) ""
[6]=>
string(0) ""
[7]=>
string(0) ""
}
[2]=>
array(8) {
[0]=>
string(0) ""
[1]=>
string(73) "Felix Hernandez"
[2]=>
string(0) ""
[3]=>
string(0) ""
[4]=>
string(0) ""
[5]=>
string(0) ""
[6]=>
string(0) ""
[7]=>
string(0) ""
}
[...]
You could get all the names into an array first and preg_grep over that:
$names = array_column($jsonvpr, 1);
$foundElements = preg_grep("/Jake.*.Peavy/i", $names);
Where the second argument of array_column, 1, is the index of the array element you want to match.
