如何忽略行尾的數字以比較字符串？

Question

我每次運行我的文件時都會測試一些行，但它們並不總是相同的行。我想要做的就是在另一條線上測試它們是否相同。這個問題的部分原因是因爲在每行結尾處都有數字，我不想在進行比較時考慮這些數字。

在片段下面我想補充一點，對，我知道會出來，這樣，如果它發現它，它返回一個查詢，我需要運行到屏幕上的行每行比較其他功能

error: there were errors found during runtime 12.0 
warning: incorrect info 1.0 
warning: file at 'C://localhost/myfiles' not found 0.0 
warning: file at 'C://localhost/css' not found 0.0 
warning: file at 'C://localhost/js' not found 0.0 
warning: file at 'C://localhost/assets' not found 5615612.0 

這是我試圖做的，但我不知道如何忽略數字，以便實際上可以比較線條。 所有這些發生在第一部分運行之後，我得到的數字大於0.0。

意思是這條線得到比較。

error: there were errors found during runtime 12.0 
warning: incorrect info 1.0 
warning: file at 'C://localhost/assets' not found 5615612.0 

if ("error: there were errors found during runtime 12.0" == line){ 
    //run this query for database runtimeDB 
} 
if("warning: incorrect info 1.0" == line){ 
    //this query 
    //+1 for incorrectInfoDB 
} 
if("warning: file at 'C://localhost/myfiles' not found 0.0" == line){ 
    //this query 
    //+1 for incorrectInfoDB 
} 
if("warning: file at 'C://localhost/css' not found 0.0" == line){ 
    //this query 
    //+1 for outerfilesDB 
} 
if("warning: file at 'C://localhost/css' not found 0.0" == line){ 
    //this query 
    //+1 for outerfilesDB 
} 
if("warning: file at 'C://localhost/js' not found 0.0" == line){ 
    //this query 
    //+1 for outerfilesDB 
} 
if("warning: file at 'C://localhost/assets' not found 0.0" == line){ 
    //this query 
    //+1 for outerfilesDB 
} 

這是我試過的實際代碼。有重用的代碼可以被優化。最後，所有內容都保存在一個數組中，並且所有數組都會根據查詢查詢的數據庫打印出來。

function compare_RT(){ 
    var text = $('textarea').val(); 
    var lines = text.split("\n"); 
    var runtimeDB= []; 
    lines.forEach(function(line){ 

     var string0 = "error: there were errors found during runtime" 

     if(line.includes(string0)){ 
      runtimeDB.push(line); 
     } 
    }); 
return runtimeDB; 
} 
function compare_IInfo(){ 
    var text = $('textarea').val(); 
    var lines = text.split("\n"); 
    var incorrectInfoDB= []; 
    lines.forEach(function(line){ 

     var string0 = "error: there were errors found during runtime" 
     var string1 = "warning: file at 'C://localhost/myfiles' not found" 

     if(line.includes(string0)){ 
      incorrectInfoDB.push(line); 
     } 
     if(line.includes(string1)){ 
      incorrectInfoDB.push(line); 
     } 
    }); 
return incorrectInfoDB; 
} 

function getLines() { 
 
    var text = $('textarea').val(); 
 
    var lines = text.split("\n"); 
 
    var requiredLines = []; 
 
    lines.forEach(function(line) { 
 
    number = line.match(/\d+\.\d+$/); 
 
    if (number != null && number[0] > 0) 
 
     requiredLines.push(line); 
 
    }); 
 
    return requiredLines; 
 
} 
 

 

 
$(document).ready(
 
    function() { 
 
    $('#printlogs').html(getLines().join('<br>')); 
 
    });

我敢肯定，你可以將它適應您的解決方案。

function trim_numbers($string) { 
    //Get the numbers after the last whitespace. 
    //strrchr — Find the last occurrence of a character in a string. 
    $numbers = strrchr($string, ' '); 

    //Replace found numbers with nothing (''). 
    //$numbers is now equal to ' 12.0'. 
    return str_replace($numbers, '', $string); 
} 

echo trim_numbers("error: there were errors found during runtime 12.0"); 

輸出：

error: there were errors found during runtime
