trimming a string in php

问题

i'm still quite new to programming, so please excuse me.

I need to do the following:

Right now i have a string being output with two value: one with characters and numbers, a comma and the second with just a boolean value.

9fjrie93, 1

I would like to trim the string so it just ourputs as the boolean value. e.g.

I then need to perform an equality check on the boolean value. If it's 1 do one thing, else do something else. Would a simple if statement suffuce?

Thanks very much

回答1:

No need for explode if it's always the last character.

<?php
$val = '9fjrie93, 1';
if( substr( $val, -1 ) === '1' ) {
    // do stuff.
}
else {
    // do stuff. Just other stuff.
}

回答2:

How about:

$vals = explode(", ", "9fjrie93, 1");
if ($vals[1]) ...

回答3:

You can also use list to name the results returned:

$original_str = '9fjrie93, 1';
list($characters, $boolean) = explode(', ', $original_str);
echo $boolean;

回答4:

Try this:

    $str = '9fjrie93, 1';
    $str = explode(', ', $str); //it returns array('9fjrie93', '1')
    $str = end($str); //takes the last element of the array

回答5:

$mystring = '9fjrie93, 1';
$findme   = ',';
$pos = strpos($mystring, $findme);
$i= substr($mystring,$pos);

回答6:

$string = "9fjrie93, 1";
$val = substr($string, (strrpos($string, ',')+1));

Don't use explode since it's slower

回答7:

If the 1 is always at the end of the line, you can do:

$line = '9fjrie93, 1'
if ( $line[strlen([$line])-1] == '1' ) {
    // do stuff
} else {
    // do other stuff
}

Which should at least perform better than explode, str_replace and substr solutions.

回答8:

$pos = strpos($source_str, ',');
substr($source_str, $x_pos + 1);

hope this will solve it.

回答9:

 $output = str_replace(',', '', strstr('9fjrie93, 1', ','));
 if( $output == '1' ) {
   ....do something
  } else {
  ...do something else
  }
