I am trying to generate JSON using PHP, and I'm having some issues. I need to iterate through all the images in a folder, and post the json to an API. I'm almost there, but JSON not formatting correctly.
What I want to acheive is this
{
"md": {
"title": "Title"
},
"pageList": {
"pages": [
{
"fileName": "001.jpg",
"pageNr": 1
},
{
"fileName": "002.jpg",
"pageNr": 2
}
]
}
}
and so on for each page.
I am almost there, but it is not formatting correctly, and I am getting \n newline characters in my output:
Here's my code:
<?php
function json_generate() {
$title="Title";
// on my system: produces an array of files in a directory (working correctly)
// $files = array_diff(scandir(__DIR__ . "/images"), array('.', '..'));
//
// below code for testing:
$files = array('001.jpg','002.jpg');
$files_array = array();
foreach($files as $file) {
$i=0;
$pgNo=$i+1;
$addToArray=array (
$i =>
array (
'fileName' => "$file",
'pageNr' => $pgNo,
)
);
array_push($files_array, $addToArray);
}
$json_array=array (
'md' =>
array (
'title' => "$title",
),
'pageList' =>
array (
'pages' =>
json_encode($files_array, JSON_PRETTY_PRINT),
),
);
$json_pretty = json_encode($json_array, JSON_PRETTY_PRINT);
echo $json_pretty;
}
json_generate();
?>
