Array Manipulation

[wrgill999]

hi.

ex) array with 40 values. i need to take values 28,29 and 30, and concatenation them and put the result into value 28. i then need to "get rid of" 29 and 30 so that value 31 becomes value 29.

before:
28="I
29=like to
30=eat bugs"
31=new value
32=another value

after:
28="I like to eat bugs"
29=new value
30=another value
...

thanks.

First you hope and pray 🙂

No sorry I looked into it and thought yeah that would be a cool idea but alas I do not know how to do it.

this should work. though the code isnt very elegant

$numbers = array(40);
for($i=0;$i<41;$i++){
$numbers[$i] = $i;
}
for($i=0;$i<41;$i++){
echo $numbers[$i]."|";
}
// O/P = 0|1|2|3|4|5|6|7|8|9|10|11|12|13|14|15|16|17|18|19|20|21|22|23|24|25|26|27|28|29|30|31|32|33|34|35|36|37|38|39|40|
$numbers[28] = $numbers[28].$numbers[29].$numbers[30];
while($x<41){
if($x>28){
$numbers[$x] = $numbers[$x+2];
}
$x++;
}
?>
<BR>
<?php
for($i=0;$i<41;$i++){
echo $numbers[$i]."|";
}
// O/P : 0|1|2|3|4|5|6|7|8|9|10|11|12|13|14|15|16|17|18|19|20|21|22|23|24|25|26|27|282930|31|32|33|34|35|36|37|38|39|40|||
?>
