Hey all: I have this array:
$names = array('a','b','c');
foreach($names as $key => $value ) {
echo $key;
}
where a, b, c come from a name[] field
The input is:
0 1 2
There is an array function to replace the output result as:
1 2 3
I want to rename the first key because I'll insert theme into a mysql table.
Why rename? Just use $key + 1 when needed.
for ($i = count($names) - 1; $i >= 0; $i--)
$names[$i + 1] = $names[$i];
unset($names[0]);
or
array_unshift($names, 0);
unset($names[0]);
or
Just use $key+1 in your query rather than changing the array.
I just found a solution:
$names = array(1 => 'a','b','c');
foreach($names as $key => $value ) {
echo $key;
}
Maybe this if you want to increase all by 1:
$names = array('a','b','c');
foreach($names as $key => $value ) {
$key = $key+1;
}
or
$names = array('a','b','c');
foreach($names as $key => $value ) {
if($key==1) {
$key = $key+1;
}
}
but the second one would not make any sense since it would just be replaced by the second array element.
