我有一张纸张拉取值基于

if ($slaHours >= 0 & $slaHours <= 72) 

我想要做的是设置这些值的颜色,如果值小于12.我仍然想显示大于12且小于72的值,所以我尝试的代码是

$styleArray = array(
'font'  => array(
    'bold'  => true,
    'color' => array('rgb' => 'FF0000'),
));

if ($slaHours >= 0 & $slaHours <= 72)
    $slaHours = $objWorksheet->getCellByColumnAndRow(3, $row)->getValue();
    if($slaHours <=12) {    
        $slaHours = $objWorksheet->getCellByColumnAndRow(3, $row)->getValue()->applyFromArray($styleArray); 

但是,我得到一个致命的错误

“Call to a member function applyFromArray() on a non-object “

这个PHP的东西很新,所以非常感谢任何有助于这项工作的帮助.

谢谢

解决方法:

applyFromArray()是PHPExcel_Cell对象的一个​​方法,而不是单元格值(除非单元格包含富文本,这是一个简单的PHP数据类型)….所以你需要针对单元格调用它

$objWorksheet->getCellByColumnAndRow(3, $row)->applyFromArray;

但是如果你需要一个基于单元格值的样式,那么你应该使用条件样式.有关详细信息,请参阅开发人员文档的4.6.23节(“条件格式化单元格”),并查看示例中的08conditionalformatting.php

$objConditionalStyle = new PHPExcel_Style_Conditional();
$objConditionalStyle->setConditionType(PHPExcel_Style_Conditional::CONDITION_CELLIS)
    ->setOperatorType(PHPExcel_Style_Conditional::OPERATOR_LESSTHAN)
    ->addCondition('12');
$objConditionalStyle->getStyle()->getFont()->getColor()->setRGB('FF0000');
$objConditionalStyle->getStyle()->getFont()->setBold(true);

$conditionalStyles = $objWorksheet->getStyle('A3')
    ->getConditionalStyles();
array_push($conditionalStyles, $objConditionalStyle);
$objPHPExcel->getActiveSheet()->getStyle('A3')
    ->setConditionalStyles($conditionalStyles);
