How to concatenate PHP variable name?

Question

I have a PHP for loop:

for ($counter=0,$counter<=67,$counter++){  echo $counter; $check="some value";  } 

What I am trying to achieve is use the for loop variable and append it to the name of another variable.

Bascially, I want the PHP output to be as follows for each row

1 $check1="some value"  2 $check2="some value"  3 $check3="some value"  4 $check4="some value"  etc etc  

I have tried $check.$counter="some value" but this fails.

How can I achieve this? Am I missing something obvious?

Answer 1

The proper syntax for variable variables is:

${"check" . $counter} = "some value"; 

However, I highly discourage this. What you're trying to accomplish can most likely be solved more elegantly by using arrays. Example usage:

// Setting values $check = array(); for ($counter = 0; $counter <= 67; $counter++){     echo $counter;     $check[] = "some value"; }  // Iterating through the values foreach($check as $value) {     echo $value; } 

Answer 2

You should use ${'varname'} syntax:

for ($counter=0,$counter<=67,$counter++){     echo $counter;     ${'check' . $counter} ="some value"; } 

this will work, but why not just use an array?

$check[$counter] = "some value";
