符合以下顺序的规定:
data:image(any number of characters except of doublequotes)"
因此,从“数据:估算”开始(可在探测、开端、中间的任何部分进行),除“数据”的末尾外,其次为0或更多。
我想在预选中加以使用,这样一来就可以“超越”这种不想要的系列特征。
首先与字面文本<代码>数据:image 相吻合,然后是0或更多特性,即t <代码>, 之后是。
如果你只想数据:估计:
$string = preg_replace( /data:image[^"]*"$/ , data:image" , $string);
如果你只想另一方面:
$string = preg_replace( /data:image([^"]*)"$/ , 1 , $string);
