php split array string into data - php

Question

Below script is shown search string in a text file, my text file has contents like:
60, 1, 1, 188, pdgje5566
60, 1, 1, 188, pdgje5565
if(!empty($extTxId)){
$searchfor = $extTxId;
$matches = array();
$handle = #fopen($file, "r");
if ($handle)
{
while (!feof($handle))
{
$buffer = fgets($handle);
if(strpos($buffer, $searchfor) !== FALSE)
$matches[] = $buffer;
}
fclose($handle);
}
print_r($matches);
it output as
Array ( [0] => 60, 1, 1, 188, ppje5566 )
however i want to explode the data which is separate by comma(,) and store into variable, is that anyway to do it?
thanks.

Answer 1

i want to explode the data which is separate by comma(,)
Use explode().
If this is a CSV file (or some other delimited file), I suggest looking at fgetcsv(). It is effectively fgets() and explode(), which seems to be what you need.

Answer 2

Since you have spaces between each comma, you can trim each element.
// Iterate through each item int the array (you can do $matches[0] if you just want the first)
foreach ($matches as $match)
{
$output_array = array_map('trim',explode(',',$match));
print_r($output_array);
}
Output:
Array
(
[0] => 60
[1] => 1
[2] => 1
[3] => 188
[4] => pdgje5565
)

Answer 3

Try like
foreach(Array[0] as $element)
{
echo $element;
}

Answer 4

If you know the exact structure of the input you're getting, you could do something like:
$string = '60, 1, 1, 188, pdgje5565';
// Using trim just to be sure
list($varA, $varB, $varC, $varD, $varE) = explode(', ', trim($string));
This way you would get the results as follows:
$varA = 60;
$varB = 1;
$varC = 1;
$varD = 188;
$varE = 'pdgje5565';
The main advantage here is you would get decent variables instead of array with abstract indexes, but it is only good if you're sure about you're structure being constant.
