str-replace

$line-out = str_replace('\r', '', str_replace('\n', '', $line-in)); The above works for me but, I saw a [\n\r] example somewhere and I cannot seem to find it. I just want to get rid any blank lines. The above is in a foreach loop. Thanks for teaching. Lekensteyn You shouldn't use - in variable names ;) $line_out = preg_replace('/[\n\r]+/', '', $line_in); $line_out = str_replace(array("\n", "\r"), '', $line_in); Manual entries: http://php.net/manual/en/function.preg-replace.php http://php.net/manual/en/function.str-replace.php str_replace can be passed an array as: $line_out = str_replace(array

I need to search a string and edit the formatting of it. So far I can replace the first occurrence of the string, but I am unable to do so with the next occurrences of this string. This is what I have working, sort of: if(chartDataString.find("*A") == string::npos){ return;} else{chartDataString.replace(chartDataString.find("*A"), 3,"[A]\n");} If it doesn't find the string, nothing prints at all, so that's not good. I know I need to loop through the entire string chartDataString and replace all occurrences. I know there are a lot of similar posts to this but I don't understand (like this

Some background information: We have an ancient web-based document database system where I work, almost entirely consisting of MS Office documents with the "normal" extensions (.doc, .xls, .ppt). They are all named based on some sort of arbitrary ID number (i.e. 1245.doc). We're switching to SharePoint and I need to rename all of these files and sort them into folders. I have a CSV file with all sorts of information (like which ID number corresponds to which document's title), so I'm using it to rename these files. I've written a short Python script that renames the ID number title. However,

I'm trying to mimic the json_encode bitmask flags implemented in PHP 5.3.0, here is the string I have: $s = addslashes('O\'Rei"lly'); // O\'Rei\"lly Doing json_encode($s, JSON_HEX_APOS | JSON_HEX_QUOT) outputs the following: "O\\\u0027Rei\\\u0022lly" And I'm currently doing this in PHP versions older than 5.3.0: str_replace(array('\\"', "\\'"), array('\\u0022', '\\\u0027'), json_encode($s)) or str_replace(array('\\"', '\\\''), array('\\u0022', '\\\u0027'), json_encode($s)) Which correctly outputs the same result: "O\\\u0027Rei\\\u0022lly" I'm having trouble understanding why do I need to

I have string variable strVar with value as ' "value1" ' and i want to replace all the double quotes in the value with ' \" ' . So after replacement value would look like ' \"value1\" ' How to do this in java? Kindly help me. You are looking for strVar = strVar.replace("\"", "\\\"") DEMO I would avoid using replaceAll since it uses regex syntax in description of what to replace and how to replace, which means that \ will have to be escaped in string "\\" but also in regex \\ (needs to be written as "\\\\" string) which means that we would need to use replaceAll("\"", "\\\\\""); or probably

Is there a reason that I'm not seeing, why this doesn't work? $string = $someLongUserGeneratedString; $replaced = str_replace(' ', '_', $string); echo $replaced; The output still includes spaces... Any ideas would be awesome Laurent Brieu I'll suggest that you use this as it will check for both single and multiple occurrence of white space (as suggested by Lucas Green). $journalName = preg_replace('/\s+/', '_', $journalName); instead of: $journalName = str_replace(' ', '_', $journalName); Try this instead: $journalName = preg_replace('/\s+/', '_', $journalName); Explanation: you are most
