Convert php array to Javascript (19 answers)

Closed 9 years ago.

I have tried to implement PHP array into JavaScript but the problem is that it is not converting properly.

For example if PHP array $new_array has a value of a,q,s,t,u it is assigning to all the indexes of JavaScript array for example:

js_array[0]=a,q,s,t,u;
js_array[1]=a,q,s,t,u;
js_array[2]=a,q,s,t,u;
js_array[3]=a,q,s,t,u;
js_array[4]=a,q,s,t,u;
js_array[5]=a,q,s,t,u;

This is my PHP code:

 $new_array = array(); // create a new array
$sql=mysql_query("SELECT * FROM animate ORDER BY RAND() LIMIT 5") or die("query Field");
 while($row=mysql_fetch_array($sql)){
 $new_array[] = $row['code'];
 }

js code

var array =[<?php echo json_encode($new_array);?>];
 alert(array[0]);
 for(var i=0; i <=9 ; i++)
 {
 array[i]=[<?php echo json_encode($new_array);?>];
 }

I want to assign values like:

array[0]=a;
array[1]=q;
array[2]=s;
array[3]=t;
array[4]=u; 

I want to do in this pattern but it is not working.

• AbraCadaver: What is in $row['code']???
• Marc B: [<?php encode ?>] is creating an array with your encoded array in it, which you then store in ANOTHER array. all you need is var arr = <?php echo json_encode($your_array); ?>
• mod geek: can you answer the question @MarcB with a proper code
• mod geek: not working @MarcB
• Marc B: not workin gHOW? Like I said, if you just want to embed that array of values you built in php to a var in javascript, then ALL you need is the one line I posted above. everything is just creating a bigger array with multiple copies of your from-db array in each element.

Answer 1

You could "implode" it or you could use JSON.

Implode Method

var array = [<?php echo implode($array, ","); ?>];

JSON Method

var array = <?php echo json_encode($array); ?>;

Answer 2

Just iterate the php array inside the js array braces.

var array =[<?php foreach ($newArray as $value) echo "'" . $value . "',"; ?>];

You might have to put an additional line to clip the last ,
