Read from JSON file with PHP and Multiple foreach statements - php

Question

I tried to read from a JSON file using PHP. But I am stuck now.
This is my JSON file :

And this is my PHP so far:
$str = file_get_contents($url);
$json = json_decode($str, true);
$date = $json['date'];
$leagues = $json['leagues'][0];
foreach ($leagues as $key => $value) {
for ($i=0; $i<count($value); $i++) {
foreach ($value[$i] as $key1 => $value1) {
$sql = "INSERT INTO table_name (column1,column2,column3,column4) VALUES (...,...,...,...)";
for ($c=0; $c<count($value1); $c++) {
foreach ($value1[$c] as $key2 => $value2) {
echo $value2;
}
}
}
}
}
the problem how can read all each array by foreach and store every value to table in database.
I would appreciate an example for this.

Answer 1

Basic structure to loop all nodes in your json
//leagues level
foreach ($json['leagues'] as $key => $league) {
$league_id = $league['league_id'];
//leagues -> league_matches level
foreach ($league['league_matches'] as $key => $match) {
$match_id = $match['match_id'];
//channel ids
foreach ($match['channels_id'] as $channels_id) {
//$channels_id;
//create an sql
$sql = "INSERT INTO xy (col1,col2,col3) values ($league_id,$match_id,$channels_id)";
$db->query($sql);
}
}
}
About the SQL You dont show any structure of your databse, so i cant help creating the sql.

Answer 2

I hope your JSON file sends the value using json_encode() method. You need to separate the array elements with a comma (,). Also you need to write the array indexes within quotes ('). Here is a corrected sample of your JSON page.
$retArr = Array
(
['date'] => 25-1-2017,
['leagues'] => Array
(
[0] => Array
(
['league_id'] => 0,
['league_name'] => كأس امم افريقيا,
['league_logo'] => http://3.bp.blogspot.com/-4iampWUCLto/VmldL2XTz7I/AAAAAAAAD0I/eZFfzSxRbnE/s60/africa.png,
['league_matches'] => Array
(
[0] => Array
(
['match_id'] => 1,
['team1logo'] => http://2.bp.blogspot.com/-mycTzHXuzJA/Ugbb-UG_3JI/AAAAAAAAEv0/_mzaSHnRedE/s60/egypt+(4).png,
['team2logo'] => http://1.bp.blogspot.com/-kYrkU4jahZY/UgbeVpHf8RI/AAAAAAAAFIQ/TBgM5fvVW14/s60/ghana+(3).png,
['match_time'] => 19:00
['channels_id'] => Array
(
[0] => 18
)
['team1'] => مصر ,
['team2'] => غانا
)
)
)
)
);
echo json_encode($retArr);
On the receiving page, you need to set a second parameter to TRUE in the json_decode() method so that you will get the result as an array rather than as a JSON Object.
$str = file_get_contents($url);
$json = json_decode($str, true);
$date = $json['date'];
$leagues = $json['leagues'][0];
foreach ($leagues as $key => $value) {
for ($i=0; $i<count($value); $i++) {
foreach ($value[$i] as $key1 => $value1) {
$sql = "INSERT INTO table_name (column1,column2,column3,column4) VALUES (...,...,...,...)";
for ($c=0; $c<count($value1); $c++) {
foreach ($value1[$c] as $key2 => $value2) {
echo $value2;
}
}
}
}
}
Try this way.
