PHP full angle to implement code _php tips

Copy Code code as follows:

/**
* Converts a string containing full-width numeric characters, letters, spaces, or '%+-() ' characters to the corresponding half-width characters
* @access Public
* @param string $str to convert string
* @return string $STR processing after strings
*/
function Make_semiangle ($STR)

$arr = Array (' 0 ' => ' 0 ', ' 1 ' => ' 1 ', ' 2 ' => ' 2 ', ' 3 ' => ' 3 ', ' 4 ' => ' 4 ', ' 5 ' => ' 5 ', ' 6 ' => ' 6 ', ' 7 ' = > ' 7 ', ' 8 ' => ' 8 ', ' 9 ' => ' 9 ', ' A ' => ' a ', ' B ' => ' B ', ' C ' => ' C ', ' d ' => ' d ', ' e ' => ' e ', ' F ' =&gt ; ' F ', ' g ' => ' g ', ' H ' => ' h ', ' I ' => ' I ', ' J ' => ' J ', ' K ' => ' K ', ' l ' => ' l ', ' m ' => ' m ', ' n ' => ' n ', ' o ' => ' o ', ' P ' => ' P ', ' Q ' => ' Q ', ' R ' => ' R ', ' s ' => ' s ', ' t ' => ' t ', U ' => ' u ', ' V ' => ' V ', ' W ' => ' W ', ' x ' => ' x ', ' y ' => ' y ', ' z ' => ' z ', ' a ' => ' a ', ' B ' => ' B ', ' C ' => ' C ', ' d ' => ' d ', ' E ' =& Gt ' E ', ' F ' => ' f ', ' G ' => ' g ', ' H ' => ' h ', ' I ' => ' I ', ' J ' => ' J ', ' K ' => ' K ', ' l ' => ' l ', ' m ' => ' m ' , ' n ' => ' n ', ' o ' => ' o ', ' P ' => ' P ', ' Q ' => ' Q ', ' R ' => ' R ', ' s ' => ' s ', ' t ' => ' t ', ' u ' => ' u ', ' V ' => ' V ', ' W ' => ' W ', ' x ' => ' x ', ' y ' => ' y ', ' z ' => ' z ', ' (' => ' (', ') ' => ') ', ' (' => ' [', '] ') ' => '] ', ' =&GT ' [', ' ' ' => '] ', ' ' => ' [', ' ' => '] ', ' ' ' => ', ' ' => ', ', ' ' => ' [', ' ' => '] ', ' {' => ', ', ' '} ' => '} ', ' "' => ' < ', '" ' => ' > ', '% ' => ', ' + ' => ' + ', '-' => '-', '-' => '-', ' ' => '- ', ': ' => ': ', '.

}

Copy Code code as follows:

<?php
$str = "0123abcdfws\",.? <> {}[]*&^%#@! ~ () +-|:; ";
echo "$str";
echo "<br/>";
$str = Preg_replace ('/\xa3 ([\xa1-\xfe])/e ', ' Chr (ORD) \1) ', $str);
Echo $str;
?>

Also share a function for everyone

In many forms that collect user information, expect the user to enter a half-width character, however, no matter how you emphasize, how to remind, or there will be careless users to submit full-width data, in fact, in some novice eyes, the whole horn and half angle there is no difference, even they will feel: I submitted clearly is the correct information, Why would you be prompted with an error?

In fact, the full-width and Half-width have one by one correspondence, and most users do not intentionally input the wrong information, so we can use the program to avoid this situation, at most, can be converted to give the user a chance to confirm, so that may be able to give users a better experience.

Here is a function that implements the interchange between the character half-width and the full angle.

Copy Code code as follows:

<?php
Header ("content-type:text/html; Charset=utf-8 ");

First argument: Passing in the string to be converted
Second parameter: Take 0, half angle turn whole angle, take 1, full angle to half angle
