Accessing Arrays inside Arrays In PHP
Accessing Arrays inside Arrays In PHP, the code below will show you how to access an Array inside an Array using a for loop.
(1) An Array named $robot is being created .
(2) Inside every array index of $robot , contains another Array.
(3) To print the Array inside . the programmed will first loop through the main Array $robot. while in the main Array $robot it will loop through the child Array .
Use for loop to Print out
<!DOCTYPE html>
<html>
<body>
<?php
$robot[0]=array(1,"bBot","1111");
$robot[1]=array(2,"cBot","2222");
$robot[2]=array(3,"dBot","3333");
$rlength= sizeof($robot);
for ($x = 0; $x < $rlength; $x++) {
for ($y = 0; $y <sizeof($robot[$x]); $y++) {
echo $robot[$x][$y].",";
}
echo "
";
}
Output
1,bBot,1111, 2,cBot,2222, 3,dBot,3333,
Use var_dump to Print out
Use var_dump to print out readable code for human
<?php
$robot[0]=array(1,"bBot","1111");
$robot[1]=array(2,"cBot","2222");
$robot[2]=array(3,"dBot","3333");
foreach ($robot as $item){
echo '
<pre>'; var_dump($item);
}
Output
array(3) {
[0]=>
int(1)
[1]=>
string(4) "bBot"
[2]=>
string(4) "1111"
}
array(3) {
[0]=>
int(2)
[1]=>
string(4) "cBot"
[2]=>
string(4) "2222"
}
array(3) {
[0]=>
int(3)
[1]=>
string(4) "dBot"
[2]=>
string(4) "3333"
}
Use print_r to Print out
<!DOCTYPE html> <html> <body> <?php $robot[0]=array(1,"bBot","1111"); $robot[1]=array(2,"cBot","2222"); $robot[2]=array(3,"dBot","3333"); print " <pre>"; print_r($robot); print "</pre> "; ?> </body> </html>
Output
Array
(
[0] => Array
(
[0] => 1
[1] => bBot
[2] => 1111
)
[1] => Array
(
[0] => 2
[1] => cBot
[2] => 2222
)
[2] => Array
(
[0] => 3
[1] => dBot
[2] => 3333
)
)
