[SOLVED] Simple For loop with variable eval() issue.... please help.

[shlomikalfa]

hey,

i am trying to create a loop 1 to 5, that will compare two variables, one of them is easy since it's a global and i can use the brackets. but the other one doesn't have it... what should i do ?!

 

for ($i = 1; $i <6; $i++){
	echo $MyGlobalVar['VarID'.$i]."<br />";
	echo eval('$Var'.$i.'_ByID')."<br />";
}

 

Thanks in advance.

Going to need to see more of your code to understand what you mean. Notice that '$Var' will print the literal string '$Var' and not interpolate the variable.

I don't see what isn't understood in my question... i was just wanting to know how will i make that work... seems quit an explained to me...

 

$MyGlobalVar['VarID1'] = "My name is here";
$MyGlobalVar['VarID2'] = "2nd Name";
$MyGlobalVar['VarID3'] = "3rd thing";
$MyGlobalVar['VarID4'] = "4th.";
$MyGlobalVar['VarID5'] = "5th.";
$Var1_ByID = "This is something too";
$Var2_ByID = "This is something too2";
$Var3_ByID = "This is something too3";
$Var4_ByID = "This is something too3";
$Var5_ByID = "This is something too1212123";

   for ($i = 1; $i <6; $i++){
      echo $MyGlobalVar['VarID'.$i]."<br />";
      echo eval('$Var'.$i.'_ByID')."<br />";
   }
</code]

I think this should echo all of the variables.... but it does echo only the fist echo... the 2nd one launches a warning....
hope it's better understood.....

Instead of using variables, you should consider using an array. Its easier to read and faster.

 

Anyway....

 

for ($i = 1; $i <6; $i++){
  echo $MyGlobalVar['VarID' . $i] . "<br />";
  echo ${'Var' . $i . '_ByID'} . "<br />";
}
