looking through two fields for a random item

[11Tami]

Hello, how would I pick an item from these 2 fields randomly, instead of one at a time? For example this picks an item randomly from both $one1 $one2 separately. How can I choose randomly from both of them instead? So that I only have one result at the end instead of 2? Please let me know, thank you very much.

 

<?php 
$one= "<span style='color: rgb(70,0,0)'>test1</span>"; 
$one[3] = "file1.txt"; 
$one1 = preg_grep('/(?:<span)/', $one); 
$one2 = preg_grep('/(?:<span)/', $one, PREG_GREP_INVERT); 
$get1 = $one1[array_rand($one1)]; 
$get2 = $one2[array_rand($one2)]; 
$get3 = file_get_contents($get2); 
echo $get1; 
echo $get3; 
?>

hi,

 

why cann't you use array_rand() again .

$araay=array($get1,$get2);

$final_output=array_rand($araay,1);

 

array_rand() returns the key for a random entry.

i suggest to use

$arr_result=array_merge($one1,$one2);

and use the $arr_result to choose randomly from both of them

Thanks both of you. Priti, what does the 1 do here? I dont know how to try it.

($araay,1);

 

 

I also tried these, this returns the file file1.txt on every page load correctly and never shows the text "test1".

 

<?php 
$one[1] = "<span style='color: rgb(70,0,0)'>test1</span>"; 
$one[2] = "file1.txt"; 
$two1 = preg_grep('/(?:<span)/', $one); 
$two2 = preg_grep('/(?:<span)/', $one, PREG_GREP_INVERT); 
$rand1 = $two1[array_rand($two1)]; 
$rand2 = $two2[array_rand($two2)]; 
$file = file_get_contents($rand2);
$get = $rand1 + $file;
echo $get;
?> 

 

.....This only brings back the word "Array" on every page load and nothing else. Is there anyway I can grab onto both? Please let me know, thank you very much.

 

<?php 
$one[1] = "<span style='color: rgb(70,0,0)'>test1</span>"; 
$one[2] = "file1.txt"; 
$two1 = preg_grep('/(?:<span)/', $one); 
$two2 = preg_grep('/(?:<span)/', $one, PREG_GREP_INVERT); 
$rand1 = $two1[array_rand($two1)]; 
$rand2 = $two2[array_rand($two2)]; 
$file = file_get_contents($rand2);
$get = array_merge($rand1,$file);
echo $get;
?>

Hi,

 

($araay,1);

here 1 specifies how many entries you want to pick.$araay is array and from this array i am trying to  pick randomly any one entery.

 

for more details for this function read http://in2.php.net/array_rand line.

In the code snippet you wrote echo $get; but $get is an array, you can not echo on an arrayname.

 

 

i guess you need write this

 

$final_output=array_rand($get,1); 

echo $final_output;

Thanks a lot you guys, pdkv you lost me that time.

The only $get I see is at the end, the arrays are named something else aren't they? Please let me know, thank you very much.
