PHP - 变量变量或变量数组（）用于（）

Question

I have this code that generates an HTML table with php:

<?php 
include("numbers2.php");

echo '<table border="1">';
 echo '<tr>';

for ($i = 1; $i <= 9; $i++) {
if($a1_pos_txt !== TRUE) {

echo "<td>" . $numbers["a" . $i . "_pos"] . "</td>";

} else {?> 
<?php 
echo '<td><input type="text" name="a' . $i . '_post" size="1" maxlength="1" /></td>';
?>
<?php } }?>

What I need to do is modify the $a1_post_txt variable so that it when the foor loops I will get instead of $a1_pos_txt every time:

$a1_pos_txt
.
.
$a9_pos_txt

I it basically what I did with $numbers["a" . $i . "_pos"] and with name="a' . $i . '_post" but now that the variable is inside another variable I don´t know how to do this.

I hope it is clear enough, if no please ask for any clarifications needed.

Thanks in advance!!

Answer 1

Instead of variable use array. In your array will contain values like true or flase, which were earlier in $a1_pos_txt......$a9_pos_txt

$arrOfValues[1] = TRUE;
$arrOfValues[2] = FALSE;
 ......
 .....
 ...
$arrOfValues[9] = TRUE;

So code will look like this

<?php 
include("numbers2.php");

 echo '<table border="1">';
  echo '<tr>';

for ($i = 1; $i <= 9; $i++) {
if($arrOfValues[$i] !== TRUE) {

 echo "<td>" . $numbers["a" . $i . "_pos"] . "</td>";

} else {?> 
<?php  
echo '<td><input type="text" name="a' . $i . '_post" size="1" maxlength="1" /></td>';
?>
