PHP多维数组 - 使其工作

Question

What I am trying to do I do not know the proper name for it so I apologize if I have used the incorrect terminology.

Here is a basic example of what I am trying to achieve:

$arrayData = (4,5,6,7,8,9,10);

$public function setArray($colNum){
    $i = 0;
    while($i < count($arrayData){

Here is where I don't know what to do. I want $colNum to set the number of columns in the new array. so

if $colNum = 4, then $arrayNew[$i][$i][$i][$arrayData[$i]

would then be set. Currently I have created multiple functions that each handle a different number of columns and that works, but it can range from 2 columns to 30 columns and I know there has to be a way to do it more efficiently.

Here's a working example of a 4 column Table (Code not optimized yet)

public function parseTable($tableHeader,$isMoney,$colNum) {
    $tableData = $this->myArray;
    $count = 0;
    $placeHolder = 0;

    while($count < count($tableData)){

        // This hides the column headers
        if($count > $colNum - 1) {
            $col1Array[$placeHolder] = $tableData[$count];
            $col2Array[$placeHolder] = $tableData[$count + 1];
            $col3Array[$placeHolder] = $tableData[$count + 2];
            $col4Array[$placeHolder] = $tableData[$count + 3];
            $placeHolder ++;
        }

        $count = $count + $colNum;

    }

    // Remove the empty lines from the array
    $col1Array = array_values(array_filter($col1Array));
    $col2Array = array_values(array_filter($col2Array));
    $col3Array = array_values(array_filter($col3Array));
    $col4Array = array_values(array_filter($col4Array));

    // Put the 0 back in the array
    $col1Array = array_values(str_replace('~',0,$col1Array));
    $col2Array = array_values(str_replace('~',0,$col2Array));
    $col3Array = array_values(str_replace('~',0,$col3Array));
    $col4Array = array_values(str_replace('~',0,$col4Array));

    $count = 0;
    $tableHTML = "<table class=\"table table-striped table-hover\"  data-toggle=\"table\"
           data-search=\"true\"
           data-show-columns=\"true\"
           data-pagination=\"true\"
        >
        <thead>
            <tr>
                <th>$tableHeader[0]</th>
                <th>$tableHeader[1]</th>
                <th>$tableHeader[2]</th>
                <th>$tableHeader[3]</th>
            </tr>
        </thead>
        <tbody>";

    while($count < count($col1Array)){
        // Replaces empty values with the text set when calling the function
        if($col1Array[$count] == ""){
            $col1Array[$count] = $emptyResult;
        }
        if($col2Array[$count] == ""){
            $col2Array[$count] = $emptyResult2;
        }
        if($col3Array[$count] == ""){
            $col3Array[$count] = $emptyResult3;
        }
        if($col4Array[$count] == ""){
            $col4Array[$count] = $emptyResult4;
        }

        // Converts data into money if specified in the function
        if($isMoney[0] == "Currency"){
            if($col1Array != '0'){$colOne =  money_format('%.2n', $col1Array[$count]);}
            else{$col1Array = "$0.00";}
        }else{$colOne = str_replace('0.00','0',$col1Array[$count]);}
        if($isMoney[1] == "Currency"){
            if($col2Array != '0'){$colTwo =  money_format('%.2n', $col2Array[$count]);}
            else{$colTwo = "$0.00";}
        }else{$colTwo = str_replace('0.00','0',$col2Array[$count]);}
        if($isMoney[2] == "Currency"){
            if($col3Array != '0'){$colThree =  money_format('%.2n', $col3Array[$count]);}
            else{$colThree = "$0.00";}
        }else{$colThree = str_replace('0.00','0',$col3Array[$count]);}
        if($isMoney[3] == "Currency"){
            if($col4Array != '0'){$colFour =  money_format('%.2n', $col4Array[$count]);}
            else{$colFour = "$0.00";}
        }else{$colFour = str_replace('0.00','0',$col4Array[$count]);}

        $tableHTML = $tableHTML . "
        <tr>
            <td>$colOne</td>
            <td>$colTwo</td>
            <td>$colThree</td>
            <td>$colFour</td>
        </tr>";
        $count++;
    }

    $tableHTML = $tableHTML . "
        </tbody>
    </table>";

    $this->tableHTML = $tableHTML;
    $this->col1Array = $col1Array;
    $this->col2Array = $col2Array;
    $this->col3Array = $col3Array;
    $this->col4Array = $col4Array;
    $this->totalRows = count($this->col1Array);
}

Here is a solution with array_push:

$arrayData = array(4,5,6,7,8,9,10);
$setArray = function($colNum) use($arrayData) {
    $new_array = array();
    for ($i = 0; $i < $colNum; $i++){
        $old_array = array();
        array_push($new_array, $old_array);
    }
    array_push($new_array, $arrayData);
    return $new_array;
};

$new_array = $setArray(5);

echo '<pre>';
die(var_dump($new_array));
