Previous Comments: ------------------------------------------------------------------------ [2003-01-22 14:52:19] [EMAIL PROTECTED] Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php The replacment is done in the order the array was created, if you want it to be done based on array keys that run an appropriate sorting function before executing the preg_replace function. ------------------------------------------------------------------------ [2003-01-22 12:14:45] [EMAIL PROTECTED] The search strings used in the preg_replace() function are regular expressions. "[abc]" is a regular expression which matches any of the characters "a", "b" or "c". Either use str_replace() to replace your strings, or learn to use regular expressions <http://de3.php.net/manual/en/pcre.pattern.syntax.php>. ------------------------------------------------------------------------ [2003-01-22 08:41:20] [EMAIL PROTECTED] <?php // Hi, while using the following code i experienced // an interesting behaviour of preg_replace(): $string = "Say a [word0] about [word1] and [word2]"; $search[0] ="[word0]"; $search[1]= "[word1]"; $search[2]= "[word2]"; $replace[0]="betterWord0"; $replace[2]="betterWord2"; $replace[1]="betterWord1"; $string2 = preg_replace($search,$replace,$string); echo "Result is:<BR>" . $string2; echo "<BR><BR>Result should be:<BR> Say a [betterWord0] about [betterWord1] and [betterWord2]"; // result should be: //Say a [betterWord0] about [betterWord1] and [betterWord2] // // but produces: //Say a [betterWord0] about [betterWord2] and [betterWord1] // // Seems like the order in which i build my array // is the order for replacing...and not the index // of $array[$index] // // if you add a ksort it works fine: ksort($search,SORT_NUMERIC); ksort($replace,SORT_NUMERIC); reset($search); reset($replace); $string3 = preg_replace($search,$replace,$string); echo "<BR><BR>Corrected (ksort) Result is:<BR>" . $string3; // // Has someone an idea, about what's happening here? // // just a guy addicted to php ;-) ?> ------------------------------------------------------------------------ [2003-01-22 07:43:39] [EMAIL PROTECTED] <?php // Hi, while using the following code i experienced // an interesting behaviour of preg_replace(): $string = "Say a [word0] about [word1] and [word2]"; $search[0] ="[word0]"; $search[1]= "[word1]"; $search[2]= "[word2]"; $replace[0]="betterWord0"; $replace[2]="betterWord2"; $replace[1]="betterWord1"; $string = preg_replace($search,$replace,$string); echo "Result is:<BR>" . $string; echo "<BR><BR>Result should be:<BR> Say a [betterWord0] about [betterWord1] and [betterWord2]"; // result should be: //Say a [betterWord0] about [betterWord1] and [betterWord2] // // but produces: //Say a [betterWord0] about [betterWord2] and [betterWord1] // // Seems like the order in which i build my array // is the order for replacing...and not the index // of $array[$index] // // // Has someone an idea, about what's happening here? // // just a guy addicted to php ;-) ?> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=21816&edit=1 -- PHP Documentation Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
