Get 2 contents per line - php

Question

I was wondering I can get these to the ID and the Name from this code:
stuffyd[1] = {name: "Item 1"};
stuffyd[2] = {name: "Item 2"};
stuffyd[3] = {name: "Item 3"};
stuffyd[4] = {name: "Item 4"};
stuffyd[5] = {name: "Item 5"};
stuffyd[6] = {name: "Item 6"};
The ID is in the [IDHERE] and the name, obviously is after name:
I tried using explode and loops but that didn't work out well. Here was my code:
<?php
function getItemName($i) {
$itemNameFile = file_get_contents('test.txt');
$itemName = explode('"', $itemNameFile);
return $itemName[$i];
}
function getItemID($i) {
$itemIDFile = file_get_contents('test.txt');
$itemID1 = explode('stuffyd[', $itemIDFile);
$itemID = explode(']', $itemID1[$i]);
return $itemID[0];
}
function getNamesID() {
for($i = 1; $i < 6; $i++) {
//if ($i & 1) {
$itemName1 = getItemName($i);
//}
//if($i < 6) {
$itemID1 = getItemID($i);
//}
}
echo $itemName1 . ":" . $itemID1 . chr(10);
}
getNamesID();
?>
This is the output:
Item 3:5
What can I do?

Answer 1

// read the file once only
$data = file_get_contents('test.txt');
// use preg_match_all to parse the data
preg_match_all("/stuffyd\[([0-9]+)\].*\"(.*?)\"/im", $data, $matches);
// you could echo here but let's convert the matches into a usable array
$count=count($matches);
for ($i=0; $i<$count; $i++){
$items[$matches[1][$i]]=$matches[2][$i];
}
// and then echo out the key and value of each pair
foreach ($items as $id => $name){
echo $name . ':' . $id . chr(10);
}

The answers by #Popnoodles and #Barmar are best using preg_match_all.
But to understand why your code didn't work, there are 3 issues.
(1) in function getItemName($i) when you explode $itemNameFile the array in $itemName look like -
Array
(
[0] => stuffyd[1] = {name:
[1] => Item 1
[2] => };
stuffyd[2] = {name:
[3] => Item 2
[4] => };
stuffyd[3] = {name:
[5] => Item 3
[6] => };
stuffyd[4] = {name:
[7] => Item 4
[8] => };
stuffyd[5] = {name:
[9] => Item 5
[10] => };
stuffyd[6] = {name:
[11] => Item 6
[12] => };
)
So you need to do
return $itemName[$i+($i-1)];
(2) in function getNamesID() you are only looping through 5 time
for($i = 1; $i < 6; $i++)
to get all 6 you need to use <=6
for($i = 1; $i <= 6; $i++)
(3) in function getNamesID() your echo ... is outside of your for() loop, so you will only get the last instance. Move the for() loop closing bracket to after your echo -
echo $itemName1 . ":" . $itemID1 . chr(10);
} // end for()
} // end function
So now your code would look like -
<?php
function getItemName($i) {
$itemNameFile = file_get_contents('test.txt');
$itemName = explode('"', $itemNameFile);
return $itemName[$i+($i-1)];
}
function getItemID($i) {
$itemIDFile = file_get_contents('test.txt');
$itemID1 = explode('stuffyd[', $itemIDFile);
$itemID = explode(']', $itemID1[$i]);
return $itemID[0];
}
function getNamesID() {
for($i = 1; $i <= 6; $i++) {
$itemName1 = getItemName($i);
$itemID1 = getItemID($i);
echo $itemName1 . ":" . $itemID1 . chr(10);
}
}
getNamesID();
?>

$contents = file_get_contents("test.txt");
preg_match_all('/stuffyd\[(\d+)\].*=name:\s*"(.*)"/', $contents, $matches, PREG_SET_ORDER);
foreach ($matches as $match) {
echo $match[2] . ':' . $match[1] . "\n";
}
