Php to javascript

[KidSeven]

Hi everyone,

I am new to php builders so I think I have the privilege to ask silly questions... just to test how this works hehe. Well this may sound silly to most of you but I have no idea how its really done.

So here's my silly question... I would like to create an array variable in php and I would like to pass this array to a javascript so that I may use it latter if a user asks for it.

I did not even try this but imagine it would be something like this...

<?php
$a=array('a' => 'hello', 'b' => 'php', 'c'=> 'builders');
?>

<script language="JavaScript">
function Get_Array()
{
My_array= new array()
My_array=<?php echo $a; ?>
}
</script>

try [man]var_export/man instead of echo.

<script language="JavaScript">
function Get_Array()
{
My_array= new array()
<? for($b=0;$b<count($a);$b++) {
pritnt "My_array[$b]= $a[$b];";
}
?>
}
</script>

Thanks TTT,
You posted:
<script language="JavaScript">
function Get_Array()
{
My_array= new array()
<? for($b=0;$b<count($a);$b++) {
pritnt "My_array[$b]= $a[$b];";
}
?>
}
</script>

So as a newby I tried it out. I copied and pasted what you gave to my script and it didnt work....aaaarrrggggg hehe...

First the spelling "print " that was easy to see...
Then I found out that new array must be spelled "new Array" in the javascript...
Then found out that there was no ( \" ) inside the php print...

Once all this corrected it still didnt work 😃
My original post asked how to pass the array >>>

<?php
$a=array('a' => 'hello', 'b' => 'php', 'c'=> 'builders');
?>

Since the keys "a,b,c" are not found in your script this will never work...
To make it work the array must be changed or your script. I changed the array to >>>
<?php $a= array("hello","php","builders"); ?>

Now it works correctly aaarrgggg.... hehe

function Get_Array()
{
My_array= new Array()
<? for($b=0;$b<count($a);$b++) {
print "My_array[$b]= \"$a[$b]\";\n";
}
?>

document.write(My_array);
}

Thanks..... next time be aware I am a newby aaagggrrrr... hehe

Hi Moonglobe,
You Posted:
try var_export() instead of echo.

I tried this and found no ways to make it work inside a javascript function, I am a newby so maybe there is a way but I didnt figure it out... if you know how, I would be glad to see how its dont....

I tried this...

</script>
<script language="JavaScript">
function Get_Array()
{

My_array= new Array();
MY_array=<? var_export($a)?> ;

document.write(My_array);
}

</script>

... javascript doesnt seem to know more than I what I was trying to do aaarrrggg...hehe

Step back out of the problem for a second. Why use javascript for the array in the first place (not everyone allows js). Why not keep it in php and use it when you need to?

[KidSeven]

Simply because the page must be refresh each time you need the php information. While if its placed in a javascript you may have access to it at any time and for any amounts of hits needed, without a page refresh. :o

...it didnt work....aaaarrrggggg...
...Now it works correctly aaarrgggg...
...I am a newby aaagggrrrr...

😃 😃 😃 and are you a pirate, as well? 😃 😃 😃

[KidSeven]

No, its just that I selected the newbies thread, because I am a newby.

I thought I would get replies from people who would make sure that the information they were giving me was tested...... but this doesnt seem the case. Now I understand that I should post in a more advance thread... aaaggggrrrr 😃

[Shrike]

No it's not a difficult problem, you picked the correct forum 🙂

$array = array ( 'a' => 'pirates',
              'b' => 'say',
              'c' => 'aaaaagr'
);
echo "<script language=\"javascript\">\nmyarray = new Array()\n";
$i = 0;
foreach($array as $key => $value){
  echo "myarray[$i] = '$value'\n";
  $i++;
}
echo"
for(i=0;i<myarray.length;i++){
  document.write(myarray[i]+\"\\\n\")
}</script>";

Shrike,

In your post you said... "No it's not a difficult problem, you picked the correct forum".

What I was complaining about is that those who post dont seem to try the examples they send... because if they did... they would easily see that they dont work and it would make US "newbies" much less frustrated if they would send working examples.....

The example you sent is full of "ERRORS" ... you certainly didnt try it to see if it worked before posting it.... AAAAAARRRRRRGGGGGG ... hehe

😃

some people have lives. we don't always have time to test code we write of the top of our heads. i realize now that the JS syntax for arrays is different rom PHP's... try (note the use of try 😉) this:

<script language="JavaScript">
function Get_Array()
{

My_array=
<?php
ob_start();
var_export($a);
echo str_replace('array','new Array',ob_get_contents());
ob_end_clean();
?> ;

document.write(My_array);
}

</script>

Hi Moonglobe,

Thanks for having taken the time to post to this thread.

You wrote: "... try (note the use of try ) this:"

Well I did try everything that was posted to me... the ones that didnt work I played with them until I got them to work but with lots of frustration but lots of fun too...

The first post you sent was interesting because it had a function that seemed to do all the work for us "var_export($a);" but after having played with it in many different way I figured it was just a php view function used to debug array problem... but I thought that maybe some people may have used it to insert arrays in javascript... that could have been fun hehe...

Was easy to try your script... here is the result..

Would need a few more lines of php script to make this work, so I think the "echo" is still the best and fastest way .... hehe

<script language="JavaScript">
function Get_Array2()
{

My_array= new Array();
MY_array=array(3) {
[0]=>
string(5) "hello"
[1]=>
string(3) "php"
[2]=>
string(8) "builders"
}
;

document.write(My_array);
}

</script>

Huh? I just copied and pasted my example direct from the board into Textpad and it works (in IE, probably not in NS due to invalid HTML)....are you testing in in ASP or something? 🙂

By the way I just tested your last example, and get "Expected ; at line 6". Also you don't ever call your function so are never going to get any output. Finally, it's not even PHP. Perhaps you should do as you say before posting.

Sorry if I have offended you in any ways, when I said your script is full of ERRORS.... 😕 I must admit I copied it inside a javascript function hehe.... I hadnt noticed that you echoed the javascript tags..... MY MISTAKE .... aaaaaggggrrrrrr hehe

As for the second part of your post... I have no idea what you are taking about... the only script I posted are the ones that were sent to me... 😃 , so if they dont work.... dont blame me lol
