php for和foreach循环只存储最后一个值

Question

I am looping though one initial array, and specifying values i want. Then i am storing the values i need in an array. Then i am combining those values into a new array, with keys and values. The new array is only storing the last entry of all the data that has been passed to it.

$exampleArray = array();
for ($i = 0; $i < 100; $i++){
    $exampleArray[] = array(
        $A1 =  $Anotherarray[$i][25],
        $A2 = $Anotherarray[$i][26],
        $A3 = $Anotherarray[$i][24],
        $A4 = $Anotherarray[$i][27],
        $A5 = $Anotherarray[$i][28]
    );

    $secondExample = array();

    foreach( $A1 as $i => $val )
    {
        $secondExample[] = array(
            "Field1" => $val,
            "Field2" => ucfirst($A2[$i]),
            "Field3" => ucfirst($A3[$i]),
            "Field4" => ucfirst($A4[$i]),
            "Field5" => ucfirst($A5[$i])
        );
    }

Answer 1

You are declaring $secondExample as a new array on every iteration. Do it like this:

$exampleArray = array();
$secondExample = array();

for ($i = 0; $i < 100; $i++){
    $exampleArray[] = array(
        $A1 = $Anotherarray[$i][25],
        $A2 = $Anotherarray[$i][26],
        $A3 = $Anotherarray[$i][24],
        $A4 = $Anotherarray[$i][27],
        $A5 = $Anotherarray[$i][28]
    );

    $secondExample[$i] = array();
    foreach( $A1 as $j => $val) {
        $secondExample[$i][] = array(
        "Field1" => $val,
        "Field2" => ucfirst($A2[$j]),
        "Field3" => ucfirst($A3[$j]),
        "Field4" => ucfirst($A4[$j]),
        "Field5" => ucfirst($A5[$j])
    );
}
