I have a json array:
[ { "var1": "9", "var2": "16", "var3": "16" }, { "var1": "8", "var2": "15", "var3": "15" } ] How can I loop through this array using php?

Show activity on this post. foreach ($array as $key => $jsons) { // This will search in the 2 jsons foreach($jsons as $key => $value) { echo $value; // This will show jsut the value f each key like "var1" will print 9 // And then goes print 16,16,8 ... } } If you want something specific just ask for a key like this.
Use the foreach($array_name as $element) to iterate over elements of an indexed array. Use the foreach($array_name as $key => $value) to iterate over elements of an associative array.
A JSON array is produced by assigning a contiguous integer-indexed PHP array into a JSON domain tree path. A PHP array variable is contiguous integer-indexed if it contains only integer keys that are sequenced from 0 to n -1 (where n is the total number of items in the array).
Decode the JSON string using json_decode() and then loop through it using a regular loop:
$arr = json_decode('[{"var1":"9","var2":"16","var3":"16"},{"var1":"8","var2":"15","var3":"15"}]'); foreach($arr as $item) { //foreach element in $arr $uses = $item['var1']; //etc } Set the second function parameter to true if you require an associative array
Some versions of php require a 2nd paramter of true if you require an associative array
$json = '[{"var1":"9","var2":"16","var3":"16"},{"var1":"8","var2":"15","var3":"15"}]'; $array = json_decode( $json, true ); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
