I have an associative array in php. the content of associative array looks like this:
Array
(
[0] => Array
(
[0] => 3
[1] => 1
[2] => 0
[3] => 50074494
[4] => 25013372
[5] => 2
[6] => 474
[7] => 0
[8] => 0
[9] => 0
[10] => 0
[11] => 985
[12] => 34951
[13] => 18143
[14] => 4
[15] => 2
[16] => 94
[17] => 1
[18] => 1.26
[19] => 7.9
[20] => 2013-06-27 10:19:21
)
[1] => Array
(
[0] => 5
[1] => 1
[2] => 0
[3] => 50078122
[4] => 25000164
[5] => 2
[6] => 463
[7] => 0
[8] => 0
[9] => 0
[10] => 0
[11] => 860
[12] => 28290
[13] => 16944
[14] => 4
[15] => 1
[16] => 94
[17] => 1
[18] => 1.13
[19] => 7.1
[20] => 2013-06-27 10:19:51
)
[2] => Array
(
[0] => 4
[1] => 1
[2] => 0
[3] => 50078630
[4] => 24995538
[5] => 2
[6] => 155
[7] => 0
[8] => 0
[9] => 0
[10] => 0
[11] => 616
[12] => 23203
[13] => 4892
[14] => 3
[15] => 1
[16] => 95

[18] => 1.04
[19] => 6.5
[20] => 2013-06-27 10:20:21

)
I would like to be able to assign the inner array values to a variable. I need variable to look like this:
echo $variable
3 1 0 50074494 25013372 2 474 .. 2013-06-27 10:19:21
.
.
I have this code so far:
$variable;
foreach ($lines as $key => $value) {
foreach ($value as &$val)
{
$variable=$variable . $val . ' ';
}
echo $variable;
echo "\n";
}
with this code it looks like I am getting 3 times of variable. Any ideas what I am doing wrong here?
If you have an array, and you want to store the values in a space-separated string, you could do this:
$string = implode(' ', $array);
echo $string;
So your loop might look like this:
foreach ($lines as $value) {
$value[20] = '"'. $value[20] .'"'; // from comments
echo implode(' ', $value) ."\n";
}
I would recommend the use of implode instead of foreach. Also, it doesn't seem like you need the value of $key
:
foreach ($lines as $value) {
echo implode(" ", $value);
echo "\n";
}
Also, I'm not sure I quite understood your question? What do you mean by "3 times of variable"?
