如何在PHP中将变量的值分配给数组

Question

If I have a variable,

 $var1 = 'foo';      //but this value might change over time. 

How can I assign the value of $var1 to array $array1?

I tried

 $array1 = array('key1' => $var1;)

but this doesn't seems to work.

Answer 1

Try the following:

$array1['key1'] = $var1;

You can also do the following:

 $array1 = array( 'key1' => $var1);

But you need to remove ; from your code.

Answer 2

Simple as this.. Just remove the ;

 <?php
 $var1 = 'foo';
 $array1 = array( 'key1' => $var1 );

Answer 3

you can use, $array1 = array('key1' => $var1);

single dimensional array structure:

array('key'=>'value', 'key2'=>'value' ...);

Answer 4

Try

$var1='foo';
    $array1 = array(
        'key1' => $var1
    );

OR

$array1['key1'] = $var1;

Answer 5

Try this, I think this will help you

    $var="abc";
      $array=array('name'=>$var);
       echo $array['name'];
