我想将这张表加载到多维数组中。问题在于，由于该表具有行跨度值，每行可能具有不同的单元格计数。所以我必须删除 rowspan 并添加空值而不是这些单元格。
这是我的表(原始文件)(大约有 5k 行。)
我必须像这样添加这个表才能得到一个合适的数组。 
删除第一行的 colspan 值很容易。但是在当前方法中删除行跨度有时会导致数组中出现额外的值。
我当前的 PHP 文件:
<?php
ini_set('display_errors', true);
ini_set('mbstring.internal_encoding','UTF-8');
ini_set("memory_limit", "1024M");
ini_set('max_execution_time', 300);
include('simple_html_dom.php');
// Create a DOM object
$html = new simple_html_dom();
$html->load_file('stok.html');
$table = array();
$kac = array();
foreach($html->find('tr') as $row) {
$satir = array();
$j = 0;
foreach($row->find('td') as $element) {
if($kac[$j]['deger']>0){
$satir[]='';
$kac[$j]['deger']=$kac[$j]['deger']-1;
$j++;
while($kac[$j]['deger']>0){
$satir[]='';
$kac[$j]['deger']=$kac[$j]['deger']-1;
$j++;
}
}else{
$j++;
if(isset($element->rowspan)){
$kac[$j]['deger']=($element->rowspan)-1;
}
$satir[] = str_replace(' ', '', strip_tags($element->innertext));
}
if(isset($element->colspan)){
$sayi=($element->colspan)-1;
for($i=1;$i<=$sayi;$i++){
$satir[] = '';
}
}
}
$table[] = $satir;
}
echo '<pre>';
print_r($table);
echo '</pre>';
?>
我当前的输出示例:(看到一些数组值中有 21、23 和 17 项。正确的是 21 项。(20 作为索引值))--没有删除示例输出中的表值--

使用工作代码更新解决方案:目前用“***”填充所有空单元格
<?php
ini_set('display_errors', true);
ini_set('mbstring.internal_encoding','UTF-8');
ini_set("memory_limit", "1024M");
ini_set('max_execution_time', 300);
include('simple_html_dom.php');
// Create a DOM object
$html = new simple_html_dom();
$html->load_file('stok.html');
$satir = array();
$rowcount = 0;
foreach($html->find('tr') as $row) {
$colcount = 0;
foreach($row->find('td') as $element) {
while($satir[$rowcount][$colcount]!=''){
$colcount++;
}
$satir[$rowcount][$colcount] = strip_tags(str_replace(' ', '***', $element->innertext));
if(isset($element->colspan)){
$sayi=($element->colspan)-1;
for($i=1;$i<=$sayi;$i++){
$satir[$rowcount][$colcount+$i] = '***';
}
}
if(isset($element->rowspan)){
$sayi=($element->rowspan)-1;
for($i=1;$i<=$sayi;$i++){
$satir[$rowcount+$i][$colcount] = '***';
}
}
$colcount++;
}
$rowcount++;
}
echo '<pre>';
print_r($satir);
echo '</pre>';
?>
最佳答案
根据@deceze 的有用评论，我使用了不同的方法来解决问题。下面的代码将完成这项工作。但它会用 *** 填充所有空白字段。您可能需要重新访问整个数组以清空它。 (此代码位于下方)
// Create a DOM object
$html = new simple_html_dom();
$html->load_file('stok.html');
$satir = array();
$rowcount = 0;
foreach($html->find('tr') as $row) {
$colcount = 0;
foreach($row->find('td') as $element) {
while($satir[$rowcount][$colcount]!=''){
$colcount++;
}
$satir[$rowcount][$colcount] = strip_tags(str_replace(' ', '***', $element->innertext));
if(isset($element->colspan)){
$sayi=($element->colspan)-1;
for($i=1;$i<=$sayi;$i++){
$satir[$rowcount][$colcount+$i] = '***';
}
}
if(isset($element->rowspan)){
$sayi=($element->rowspan)-1;
for($i=1;$i<=$sayi;$i++){
$satir[$rowcount+$i][$colcount] = '***';
}
}
$colcount++;
}
$rowcount++;
}
echo '<pre>';
print_r($satir);
echo '</pre>';
?>
下面的代码块将从我上面提到的那些星号中清除数组。
$itemcount=count($satir)-1;
for($i=1; $i<=$itemcount; $i++){
for($j=0; $j<=20; $j++){
if($satir[$i][$j]=='***'){
$satir[$i][$j]='';
}
}
}
