Hello everbody, I have noticed something quite strange, i have a piece of code that looks like, i removed some of it to make it readable: there are no statements in the code that would cause the termination of the method before reaching the last line, no return, die or whatever. <? echo "\nBegin\n"; /* some code that builds a string of a few hundred bytes*/ /* a loop that ads ads numbers to the ascii vals of those string named $enc */ /* a loop that swaps all the neighboring chars in the string */ echo "swap: ".$enc."\n"; // swap 1st and 2nd half of string $len=strlen($enc); $enc=substr($enc,$len/2,$len/2).substr($enc,0,$len/2); echo "swp2: ".$enc."\n"; echo "end\n"; ?> This thing is part of a object method, which is called repeatedly. There absolutely NO way 'end' could be printed here without 'swp2' being printed, right, but it does. Also i have occurences of 'swap' without a matching 'end' or 'swp2', like this: (the garbage is the content of '$enc', removing it from the output causes the error to dissappear) -output- Begin swap: 0064277255621244332329528893584643078166114004540827;5>862126663:629;888;;58 664307819;fX$reJxre|"yuw%iVft$rhyuujlnnçm5wi(vkq#ch|ij&fj2 .25C18U8oej|kf!py~3364e\tj||whi(goxk07;2iYximee~%vo~2y82X:nebyif#qwuvwwg swp2: ft$rhyuujlnnçm5wi(vkq#ch|ij&fj2 .25C18U8oej|kf!py~3364e\tj||whi(goxk07;2iYximee~%vo~2y82X:nebyif#qwuvwwg0064 277255621244332329528893584643078166114004540827;5>862126663:629;888;;586643 07819;fX$reJxre|"yuw%iV end Begin swap: 0054716330009693653323102831238781328247354221531537080463:95@4734928:223572 1<2823<8\:nhig#gfM{vo#wsk rk)qkGwvpdudkm#mgg(zmnvppemskhrgC!lxtj3F06H;xokwzj3z33N:|fi|xd7v28TBegin swap: 0034211011257391046799446105509563315163822007167287673;775?=69<<91<;601553< 161375F8eqa"oe"ufd!sćItp{fny&nnwrr&uar%n~fnf1!3/6B92t2tv!keUvlio3g27k;senhQ) omy{0e65e;brfxV%wzdv7g70i2ýrfoY%jrni swp2: !sćItp{fny&nnwrr&uar%n~fnf1!3/6B92t2tv!keUvlio3g27k;senhQ)omy{0e65e;brfxV%wz dv7g70i2ýrfoY%jrni0034211011257391046799446105509563315163822007167287673;77 5?=69<<91<;601553<161375F8eqa"oe"ufd end Begin swap: 00549629613229801512122201313670455389527981851464=:2:4997727A;:21981;306703 59349588`7mlmkvmF!pkk{lgv"g}|hg%sţf"pk fhXexmečqmf(nzc'ovJmyovzin|ukpk9B02G?qsuxtf1270gEnqwl34=5jK}f17=8vXzpmotn swp2: pkk{lgv"g}|hg%sţf"pk fhXexmečqmf(nzc'ovJmyovzin|ukpk9B02G?qsuxtf1270gEnqwl34=5jK}f17=8vXzpmotn005 49629613229801512122201313670455389527981851464=:2:4997727A;:21981;306703593 49588`7mlmkvmF! end Begin swap: 002471894193230257221322567045301134119648109371:9=1>6238:5:52136656>3457011 4;bNmtpmjl˙n5sL)rG"hiMxyjeohf"xgz rn#dnBueoftgvqdsnk5omTqfth AnZjesh2#66H7erhruu#stj)z26@.9382qTwsqfkoöm5y22B6238:5:52136656>34570114;bNm tpmjl˙n5sL)rG"hiMxyjeohf"xgz r end Begin swap: 00547198053854516883507941428066511232699173281113A7>::84385:<7:0<>51<640:68 192521?3I9qnyN"ojlm)zcxupjm%ckl(qtRhv$o*"}qzu\15>6dYt|ujdznlpikxtx2581xPetv n8782uLifn{0x38G=rvxmvdxg swp2: pjm%ckl(qtRhv$o*"}qzu\15>6dYt|ujdznlpikxtx2581xPetvn8782uLifn{0x38G=rvxmvdxg 00547198053854516883507941428066511232699173281113A7>::84385:<7:0<>51<640:68 192521?3I9qnyN"ojlm)zcxu end-output- Multiple cases of malfunction in this output, After 2nd Begin: method was not executed properly, even though script continued afterwards. The next Blocks seem to miss either the \n before begin or the \n after end in the fourth block, swap and end are displayed while swp2 is not When i start to reduce the code by either removing $enc from the output or deleting the loops that manipulate the string before, the echos come in the right order and ammount... What can i do, nothing crashed so i dont have a gdb backtrace for an bug report. I cant provide all the code, neither can i reduce the code without the error do disappear The problem occured on PHP 4.04pl1 on Apache 1.3.x on Linux PHP 4.04 on Apache 1.3.x on Linux PHP 4.06 on Apache 1.3.x on W2K thanks Jens
