From String:-
 Dr/CR,Entry Amount,Value date,Product,Party Code,Party Name,Virtual=\nAccount Number,Locations,RemittingBank,UTR No\nC,500000.0000,30-Mar-15,ABC,XYZ,QWER =\nLTD,LKJH,

To String:- 
 Dr/CR,Entry Amount,Value date,Product,Party Code,Party Name,Virtual Account   Number,Locations,RemittingBank,UTR No\nC,500000.0000,30-Mar-15,ABC,XYZ,QWER  LTD,LKJH,

你可以用preg_替换

preg_replace('~=\n~', " ", $str);
