I have two php arrays
$arra = array('one', 'two', 'five', 'seven');
$arrb = array('black', 'white', 'gold', 'silver');
I need to create variables, like this way:
foreach ($arra as $el) {
$el = $arrb[index of $el];
}
So echoing resulting variables:
echo $one should be black
echo $two should be white and so on.
How to do that?
Try with array_combine() and then use foreach() to make dynamic variables. array_combine()- Creates an array by using one array for keys and another for its values
<?php
$arra = array('one', 'two', 'five', 'seven');
$arrb = array('black', 'white', 'gold', 'silver');
$result = array_combine($arra, $arrb);
foreach($result as $key=>$value){
${$key} = $value;
}
echo $two;
?>

OR use extract() after combining $arra and $arrb. extracts()-
Imports variables into the current symbol table from an array.
<?php
$arra = array('one', 'two', 'five', 'seven');
$arrb = array('black', 'white', 'gold', 'silver');
$result = array_combine($arra, $arrb);
extract($result, EXTR_PREFIX_SAME,'');
echo "$one, $two, $five, $seven";
?>

You can actually set a variable's name using a variables value, You need something like this:
for($x=0; $x < count($arra); $x++){
$$arra[$x] = $arrb[$x];
}
Notice the double $$. This is not a mistake.
I think this is what you want:
$arra = array('one', 'two', 'five', 'seven');
$arrb = array('black', 'white', 'gold', 'silver');
foreach($arra as $key=>$ela) {
$elb = $arrb[$key];
${$ela} = $elb;
}
echo $one;
echo $two;
echo $five;
echo $seven;
For using strings as variables I found this link helpful.
