Project, using Preg_match to extract the target content, there has been a problem. At first the feeling is that Preg_match has a string length limit, and sure enough, the value of "Pcre.backtrack_limit" is set to only 100000 by default.

Strlen () function and Mb_strlen () function In PHP, the function strlen () returns the length of the string. The function prototypes are as follows: int strlen (string string_input); The parameter string_input is the string to be processed.The

Function for solving the problem of Chinese and English string length The code is as follows: Function strSplit ($ s, $ len ){$ End = '... ';$ Result = '';$ StrLen = strlen ($ s );If ($ strLen Return $ s;}$ Len-= 2;For ($ I = 0; $ I $ C = $ s [$

function Encryptdecrypt ($key, $string, $decrypt) { if ($decrypt) { $decrypted = RTrim (Mcrypt_decrypt (mcrypt_rijndael_256, MD5 ($key), Base64_decode ($string), MCRYPT_MODE_CBC, MD5 (MD5 ($ Key)), "12"); return $decrypted;

This article describes how to solve the length problem that occurs when the PHP preg_match function matches strings in regular expressions. if you want to use the preg_match regular expression to extract the target content, you can refer to the

We usually use the length function to calculate the character length in js. However, it is strange to read the document written by a friend below, the following describes how to calculate the length of a null character or a string. You can use the

This article mainly introduces JS to determine the length of the string 5 methods, and distinguish between Chinese and English, the need for friends can refer to the nextPurpose: To calculate the length of a string (1 characters in English, 2

In the project, use the preg_match regular expression to extract the target content. If there is a problem with live or dead, the code will be tested dead. Later, I suspect that PHP's preg_match has a string length limit, and found that the value

Strlen () and mb_strlen () FunctionsIn PHP, The strlen () function returns the length of the string. The function prototype is as follows:Copy codeThe Code is as follows:Int strlen (string string_input ); The string_input parameter is the string to

Ajax received a different string length issue I use Ajax to pass a parameter, and then PHP receive, with Var_dump print out, the length is 41, and then I copy the same string to PHP, directly var_dump print out, the length is 42. String (41) " [

1: "Byte" is byte, "bit" is bit;2:1 byte = 8 bit;Char is 2 bytes in Java. Java uses unicode,2 bytes (16 bits) to represent one character.ButString str = "compilation";byte[] bytes = Str.getbytes (); I wonder why it takes 3 bytes here?3 byte is 3*8=24

int strlen (String $string)int strlen (string $string) Gets the length of the string $string if the [byte] length of the given string succeeds, and returns 0 if $string is empty.Mb_strlen ()-Gets the length of the stringmixed Mb_strlen (String $str [
