$a= array("Three", "two", "Four", "five","ten");
foreach($a as $key => $val) {
echo "$key -> $val <br>";
}
Output
0 -> Three
1 -> two
2 -> Four
3 -> five
4 -> ten
We can loop through an array to display each element of the
array. This code will display all the element of an array. This is very useful
in many occasions where a list is to be displayed. We will see the application
of this in check box value collection.
$a= array("Three", "two", "Four", "five","ten");
$max=sizeof($a);
for($i=0; $i<$max; $i++) {
echo "$a[$i] ,";
}
$a= array("Three", "two", "Four", "five","ten");
echo $a[2]; // Output is Four
Using Key
$mark=array("John"=>85,"Raju"=>75,"Alex"=>48,"Ronald"=>52);
echo $mark[Alex]; // Output is 48
$a= array("Three", "two", "Four", "five","ten");
print_r($a);
The output of the above code is here.
Array ( [0] => Three [1] => two [2] => Four [3] => five [4] => ten )
Same way here is one more array
$ar=array("FName"=>"John","Address"=>"Streen No 11 ","City"=>"Rain Town","Country"=>"USA");
print_r($ar);
The output is here
Array ( [FName] => John [Address] => Streen No 11 [City] => Rain Town [Country] => USA )
There are other way like using foreach function to display the elements of an array
$ar=array("FName"=>"John","Address"=>"Streen No 11 ",
"City"=>"Rain Town","Country"=>"USA");
foreach($ar as $key => $val) {
echo "$key -> $val <br>";
}
Output
FName -> John
Address -> Streen No 11
City -> Rain Town
Country -> USA

how to get only key and key => values of Multidimensional Arrays ? like this way 1=>a,2=>b,3=>c answer= 1,2,3 and another one 1-A=>1,2,3 2-B=>1,2 means here a1 is array then A is also array under 1 and 1,3,2 is value of A. so i want this like that way. |
