在PHP中删除表上的rowspan

Question

有这个表我想加载到一个多维数组。问题是由于表具有rowspan值，每行可能具有不同的单元格数。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）（有5k行。）

我必须像这样添加这个表才能拥有一个合适的数组。

删除第一行的colspan值很简单。但是在当前方法中删除rowspans有时会在数组中产生额外的值。

我目前的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;
                }
                $satir[] = str_replace('&nbsp;', '', strip_tags($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>';
?>

我的当前输出样本:(看到一些数组值中有21个，23个和17个项目。正确一个是21个项目。（20个作为索引值）） - 不要删除示例输出中的表值 -

使用工作代码更新解决方案：目前使用“***”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('&nbsp;', '***', $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>';
?>

基于@deceze的有用评论，我使用了不同的方法来解决问题。下面的代码将完成工作。但它会用***填充所有空字段。您可能需要重新访问整个数组以将其清空。 （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]='';
        }
    }
}

也许这在最近一段时间会更有帮助。我们可以使用各种工具来像这样删除合并的行和/或列：

import React, { Component } from 'react';
import MapView, { Marker } from 'react-native-maps';
import { View, Text, StyleSheet, Dimensions } from 'react-native';

let { width, height } = Dimensions.get('window');

const LATITUDE = 31.78825;
const LONGITUDE = 34.4324;
const LATITUDE_DELTA = 0.0922;
const LONGITUDE_DELTA = 0.0421;

class Map extends Component {
    constructor(props) {
        super(props);
        this.state = {
            error: null,
            width: width,
            marginBottom: 1,
            region: {
                latitude: LATITUDE,
                longitude: LONGITUDE,
                latitudeDelta: LATITUDE_DELTA,
                longitudeDelta: LONGITUDE_DELTA,
            }
        };

    }
    _findMe = async () => {


        this.watchID = await navigator.geolocation.watchPosition(
            ({ coords }) => {
                const { latitude, longitude } = coords
                this.setState({
                    region: {
                        latitude,
                        longitude,
                        latitudeDelta: LATITUDE_DELTA,
                        longitudeDelta: LONGITUDE_DELTA,
                    }
                })
            });

        await navigator.geolocation.getCurrentPosition(
            (position) => {
                this.setState({
                    region: {
                        latitude: position.coords.latitude,
                        longitude: position.coords.longitude,
                        latitudeDelta: LATITUDE_DELTA,
                        longitudeDelta: LONGITUDE_DELTA,
                    }
                })
            },
            (error) => console.log(JSON.stringify(error)),
            { enableHighAccuracy: true, timeout: 20000, maximumAge: 1000 }
        )
    }

    componentDidMount() {
        this._findMe();
    }
    componentWillUnmount() {
        navigator.geolocation.clearWatch(this.watchId);
    }
    render() {
        const { region } = this.state;
        return (
            <View style={styles.container}>
                <MapView
                    style={[styles.map, { width: this.state.width }]}
                    style={StyleSheet.absoluteFill}
                    onMapReady={() => console.log(this.state.region)}
                    showsUserLocation
                    followsUserLocation={true}

                {/* <Text>{this.state.region.latitude}</Text> */}
            </View>
        );
    }
}

const styles = StyleSheet.create({
    container: {
        flex: 1,
        justifyContent: 'center',
        alignItems: 'center',
        flexDirection: 'row',
        justifyContent: 'space-between',
        padding: 30,
        flex: 1,
        alignItems: 'center'
    },
    map: {
        position: 'absolute',
        zIndex: -1,
        top: 0,
        left: 0,
        right: 0,
        bottom: 0,
    },
});

export default Map;
