Remove double quotes from json array and fix link - php

Question

Hi i have this code to output a array list
$Sql1 = "SELECT * FROM tabmp3
WHERE Mp3_Player = 1
";
$Query1 = mysql_query($Sql1, $Conn)or die(mysql_error($Conn));
$musicas = array();
while($Rs1 = mysql_fetch_array($Query1)){
$musicas[] = array( title => $Rs1['Musica_Nome'], autor => "Grupo Fronteiras", mp3 => "http://site/Musicas/".$Rs1["Disco_Id"]."/".$Rs1["Musica_Mp3"] );
}
echo ( json_encode($musicas) );
this output
[{"title":"Alegria do Pov\u00e3o","autor":"Grupo Fronteiras","mp3":"http:\/\/site\/Musicas\/3\/201302140204413c390efdb9957eebd8d85c262f2a4929.mp3"}, {"title":"Bem na moda da fronteira","autor":"Grupo Fronteiras","mp3":"http:\/\/site\/Musicas\/2\/20130214032235fabd12471ffc7790c9204f891919bca8.mp3"}]

Answer 1

Try this..I know it is not very good way to do it.. I am writing this to show you that you have to make the form that you wanted in your php code only.
$json = json_encode($musicas);
$json = preg_replace('/["]/', '' ,$json);
$json = str_replace(':',':"', $json);
$json = str_replace(',','",',$json);
$json = str_replace('}]','"}]',$json);
echo $json;
By this way you will acheive what you wanted. But please find something good way to do it.
The correct answer should be this, as commented by #AlvaroLouzada
$json = json_encode($musicas);
$json = preg_replace('/"([^"]+)"\s*:\s*/', '$1:', $json);
echo $json ;

I looked a lot for an elegant solution to fix this issue without doing changing things over javascript or just replace quotes via preg_replace (for the case that the values would contain quotes) and end up doing it by myself. even if it's too late, I hope it would help those who are looking for the same solution.
function json_encode_advanced(array $arr, $sequential_keys = false, $quotes = false, $beautiful_json = false) {
$output = "{";
$count = 0;
foreach ($arr as $key => $value) {
if ( isAssoc($arr) || (!isAssoc($arr) && $sequential_keys == true ) ) {
$output .= ($quotes ? '"' : '') . $key . ($quotes ? '"' : '') . ' : ';
}
if (is_array($value)) {
$output .= json_encode_advanced($value, $sequential_keys, $quotes, $beautiful_json);
} else if (is_bool($value)) {
$output .= ($value ? 'true' : 'false');
} else if (is_numeric($value)) {
$output .= $value;
} else {
$output .= ($quotes || $beautiful_json ? '"' : '') . $value . ($quotes || $beautiful_json ? '"' : '');
}
if (++$count < count($arr)) {
$output .= ', ';
}
}
$output .= "}";
return $output;
}
function isAssoc(array $arr) {
if (array() === $arr) return false;
return array_keys($arr) !== range(0, count($arr) - 1);
}
usage:
$array = [
'someField' => '"value"', // double quotes for string if needed
'labelField' => '"label"', // double quotes for string if needed
'boolean' => false,
'numeric' => 5,
'render' => [
'option' => 'function() {
console.log("Hello World!");
console.log(\'Hello World!\');
}',
],
];
echo json_encode_advanced($array);
result:
{
someField : "value",
labelField : "label",
boolean : false,
numeric : 5,
render : {
option : function() {
console.log("Hello World!");
console.log('Hello World!');
}
}
}

Instead of doing echo ( json_encode($musicas) );, do something like this:
$json_string = json_encode($musicas);
$json_string = str_replace('\/', '/', $json_string);
echo $json_string;
