處理中-內容的處理

設置reader和編碼

$file_path = 'test.xls'; $excel5_reader = new PHPExcel_Reader_Excel5(); $excel5_reader->_defaultEncoding = $encoding; $excel2007_reader = new PHPExcel_Reader_Excel2007(); $excel2007_reader->_defaultEncoding = $encoding; $reader = null;if($excel5_reader->canRead($file_path)) {$reader = $excel5_reader; } elseif($excel2007_reader->canRead($file_path)) {$reader = $excel2007_reader; } else {return array(); }

處理多sheet和遍歷內容

• 核心方法：$all_sheets = $table_object->getAllSheets();

$table_object = $reader->load($file_path); $all_sheets = $table_object->getAllSheets(); $i = 0; foreach ($all_sheets as $key => $sheet_obj) {$sheet_title = $sheet_obj->getTitle();$row_iterator = $sheet_obj->getRowIterator();foreach ($row_iterator as $k1 => $row_obj) {$cell_iterator = $row_obj->getCellIterator();} }

處理樣式

• 核心方法： $cell_obj->getStyle();
• 下述方法為轉化為css標準樣式，可以直接拿來使用

$style_object = $cell_obj->getStyle(); $style = [];//css標準樣式$fill_object = $style_object->getFill(); $font_object = $style_object->getFont(); $borders_object = $style_object->getBorders(); $alignment_object = $style_object->getAlignment();$fill_type = $fill_object->getFillType();if (PHPExcel_Style_Fill::FILL_SOLID === $fill_type) {$color = $fill_object->getStartColor()->getRGB();$style['background-color'] = '#'. $color; }$top_border_style = $borders_object->getTop()->getBorderStyle(); $top_border_color = $borders_object->getTop()->getColor()->getRGB(); $top_border_style = $this->_trick_excel_border_style($top_border_style); if (PHPExcel_Style_Border::BORDER_NONE !== $top_border_style) {$style['border-top'] = '1px '. $top_border_style . ' #' . $top_border_color; }$left_border_style = $borders_object->getLeft()->getBorderStyle(); $left_border_color = $borders_object->getLeft()->getColor()->getRGB(); $left_border_style = $this->_trick_excel_border_style($left_border_style); if (PHPExcel_Style_Border::BORDER_NONE !== $left_border_style) {$style['border-left'] = '1px '. $left_border_style . ' #' . $left_border_color; }$bottom_border_style = $borders_object->getBottom()->getBorderStyle(); $bottom_border_color = $borders_object->getBottom()->getColor()->getRGB(); $bottom_border_style = $this->_trick_excel_border_style($bottom_border_style); if (PHPExcel_Style_Border::BORDER_NONE !== $bottom_border_style) {$style['border-bottom'] = '1px '. $bottom_border_style . ' #' . $bottom_border_color; }$right_border_style = $borders_object->getRight()->getBorderStyle(); $right_border_color = $borders_object->getRight()->getColor()->getRGB(); $right_border_style = $this->_trick_excel_border_style($right_border_style); if (PHPExcel_Style_Border::BORDER_NONE !== $right_border_style) {$style['border-right'] = '1px '. $right_border_style . ' #' . $right_border_color; }$font_size = $font_object->getSize(); if (isset($font_size) && $font_size > 11) {$style['font-size'] = $font_size . 'px'; } $font_color = $font_object->getColor()->getRGB(); if (isset($font_color) && $font_color != '000000') {$style['color'] = '#' . $font_color; }$font_bold = $font_object->getBold(); if ($font_bold) {$style['font-weight'] = 'bold'; } $font_italic = $font_object->getItalic(); if ($font_italic) {$style['font-style'] = "italic"; } $font_underline = $font_object->getUnderline(); if ($font_underline && $font_underline != PHPExcel_Style_Font::UNDERLINE_NONE) {$style['text-decoration'] = "underline"; } $font_strikethrough = $font_object->getStrikethrough(); if ($font_strikethrough) {$style['text-decoration'] = "line-through"; }$horizontal = $alignment_object->getHorizontal(); if ($horizontal != 'general') {$style['text-align'] = $horizontal; }$vertical = $alignment_object->getVertical(); if ($vertical != 'bottom') {$style['vertical-align'] = $vertical; }

獲取數據

• 核心方法：$cell_obj->getCalculatedValue();
• 注意防止注入

$cell_obj->getCalculatedValue();//會處理公式和富文本的值 string $cell_obj->getValue();//不處理公式和富文本的值，存在多種類型

處理超鏈接

核心方法：$cell_obj->getHyperlink()->getUrl();

$value = $cell_obj->getCalculatedValue(); $url = $cell_obj->getHyperlink()->getUrl(); $link = '<a href="'.$url.'" target="_blank">' . $value . '</a>';

處理公式

• $cell_obj->getValue();
• 需要先判斷是否是公式值
• 返回格式string，ie A1:E1

if (!$cell_obj->isFormula()) {return null; } $value = $cell_obj->getValue();//A1:E1 preg_match('/([a-zA-Z]+)\(([a-zA-Z]+)(\d+)\:([a-zA-Z]+)(\d+)\)/', $value, $ranges); // 獲得ranges范圍 if (empty($ranges[1])) {return null; }

合并單元格

• $merges = $sheet_obj->getMergeCells();
• 返回的是merge數據數組

$merges = $sheet_obj->getMergeCells();if (empty($merges)) {return null; }$merge_info = []; foreach ($merges as $k => $merge) { //A1:E1preg_match('/([a-zA-Z]+)(\d+)\:([a-zA-Z]+)(\d+)/i', $merge, $ranges); //獲得range范圍 //todo something }

列寬和行高

//行高 $row_iteratior = $sheet_obj->getRowIterator(); $row_hights = [];//實際行高值$i= 0; foreach ($row_iteratior as $k => $row) {$row_height = (int)($sheet_obj->getRowDimension($k)->getRowHeight());$row_hights[$i] = $row_height;$i++; } //列寬 $col_iteratior = $sheet_obj->getColumnIterator(); $col_widths = [];//實際列寬值$i= 0; foreach ($col_iteratior as $k => $col) {$col_width = (int)($sheet_obj->getColumnDimension($k)->getWidth())*7;$col_widths[$i] = $col_width;$i++; }

表格凍結

$freeze = $sheet_obj->getFreezePane(); // 返回 ie： A2

其他問題

空的sheeft的處理

• 有樣式，無數據
• 默認邊框和空白邊框的處理

橫坐標處理

Excel的橫坐標為A、B…、AA、AB類型，需要轉化坐標。

private function _get_sheet_col_key($label) {$col_key_map = [];$abc = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';for ($i=0; $i < 600; $i++) {$a = (int)($i / 26);$b = $i % 26;$column_label = '';if ($a == 0) {$column_label = $column_label . substr($abc, $b, 1);} else {$a = $a -1;$column_label = substr($abc, $a, 1) . substr($abc, $b, 1); }$col_key_map[$column_label] = $i; }return $col_key_map[$label]; }
