note 87816 added to function.preg-replace

/* Coding across linux, mac, and windows gets annoying dealing with errors resulting from EOL format in config files, etc. Standardize to CRLF format. Instead of using one regex I just broke this up into smaller groups - may take longer to execute three statements rather than one, but it also granularizes the use case. */ //different formats all living together $s = "Testing 1.\r" . "Testing 2.\n" . "Testing 3.\r\n" . "Testing 4.\n\r:END"; $s = preg_replace("/(?<!\\n)\\r+(?!\\n)/", " :REPLACED: \r\n", $s); //replace just CR with CRLF $s = preg_replace("/(?<!\\r)\\n+(?!\\r)/", " :REPLACED: \r\n", $s); //replace just LF with CRLF $s = preg_replace("/(?<!\\r)\\n\\r+(?!\\n)/", " :REPLACED: \r\n", $s); //replace misordered LFCR with CRLF echo $s; /* output: Testing 1. :REPLACED: Testing 2. :REPLACED: Testing 3.
