How to skip Key and value from array inside foreach? - php

Question

I have struggle in set start point in PHP array
PHP CODE
for($k=0; $k<count($AddClmn); $k++){
$ord = 0;
foreach($AddClmn[$k] as $ky=>$vl){
$clmns[] = array('head'=>$ky, 'src'=>$vl, 'typ'=>'datatyp', 'NEMERIC'=>'', 'wdth'=>'70', 'ord'=>$ord);
$ord++;
}
}
file_put_contents('Tracing.txt', print_r($clmns, true));
My actual output is above PHP code
Array
(
[0] => Array
(
[head] => locid
[src] => 1
[typ] => datatyp
[NEMERIC] =>
[wdth] => 70
[ord] => 0
)
[1] => Array
(
[head] => hhs
[src] => 2525252
[typ] => datatyp
[NEMERIC] =>
[wdth] => 70
[ord] => 1
)
[2] => Array
(
[head] => LA0
[src] => 9831808.388559164
[typ] => datatyp
[NEMERIC] =>
[wdth] => 70
[ord] => 2
)
)
in above result i want skip first two array and i want 3 rd array as start with index 0. how to set pointer or any way to face this situation? i except result is
[0] => Array
(
[head] => LA0
[src] => 9831808.388559164
[typ] => datatyp
[NEMERIC] =>
[wdth] => 70
[ord] => 2
)
[1] => Array
(
[head] => LA1
[src] => 12920638.804462105
[typ] => datatyp
[NEMERIC] =>
[wdth] => 70
[ord] => 3
)
how to solve this prob ?

Answer 1

I think you need this -
foreach($AddClmn[$k] as $ky=>$vl){
if(substr( $ky, 0, 2 ) === "LA") {
//your code
}
} // end for loop

Answer 2

for($k=2; $k<count($AddClmn); $k++){
$ord = 0;
foreach($AddClmn[$k] as $ky=>$vl){
$clmns[] = array('head'=>$ky, 'src'=>$vl, 'typ'=>'datatyp', 'NEMERIC'=>'', 'wdth'=>'70', 'ord'=>$ord);
$ord++;
}
}
file_put_contents('Tracing.txt', print_r($clmns, true));
Use this code..

Answer 3

//you have an array like that
$data = array(
'0' => 'Hello', //you want to skip this
'1' => 'Hello1', //you want to skip this
'2' => 'Hello2',
);
$skipped = array('0', '1');
foreach($data as $key => $value){
if(in_array($key, $skipped)){
continue;
}
//do your stuf
}

Answer 4

// The following lines will remove values from the first two indexes.
unset($array[0]);
unset($array[1]);
// This line will re-set the indexes (new array will set from '0' index)
$array = array_values($array);
// The following line will show the new content of the array
print_r($array);

Answer 5

With PHP >= 5.3 Use this function to flatten (aka remove one "layer") your array by one level:
function flatten(array $array) {
$return = array();
array_walk_recursive($array, function($a) use (&$return) { $return[] = $a; });
return $return;
}
